Basic Cultivar, Roast, and Cupping Terms

Abyssinia
Ethiopia was formerly known as Abyssinia, or this term may refer a coffee cultivar. Abyssinia is also a cultivar brought to Java in 1928 (not the original Typica brought from Yemen to Batavia, Java via India). Since then, they have been brought to Aceh as well. Another group of Ethiopian varieties found in Sumatra are called “USDA”, after an American project that brought them to Indonesia in the 1950s.
Aceh
Aceh District is north of North Sumatra and produces some very classic Sumatra coffees. The center of coffee in Aceh is Lake Tawar and Takengon, the city by the lake. It often looks like a mispelling of "Ache" but is pronounced "Ah-Chay". Gayo is a name used in relation of Aceh since it is one of the main ethnic groups of the region.
Acidity
Acidity in arabica coffees is almost always considered a positive flavor attribute, yet the term can sound unattractive. People may relate acidity to stomach discomfort, or to sour flavors. This would be incorrect. The acidity in good high-grown arabicas imbues the cup with delicate flavor accents, complexity, and dimension. Good acidity is fleetingly volatile, a momentary sensation, giving effervescence to the cup, and informing the mouthfeel as well. Coffees with no acidity can taste flat. Acidity is not about quantity, it is about quality, and good coffees have a complex balance of many types of acidity: malic, citric, acetic, phosphoric, quinic, to name a few ... and a whole set of chlorogenic acids that are very important to flavor experience as well. Kenyas, which by flavor are some of the higher acid coffees, actually have measurably less than Brazil arabicas (of quinic and citric acids), more of others (malic, phosphoric) and far less than some robusta coffees (chlorgenic acids)! Dark roasts tend to flatten out acidity in flavor. But contrary to the taste, darker roasts have more acidity than lighter roasts. So quantity does not always follow perception. Acidity in coffee might be described by terms like bright, clear, effervescent, snappy, dry, clean, winey, etc. Coffees without acidity tend to taste flat and dull, like flat soda. Acidity is to coffee what dryness is to wine, in a sense. Different coffee origins will possess different kinds of acidity; like the wine-like high notes of some African coffees versus the crisp clear notes of high grown coffees from the Americas. Unpleasant acidy flavors may register as sourness.
Afternose
Commonly used in reference to wine, afternose compliments aftertaste, but refers to residual olfactory sensations after the coffee has left the palate.
Aftertaste
Aftertaste refers to lingering residual sensations in the mouth after coffee has swallowed. It might be distinguished from "finish" which is the final sensations of the coffee while it leaves the mouth. Also see Afternose.
Aroma
The aromatics of a coffee greatly influence its flavor profile and come from the perception of the gases released by brewed coffee. Aroma is greatest in the middle roasts and is quickly overtaken by carbony smells in darker roasts. Aroma is distinct from the dry fragrance of the coffee grounds; in general "fragrance" describes things we do not eat (like perfume) and "aroma" pertains to food and beverage we consume. In cupping, wet aroma refers to the smell of wet coffee grinds, after hot water is added. Aromatics as a term may encompass the entire aroma experience of a coffee. Aromatics are a huge part of flavor perception (remember the "hold your nose and eat an onion" experiment). Aromatics reach the olfactory bulb through the nose and "retro-nasally" through the opening in the back of our palate. While some taste is sapid, perceived through the tongue and palate via papillae, or taste buds, most of flavor quality is perceived through the olfactory bulb.
Arusha
The name of a cultivar from Tanzania, as well as a general trade name for Tanzania coffees from Mount Meru area
Ateng
Ateng, with several sub types, is a common name for Catimor coffees widely planted in Sumatra and other Indonesia isles. One will hear of Ateng Jaluk. This cross between Arabica and Robusta has a reputation for poor flavor. However, there are numerous types of Catimor and in some conditions they can do well in the cup.
Bergendal
Bergendal is found less and less frequently in Sumatra and other parts of Indonesia. It is a low-producing plant of Typica origins. Much of the Typica was lost in the late 1880s, when Coffee Leaf Rust swept through Indonesia. However, both the Bergendal and Sidikalang varieties of Typica can still be found in Sumatra, Sulawesi, and See our Flores Coffee Offerings for more information.">Flores, especially at higher altitudes and in remote areas.
