Coffee Classification and Flavor Characteristics_ Benefits of Common Coffee Varieties and Prices with Pictures

Coffee is one of the most varied agricultural products in the world, and the differences between varieties shape everything from the price on the shelf to the flavors in your cup. This guide walks through the main coffee species and the mutations and hybrids that grew out of them.

The Rise of Coffee Culture

In an era of sophisticated lifestyle and ritualistic living, coffee culture has become part of daily life, and whole coffee beans are gradually becoming familiar to the public. Whether it is instant coffee or premium beans, both are made from the seeds of fruit harvested from coffee trees. Before roasting, coffee beans are called green beans. There are many types of green beans, and their flavors vary with the coffee variety and the geographical environment where the trees grow. Like grapes, strawberries, and other fruits, their tastes differ greatly according to variety and growing conditions.

Coffee Tree Varieties

There are over 500 species of coffee trees with 6000 varieties, most of them tropical trees and shrubs. Four main coffee trees exist in the world, but only two have significant commercial value and are widely cultivated, with their beans surpassing the others in quality.

The first is Arabica. World-renowned FrontStreet Coffee Blue Mountain Coffee, FrontStreet Coffee Yemen Mocha Coffee, and others are almost all of the Arabica variety. The other is Robusta, which originates from Congo in Africa. Different varieties of beans have different flavors, but even with the same variety of tree, different soil and climate give the beans produced their own unique character. The other two are Liberica and Excelsa.

Biologically speaking, coffee varieties can be divided into Arabica, Robusta, and Liberica. The main varieties consumed worldwide are Arabica and Robusta, while Liberica is often overlooked because of limited production or inferior quality.

Generally, Arabica is used mainly for single-origin or specialty coffee, while Robusta goes into instant coffee. Although Arabica can be defined as premium and Robusta as secondary, that classification is not really necessary, and it is better to choose based on personal taste. From a flavor perspective, the United States and Japan tend to prefer lighter coffee brewed from Arabica, while Europe favors espresso made from a blend of Arabica and Robusta.

Arabica: Premium Coffee Beans with Exceptional Flavor and Aroma

Arabica is a representative variety originating from Ethiopia, also produced in South Africa, other African countries, and Asia, accounting for 70-75% of the world's coffee production. Arabica has weak resistance to pests and diseases, which makes highland regions more suitable for cultivation. Arabica beans grown above 1500 meters have the best quality.

The high quality that comes from such painstaking effort, with balanced flavor, mouthfeel, and aroma, can be certified as premium coffee beans, used mainly for single-origin or specialty coffee. The three famous beans, FrontStreet Coffee Hawaii Kona, FrontStreet Coffee Jamaica Blue Mountain, and FrontStreet Coffee Yemen Mocha, all belong to the Arabica variety. Arabica green beans have a dark, narrow appearance and are hailed as the highest-quality highland Arabica variety, characterized by rich flavors including sweetness, acidity, and aroma.

Robusta: Strong Acidity with Rich Body

Robusta originates from Congo in Africa and accounts for 30% of the world's coffee production. The word "Robusta" means "robust," and indeed this tree has strong resistance to pests and diseases and can survive in almost any soil, even growing wild. It can be cultivated in high-temperature regions, grows quickly, and is easy to farm, which gives it the advantage of a low price. It is used mainly for blending or as the base of instant coffee. Some Robusta produced in India, Africa, and Brazil has strong acidity, high caffeine content, and a richer body.

Recently there is also the Arabusta variety, a crossbreed with Arabica that offers a superior taste and aroma.

Robusta has a plump, oval appearance, with raw beans showing light brown or yellowish-brown with grass-green and yellow luster. Compared with Arabica, it has a more fragrant but lighter taste, marked by inconspicuous acidity and stronger bitterness.

Excelsa Coffee Variety

Excelsa is a variety discovered in 1904, originating from the Charlie River region of Africa. It produces small fruits with high single-tree yields, and it is notably drought-resistant. The product has a strong aromatic flavor with a slightly bitter taste, and it is cultivated only in limited quantities.