Blue Mountain Cultivar
A C. Arabica Var. Typica coffee that shares other features of Typica plants, but also shows some resistance to CBD: Coffee Berry Disease. It is said to be grown in Papua New Guinea but pure lots have not been found, and we buy a small lot of this cultivar from a plot in Kona, Hawaii each year.
Body
Associated with and sensed by mouthfeel, body is sense of weight and thickness of the brew, caused by the percentage of soluble solids in the cup, including all organic compounds that are extracted from brewing and end up in the cup. Body refers usually to thick or thin, heavy or light, full-bodied or watery. Mouthfeel is used to describe a much broader range of characteristics and textures.
Bourbon
Bourbon, along with Typica, are main Coffea Arabica cultivars. Bourbon was developed by the Roasted Coffee Pictorial Guide. ">French on the island of Bourbon, now Reunion, in the India Ocean near Africa. The seeds were sold to the French by the British East India Company from Aden, Yemen, and were planted in 1708. After generations, it began to express unique characteristics and became more robust. Bourbon has slightly higher yields and is more robust than Typica in general. It has a broader leaf and rounder cherry (and green bean) than Typica, a conical tree form, and erect branches. It has many local variants and sub-types, including Tekisic, Jackson, Arusha, and the Kenya SL types. In general, Bourbon can have excellent cup character. The cherry ripens quickly, but is at risk from wind and hard rain. It is susceptible to major coffee diseases. Bourbon grows best at altitudes between 1100 - 2000 MASL. Bourbon coffees should have green tips (new leaves) whereas Typicas should have bronze-to-copper tips.
Bourbon Mayaguez
A Bourbon cultivar variant from Rwanda and Burundi, from the early part of the 20th century. Bourbon coffees are named for the island in the India Ocean where French colonists grew it.
Brightness
A euphemistic term to describe acidity in coffee. A bright coffee has more high, acidic notes. Not to be confused with the brighter roast flavors of light roast levels, such as City to City+ roasts. Read more about acidity to understand its use as a flavor term, not in reference to the quantity of acidity in coffee.
Catimor
Catimor is a broad group of cultivars derived from HdT (Hibrido de Timor) and Caturra cross, highly productive, sometimes with inferior cup flavor. The main issue is the Robusta content in HdT, although this has given Catimor types some resistance to Coffee Berry Disease, and Rust (CLR), and in some cases to Nematodes. One issue is that Catimor is over-bearing, requires much fertilizer input, and might "wear itself out" in a short time span (5-10 years). The first research in this cross was at CIFC in Portugal in the late '60s, tested in Angola and Brazil. It was introduced in the 1980s in multiple places, one of the first being the Variedad Colombia released in 1985. Based on Brazilian and Portuguese types, IHCAFE 90 and IHCAFE 95 (Costa Rica 95) were widely planted. Honduras has Lempira, El Salvador has Catisic, Nicaragua has Catrenic. Cauvery was developed in India from plant material direct from Portugal. Indonesia is widely planted in Catimor types, such as Ateng, the main benefit being this resistance to Coffee Leaf Rust.
Catuai
Catuai is a high-yield Arabica cultivar resulting from a cross of Mundo Novo and Caturra. The tree is short, with lateral branches forming close angles to the primary branches. It is robust and can tolerate areas with strong winds or rain. Catuai requires fertilization and care. It was developed by the Instituto Agronomico do Campinas in Brazil in the '50s and '60s, and is widely used in Brazil and Central America. There are yellow-fruited and red-fruited types, and many selections. In 2000, a new type called Ouro Verde was released with more vigor than Red Catuai.
Caturra
Caturra is an Arabica cultivar discovered as a natural mutant of Bourbon in Brazil in 1937. It has a good yield potential, but was not ideal for Brazil growing conditions (due to lack of hardness and too much fruit in 3-4 production cycles). However, it flourished in Colombia and Central America and had good cup characteristics, possibly displaying citrus qualities. At higher altitudes quality increases, but production decreases, and it sometimes requires extensive care and fertilization. It has good cup quality, and perhaps shows a more citric acidity, and lighter body than Bourbon.
City Roast
City roast is what we define as the earliest palatable stage that the roast process can be stopped and result in good quality coffee. City roast occurs roughly between 415 and 425 degrees Fahrenheit in many coffee roasters with a responsive bean probe where First Crack starts in the 395 to 405 degree range. The benefits of City roasts are that the origin flavor of the coffee is not eclipsed by the development of strong roast flavors, but the risk is that sourness, astringency, or under-developed sweetness makes the cup unpleasant. City roast generally has a light brown color with strong surface texture, even dark creases in the bean surface, and only moderate expansion of the bean size. This varies greatly in different coffees though. As a very general rule, to reach City roast the coffee is removed from heat at the last detectable sound of First Crack, or very soon after, with no further development toward 2nd crack.