Typica Coffee Variety

Typica is the oldest native variety of Ethiopia, from which all Arabica varieties are derived. Typica has bronze-colored top leaves and oval or slender-pointed beans. It has an elegant flavor but a weak constitution, poor disease resistance, and low fruit yield. FrontStreet Coffee Jamaica Blue Mountain, FrontStreet Coffee Indonesia Sumatra Mandheling, and FrontStreet Coffee Hawaii Kona are all excellent estate beans belonging to Typica. Those bronze-colored top leaves are one of Typica's characteristic features.

Typica green beans have slightly upturned ends, an oval shape, and appear thin when viewed from the side. Even when cultivated at different altitudes, the thickness variation on the side of the green beans remains minimal.

Genetic Mutations - Typica Variants

Typica Variant - FrontStreet Coffee Indonesia Sumatra Mandheling

Indonesia's main coffee-producing regions include Sumatra, Java, and Sulawesi, with Mandheling from Sumatra being the most famous.

Mandheling is also known as "Sumatra coffee." Coffee from Lake Tawar in the north can be called Aceh Coffee or Lake Tawar Coffee, while the Lintong and Lake Toba areas can be called Mandheling.

FrontStreet Coffee Mandheling has a strong flavor with a rich body and vibrant, lively character. It is neither astringent nor acidic, with its body and bitterness fully expressed. FrontStreet Coffee Mandheling beans may have the ugliest appearance, but enthusiasts say that the less attractive Sumatra beans look, the better, richer, and smoother they taste.

We have collected four types of Mandheling:

FrontStreet Coffee Gold Mandheling

FrontStreet Coffee Ma Mian Mandheling (Timtim Mandheling long berry), Sumatra, Mandheling Longberry, Timtim Belangele

FrontStreet Coffee Lintong Mandheling Grade-1

FrontStreet Coffee Emerald Mandheling (Sumatra Aceh)

TimTim -

This is Timor Hybrid, meaning a hybrid of Arabica and Robusta. The familiar Catimor variety is created by further hybridizing with it.

Tim Tim - FrontStreet Coffee Ma Mian Mandheling longberry

Tim Tim is a bean from Indonesia. Because of its long shape, many people call it horse face bean, while others call it long Mandheling. In fact, Tim Tim is not a pure variety but a natural hybrid of Arabica and Robusta trees. This variety was discovered on Timor Island in the 1940s and was cultivated for its natural disease resistance. In America it is called Hybrido de Timor, abbreviated Tim Tim. In Indonesia it is also known as Bor Bor.

Typica Variant - FrontStreet Coffee Jamaica Blue Mountain

FrontStreet Coffee Jamaica Blue Mountain: globally popular, the hard-to-find Blue Mountain comes from the Typica family.

The history of Jamaican coffee can be traced back to the 18th century, when the British introduced coffee trees to Jamaica and planted them in the Blue Mountain range. These are further divided into high-altitude Jamaica Blue Mountain Coffee, Jamaica High Mountain Coffee, and Jamaica Coffee, with different grades determining different prices.

Jamaica Blue Mountain Coffee

Blue Mountain Coffee and High Mountain Coffee are each divided into four grades. From top to bottom by quality: NO.1, NO.2, NO.3, and PB (Peaberry). According to CIB standards, only coffee grown above 666 meters is called Jamaica Blue Mountain Coffee.

Jamaica High Mountain Coffee

Coffee produced below 666 meters in the Blue Mountain region is called High Mountain Coffee. It is second only to Blue Mountain Coffee in quality and is known in the industry as the brother variety to Blue Mountain. Because the production of Jamaica Blue Mountain Coffee is extremely limited, Jamaica High Mountain Coffee is the best choice if you want to taste the Jamaican style.

Jamaica Coffee

Coffee grown outside the Blue Mountain range is called Jamaica Coffee. Originally, Chinese coffee professionals had a misconception that only coffee grown above 1800 meters in the Blue Mountain area could be called Blue Mountain Coffee. In fact, on the mountain crown above 1800 meters of the range there is only one estate: Amber, owned by a person of Chinese descent with the surname Lyn (Lin), whose ancestors came from Guangdong, China. The estate has only 30 hectares of land with very limited production. Blue Mountain Coffee is mainly distributed across five mountainous areas: John Crow, St. John's Peak, Mossman's Peak, High Peak, and Blue Mountain Peak.