City+ Roast
City+ roast is an ideal roast level that occurs roughly between 425 and 435 degrees Fahrenheit in many coffee roasters with a responsive bean probe where First Crack starts in the 395 to 405 degree range. Also called a medium roast. This range of roast temperatures is after City roast (hence the + !) and indicates that the coffee has been allowed to develop further, anywhere from 10 seconds to 1 minute or more depending on roast method, after the last "pop" of First Crack was heard. These times and heat ranges vary greatly depending on the roast machine and green coffee. The benefits of City+ roasts is the balance between moderate roast flavor and the origin flavor of the green bean; astringent, sour or "baked" light roast flavors are reduced, yet the flavors specific to a particular coffee lot are still expressed in the cup flavor. City+ has a brown color and may not yet have the smooth surface that comes as further browning and bean expansion occur as the coffee approaches 2nd crack.
Dry Fragrance
In the cupping procedure for tasting and scoring coffee, this is the smell of the dry ground coffee before hot water is added. The term fragrance is used since it is normally applied to things we smell but do not consume (perfume, for example), whereas aroma is usually applied to foods and beverages.
Dry Process
Dry process is a method to transform coffee from the fruit of the coffee tree to the green coffee bean, ready for export. Dry processing is the original method, and the wet process was devised later (as well as the very recent pulp natural process). It is a simple method, using less machinery and more hand labor, and has been a tradition in some growing origins for centuries. It risks tainting the coffee with defect flavors due to poor handling, drying, or ineffective hand-sorting. In dry processing the fruit is picked from the tree and dried directly in the sun or on raised screens, without peeling the skin, or any water-based sorting or fermenting. The dried coffee turns to a hard, dark brown pod, and the green seed is torn out from the skin and parchment layers in one step, or pounded out by hand. Because there is no chance to skim off floating defects, or removed under-ripes as with the wet process, most defects must be removed visually, by hand. Dry process coffees generally have more body and lower acidity than their wet process counterparts, with more rustic flavors due to the long contact between the drying fruit and the seed. They also can have more defects, taints, and lack of uniformity both in the roast and in cupping. A dry process coffee is sometimes referred to as natural coffee, full natural, or traditional dry process, or abbreviated DP.
First Crack
First crack in one of two distinct heat-induced pyrolytic reactions in coffee. It is distinguished by a cracking or popping sound in the coffee, and occurs between 390 and 410 degrees Fahrenheit in most coffee roasters. It has a sound more similar to the popping of popcorn, whereas the Second Crack that occurs around 440 to 450 Fahrenheit has a more shallow, rapid sound, like the snapping of Rice Krispies cereal in milk! First crack involves a rapid expansion of the coffee seed, and marks the point where water and carbon dioxide fracture, leading to the liberation of moisture from the coffee in the form of steam. First crack opens the crease in the bean enough to release remaining silverskin, or chaff. First crack is a clue to the roaster-operator about the roast level, and it's termination generally marks the first stage (City Roast) where coffee is acceptably dark enough to enjoy.
Flavor
This is the overall impression in the mouth, including the above ratings as well as tastes that come from the roast. There are 5 "Primary Tastes" groupings (Sour, Sweet ,Salty, Bitter, Savory (Umami) and many "Secondary Tastes," as you can see on the Tasters Flavor Wheel. As the primary category in taste evaluation (what coffee would you want to drink that smelled good and tasted awful?) it is of great importance. But in a sense the flavor impression is divided between this score AND the Finish/ Aftertaste score.
French Mission Bourbon
French Missionaries brought the original coffee to East Africa, from Reunion island to Tanzania, then Kenya. There are still areas with original Bourbon rather than the SL varieties. This Bourbon appears to have Mokka inputs as well, since coffee was brought directly from Aden, Yemen to northern Tanzania (Tanganyika) by French fathers, and the two naturally mutated into what was called French Mission coffee.
French Roast
Sugars are heavily caramelized (read as burned) and are degraded; the woody bean structure is carbonizing, the seed continues to expand and loose mass, the body of the resulting cup will be thinner/lighter as the aromatic compounds, oils, and soluble solids are being burned out of the coffee and rising up to fill your house with smoke. 474 is well beyond any roast I do on the Probat. Second crack is well finished. I will go as high as 465 on a couple blends, and that's my limit.
Full City Roast
A coffee that has been roasted to the brink of second crack. The internal bean temperature that second crack normally occurs at is 446 degrees F. But in fact second crack is a little less predictable than first crack, in my experience. Why? It could be explained as this: first crack is the physical expansion of the coffee seed as water and carbon dioxide split and CO-2 outgassing occurs. Second Crack is the physical fracturing of the cellular matrix of the coffee. This matrix is wood, also called cellulose, and consists of organized cellulose that reacts readily to heat, and not-so-organized cellulose that does not. Since every coffee is physically different in size and density due to the cultivar, origin, altitude, etc. it might make sense that the particular cell matrix is different too, and not as universally consistent in reactiveness as H-2O and CO-2.
Roasted Coffee Pictorial Guide. ">Full City+ Roast
A roast slightly darker than Full City. At Full City+, the roast is terminated after the first few snaps of second crack. The main cue that distinguishes the difference between the Full City (or FC) and Full City + is audible, not visual.
Gesha
Gesha (often wishfully misspelled as Geisha) is a long-bean Ethiopia cultivar selection with unique cup character. It is most famously grown on the Jaramillo plot at Hacienda Esmeralda in Panama by the Peterson family. It has now been broadly planted in other Central America countries and beyond to capitalize on the high price it has fetched. It was distributed from the garden at CATIE in Costa Rica, and displayed some rust-resistant properties. Gesha is a town in Western Ethiopia.
GrainPro SuperGrain Bag
A multi-layer plastic bag with a gas barrier enabling coffee "to build up a modified atmosphere, similar to the principle of the Cocoon" (quoted from the GrainPro literature). The bags can be used with any kind of commodity, and in tests using coffee, the bags have been shown to extend the flavor life of the coffee. We started using them extensively in 2008 to store delicate coffees and have found them to work very well. It means that we can buy more coffee at the peak of the season, when the best coffee is available, and then hold it in GrainPro for a few months with no flavor loss. These bags are for resealable safe storage of dry commodities. The bags act as a gas and moisture-proof barrier which guards against the ingress of water vapor, while retaining low Oxygen and Carbon-Dioxide levels created by the respiration of the commodity. They are made of tough, multi-layer plastic with gas barrier between layers of PE 0.078mm thick material. They are sealed using tie-wraps and placed inside the large jute bags of coffee in our warehouse.
Hibrido de Timor
Hibrido de Timor is a cross between Robusta and Timor Arabica, abbreviated HdT. It was a source plant for Catimor cultivar, and has excellent resistance to the widespread fungal problem, Coffee Leaf Rust (CLR). In Indonesia it is sometimes called TimTim. It was first collected in See our Timor Coffee Offerings for more information.">East Timor in 1978 planted in Aceh in 1979, and in Flores 1980 where the variety is called Churia.
Icatu
Icatu is a cultivar that originated in Brazil, has high production and good disease resistance. It has robusta inputs, but has been back-crossed with arabica cultivars to improve cup quality. It has 30-50% more cherry than Mundo Novo, a tall tree form, and red- and yellow- fruited progenies. It was released in 1993 by the IAC in Campinas Brazil.
Jackson
A Bourbon cultivar variant from Rwanda and Burundi. Bourbon coffees are named for the island in the India Ocean where French colonists grew it.
Java Cultivar
Java Cultivar is planted widely in Cameroon, related to Abyssinia found in East Java. It is distinct from Java Typica types, such as Bergendal, Pasumah or BLP, and from Jamaique Typica in Cameroon as well. It has resistance to CBD and due to it's vigor can recover from CLR. The fruit and seed are elongated and the tips are bronze-colored.
Jamaica Blue Mountain
JBM is short for Jamaica Blue Mountain, which is both a trade name for certain Jamaica coffee, and a Typica cultivar. As a cultivar, it is one of the older New World Typica types since the Typica was circulated around the Carribean isles long before it was planted in the mainland of Central America. Not all Jamaica-grown coffee is necessarily JBM cultivar. As a trade name, it supposedly signifies the higher grown coffee from Jamaica, as opposed to Jamaica High Mountain, which is lower grown (!). There is no blue shade to the coffee or the mountain, or a specific geographical designation it indicates.
Kent
Kent was the first useful CLR resistant cultivar; it was developed on the Kent estate in Mysore, India. Kent was widely planted but eventually was destroyed by a new wave of CLR, Coffee Leaf Rust fungus.
Kona Typica
Kona is a special cultivar, Kona Typica, a traditional varietal that cannot be grown at low elevations.
Mandheling
A trade name used for wet-hulled Sumatra coffees. It is an area and a culture group as well (spelled Mandailing often) but there is little coffee production in this area anymore. Mandheling coffees might have originated from anywhere in North Sumatra or Aceh provinces. They are graded on flavor defects in a very loose way, so a "Grade One" Mandheling might, in fact, have many physical defects.
Maracatu
As the name indicates cross between large-bean Maragogype and Caturra cultivars. It has a larger than average bean and interesting cup flavors, similar to Pacamara.
Maragogype
Maragogype is a mutation of Typica coffee and was discovered in Brazil. The Maragogype is a large plant with big leaves, low production and very large fruits (and seeds / green beans). It has been called the "Elephant Bean coffee." Maragogype adapts best between 2,000-2,500 feet. The mild cup characteristics and bean size were historically sought-after in Europe.
Mibirizi
A Bourbon cultivar variant from Rwanda and Burundi. Bourbon coffees are named for the island in the India Ocean where French colonists grew it.
Mokha
Mokha Yemeni type of coffee, both in terms of the family of cultivars planted there, and the general trade name. The alternate spellings are Mocca, Moka, Mocha. The name refers to the former coffee port on the Red Sea called Al Mahka, and all the spellings are derived from a phonetic interpretation of the Arabic pronunciation for this town. It is no longer a coffee port, and most Yemeni coffee ships from Hodeidah, also on the Red Sea. In terms of cultivar, all types of Mokha coffee are proved to come from Harar, Ethiopia or other areas on the Eastern side of the Rift Valley. Yemeni Mokha coffee is the first commercially planted "farms" (the coffee is grown on stone walled terraces) and the souce for what would become Typica and Bourbon cultivars. So all coffee comes from West Ethiopia and the Boma plateau of Sudan, then to Eastern Ethiopia and Harar via the slave trade route, then to Yemen, then to the rest of the world. Moka is an established cultivar as well, found in many ICO coffee research gardens and grown in some locales (such as Maui, Hawaii).
Mouthfeel
A major component in the flavor profile of a coffee, it is a tactile sensation in the mouth used in cupping. quite literally can refer to how a coffee feels in the mouth or its apparent texture. In cupping mouthfeel is scored at light City roast level but mouthfeel can be directly affected in other ways by roast level as well, brew strength, and proper resting of the coffee after roasting. That is, Espresso and Dark Roast coffees have noticeably different mouthfeel than the same coffees at lighter levels. Body is synonymous with mouthfeel, but the latter implies a wider range of possible qualities, whereas body traditionally implies viscosity only. Mouthfeel is perceived by the trigemenal receptors, nerve fibers that surround taste buds.
Mundo Novo
Mundo Novo is a commercial coffee cultivar; a natural hybrid between Typica and Bourbon, originally grown in Brazil. Be aware that when many farmers and brokers refer to Brazilian Bourbon coffees, they might mean Mundo Novo. It has a rounded seed form. The plant is strong and resistant to disease. Mundo Novo has a high production, but matures slightly later than other kinds of coffee. It does well between 1000-1200 MASL, which suits Brazil coffee altitudes, with an annual rainfall of 1,200-1,800 mm.
Nitrogen Flushing
Pushing nitrogen, an unreactive gas, into a bag of coffee to force out oxygen, which is more reactive. Nitrogen flushing is often done as part of vacuum packaging, since vacuuming out oxygen is not sufficient to remove all oxygen in a bag.
Onan Ganjang
Onan Ganjang is a locality in North Sumatra within the greater "Lintong" growing area, as well as a local cultivar. The coffee from the area took on unique characteristics over time but the original heredity of the plant is not known.
Pacamara
As the name implies, Pacamara is a large bean cultivar, a cross between Pacas and Maragogype with unique flavor properties. This variant originated in El Salvador in 1958, and has spread to nearby Central American countries, but is still chiefly grown in El Salvador. It has unique flavors that range from chocolate and fruit, to herbal or, in the worse coffees, vegetal (green onion specifically).
Pacas
Pacas is a natural mutation of Bourbon cultivar that appeared in El Savador in 1949. It has good cup character, and is an input into Pacamara cultivar as well. Caturra and Villa Sarchi are also natural dwarf Bourbon mutations.
Pache
Pache is a dwarf mutation of Typica coffee first observed at Finca El Brito, Guatemala. It is also called Pache Comun. A varitety called Pache Colis is a cross of Caturra and Pache Comun, and is extremely short in form.
Pulp Natural
Pulp natural is a hybrid method of processing coffee to transform it from the tree fruit to a green bean, ready for export. Specifically, it involves the removal of the skin from the coffee, like the first step of the wet process, but instead of fermenting and removing the fruity mucilage, the coffee is dried with the fruit clinging to the parchment layer. Pulp natural can be performed with a traditional pulper, or with newer forced demucilage equipment, which allows for greater control of exactly how much mucilage is left to dry on the coffee. Pulp natural coffees tend to have more body and less acidity than their wet process equivalents, and can have a cleaner, more uniform quality than full natural dry-process coffees.
Rambung
An Ethiopia cultivar brought to Java in 1928, along with a type called Abyssinia.
Robusta
Robusta usually refers to Coffea Robusta, responsible for roughly 25% of the world's commercial coffee. Taxonomy of Robusta is debated: some sources use “Robusta” to refer to any variety of Coffea Canephora, and some use "Robusta” as a species name. Caffeine content of Robusta beans is about twice that of Arabica. Robusta can be used in espresso blending to increase body and crema content.
Ruiru 11
Ruiru 11 is named for the station at Ruiru, Kenya where it was developed in the '70s and released in 1986. The initial test were with Hibrido de Timor (a cross between Arabica and Robusta, resistant to Coffee Leaf Rust) and Rume Sudan, an original coffee strain resistant to CBD, Coffee Berry Disease. Later they added SL-28 and SL-34 imputs due to poor cup character of the early tests. The Robusta content of Ruiru 11 is still an issue, and the cup does not match the quality of the SL types.
Second Crack
Second Crack is the second audible clue the roaster-operator receives about the degree-of-roast, following First Crack. Whereas First Crack sounds a bit like popcorn popping, Second Crack has a faster, shallower patter, much like Rice Krispies in milk, electrical sparking, a snapping sound. Second crack is a further stage of the pyrolytic conversion of compounds in coffee and occurs around 440 to 450 degrees Fahrenheit. The 2nd crack is a physical fracturing of the cellular matrix of the coffee, and results in an eventual migration of oils to the outside of the bean, as they are freed from their chambers within the coffee. When second crack is volitile, it can blow small discs off the coffee bean.
Semi-washer
Semi-washed has been used, most commonly in Brazil, to describe a hybrid coffee process. But it is uncertain if the term always indicates the same method. Semi-washed coffees are also very common in Sumatra, where they are called Giling Basah. Semi-washed coffees are best described as "wet-hulled", and will have more body and often more of the "character" that makes Indonesians so appealing and slightly funky. In this process, the parchment coffee (the green seed with the parchment shell still attached) is very marginally dried, then stripped of the outer layer, revealing a white-colored, swollen green bean. Then the drying is completed on the patio (or in some cases, on the dirt), and the seed quickly turns to a dark green color.
Sidikalang
Sidikalang is found less and less frequently in Sumatra and other parts of Indonesia. Much of the Typica was lost in the late 1880s, when Coffee Leaf Rust swept through Indonesia. However, both the Bergendal and Sidikalang varieties of Typica can still be found in Sumatra, Sulawesi, and Flores, especially at higher altitudes and in remote areas.
SL-28
Scot Labs selection 28 Kenya cultivar, a preferred type with Bourbon and Mokka heritage. It supposedly is selected from Tanganyika DR cultivar, found by A.D. Trench on a trip through Tanzania, and has similar drought resistant properties. DR is of French Mission Bourbon origin. Many prefer SL-28 to the other successful, widely used cultivar, SL-34.
SL-34
Scott Labs selection 34 Kenya cultivar, a preferred type with French Mission Bourbon heritage. It supposedly is selected from French Mission Bourbon trees at Loresho Estate in Kabete Kenya. SL types are responsible for 90% of Kenya coffees. SL_34 has better yields than SL-28, and is grown at lower altitudes than SL-28.
Tekisic
Tekisic is a Bourbon cultivar variant still grown in El Salvador. Bourbon coffees are named for the island in the India Ocean where French colonists grew it.
Typica
ypica is one of the main cultivars of Coffea Arabica, and one from which many other commercial types have been derived. It has a longer seed form than the other main cultivar, Bourbon. Typica coffee plants are tall and have a conical shape with branches that grow at a slight slant. It has a rangey, open form. The lateral branches form 50-70° angles with the vertical stem. It has fairly low production and good cup quality. C. Arabica Var. Typica is sometimes expressed as C. Arabica Var. Arabica as a group that contains Typica ... confusing. The issue is that "Typical Arabica" indicates the common form, as well as the original form, so when the Scottish Mission brought arabica from Yemen direct to Kikuyu Kenya from Yemen, that was Typica (with dark bronze tips - new leaf) and when Kona Hawaii was replanted that was Typica from Guatemala, with bronze tips, but over so much time and geography, these two Typicas would hardly be the same. Typica has a host of sub-types, from Blue Mountain to Bergendal, Java Typica to Guatemala Typica. All should have dark tips. Typica was the first coffee in the New World; Java-grown plants were a gift from the Dutch to Louis XIV, were cultivated in Parisian gardens, then thousands of seedlings were sent to the French colony in Martinique in 1720.
Villa Sarchi
An arabica cultivar that is a natural dwarf mutation of Bourbon, and in that way is similar to Caturra (as well as Pacas).
Villalobos
A natural dwarf mutation of Typica, found mostly in Costa Rica.
Wet Aroma
In cupping, wet aroma refers to the smell of wet coffee grinds, after hot water is added. The aromatics of a coffee greatly influence it's flavor profile, and comes from the perception of the gases released by brewed coffee. Aroma is greatest in the middle roasts and is quickly overtaken by carbony smells in darker roasts. Aroma is distinct from the dry fragrance from the coffee grounds; in general fragrance describes things we do not eat (like perfume) and aroma pertains to food and beverage we consume. Aromatics as a term may encompass the entire aroma experience of a coffee. Aromatics are a huge part of flavor perception (remember the 'hold your nose and eat an onion experiment). Aromatics reach the olfactory bulb through the nose and "retro-nasaly" through the opening in the back of our palate. While some taste is sapid, perceived through the tongue and palate via papillae, or taste buds, most of flavor quality is perceived through the olfactory bulb.
Wet-hulled Process
Wet-hulled process is a hybrid coffee method used in parts of Indonesia, especially Sumatra. It results in a dark, opal-green coffee with little silverskin clinging to it, and a particular low-acid, earthy, heavy body flavor profile. In this method, the farmer picks ripe coffee cherry, pulps off the skin and either dries it immediately for one day, or lets it sit overnight in a bucket (with our without water), then washes it the next day and dries it. In either case, the coffee is partially dried with some or all of the mucilage clinging to the parchment-covered seed. It is then sold at a local market to a coffee processor. They receive coffee at 40-50% mositure content, then dry it to 25-30%, and run it though the wet-hull machine. Friction strips off the parchment, and the bean emerges swollen and whitish-green. Then it is dried on the patio down to 11-14% moisture, ready for sorting, grading, bagging and export. In Bahasa, the method is called Giling Basah.
Wet Process
Wet-process coffee (or washed coffee) is a method to transform the fruit from the tree into a green coffee bean for roasting. This process uses water at the wet mill to transport the seed through the process, allowing for the removal of defects that float to the surface. In traditional wet-processing, the wet mill is where the coffee is pulped (the outer fruit skin removed), floated in water (to remove defective beans), fermented (to break down the fruit mucilage layer), washed (to remove the fruit) and dried on a patio, a screen (raised bed), or a mechanical dryer. At this point green coffee seed is inside an outer parchment shell, rested for a period of time (reposo) then milled at the dry mill into the green bean. Wet processing often produces a brighter, cleaner flavor profile, with lighter body than dry process coffees or the hybrid pulp natural process. Wet process coffees are referred to also as washed coffees, or fully washed.
Yellow Bourbon
Yellow Bourbon is a sub-type that has fruit which ripens to a yellow color, found mainly in Brazil where it was first grown. Bourbon coffees are named for the island in the India Ocean where French colonists grew it. It is possible that Yellow Bourbon is a natural mutation of a cross between Bourbon and a yellow-fruited Typica called "Amarelo de Botocatu."