Typica Variant - FrontStreet Coffee Hawaii Kona

Kona: although grown at only a few hundred meters of altitude, Kona from the Big Island of Hawaii enjoys gentle sea breezes and fertile volcanic soil, giving it exceptionally clean acidity and sweetness. It even surpasses the higher-altitude FrontStreet Coffee Jamaica Blue Mountain Coffee.

Typica Variant - Maragogype

Maragogype: a mutant of Typica, with very large, long fruits that are somewhat twisted, and plants with long internodes and large leaves. Yield is relatively low.

It was first discovered in 1870 in the Maragogype coffee-producing area of Bahia state, northeastern Brazil. The beans are at least three times larger than regular Arabica, hence the name. Maragogype has poor flavor at low altitudes but better flavor at high altitudes, with mild acidity and a pleasant sweet aroma. (Maragogype shown on the left.)

Typica Variant - Pacamara

Pacamara: a hybrid of Pacas and Maragogype, with beans second only to Maragogype in size. It is an excellent variety developed in El Salvador in the 1950s and has achieved good cupping scores in recent years.

Typica Variant - Kent

Kent: a Typica hybrid discovered in India with high yield and strong disease resistance, but it has never achieved good cupping scores.

Bourbon Coffee

Bourbon: an early variant of Typica, dating to before recorded coffee history, after Typica was transplanted to Yemen, with the bean shape changing from slender-pointed to round. In 1715, the French transplanted round beans from Yemen Mocha to Bourbon Island on the east coast of Africa, renamed Reunion Island after the French Revolution, and the variety took the name Bourbon. Bourbon round beans were indirectly passed to Brazil and Central and South America in 1727. In 1732, the British also transplanted Yemen Mocha to St. Helena Island, later where Napoleon was imprisoned, also as Bourbon round beans. Bourbon is the perennial champion in American specialty coffee cupping competitions.

The Bourbon variety is a subspecies produced by Typica mutation, belonging, along with Typica, to the oldest existing coffee varieties. When green fruits mature, they turn bright red.

Genetic Mutations - Bourbon Variants

Bourbon Coffee - Red Bourbon

After coffee trees flower and fruit, the color change of the coffee fruits is green, then slight yellow, slight orange, mature red, and finally darker red when fully ripe, which is why some call it "Red Bourbon." In fact, Red Bourbon is what we generally call the Bourbon variety. Bourbon grown at high altitudes usually has better aroma, brighter acidity, and flavors that can even resemble red wine.

Simply put, Bourbon is a coffee tree variety belonging to a branch of Arabica. It generally produces red fruits, called Red Bourbon. Besides this, there are also Yellow Bourbon and Orange Bourbon. Yellow Bourbon has a relatively lower yield but better quality.

Bourbon Coffee - Yellow Bourbon

Yellow Bourbon is a hybrid of Bourbon with other varieties. Because of its lower yield and weaker resistance to wind and rain, it has not been widely cultivated. Grown in high-altitude areas, however, it shows excellent flavor and has become more common in recent years. Yellow Bourbon, with yellow fruits when ripe, was first discovered in Brazil and now grows mainly there. It is generally believed to be a mutation from a cross between red-fruited Bourbon and a Typica variant called "Amerelo de Botocatu" that produces yellow fruits.

[FrontStreet Coffee Brazil Queen Estate Semi-washed Yellow Bourbon] Flavor characteristics: sweet and smooth fruit sweetness, obvious nutty flavors, balanced and gentle acidity, weak and clean bitterness, with rich chocolate aroma and nutty flavors, and a bright, refreshing mouthfeel.

Bourbon Coffee - Pink Bourbon

Pink Bourbon, as its name suggests, has romantic pink coffee cherries when ripe. It is a very rare new variety, cultivated by hybridizing Red Bourbon and Yellow Bourbon. Pink Bourbon is considered rare mainly because maintaining that beautiful pink color is extremely difficult. Sometimes orange Bourbon is harvested instead, because the final color of the fruit is determined by recessive genes in the pollen grains. Among the selected pollen grains used for hybridization, there are both yellow genes leaning toward Yellow Bourbon and red genes leaning toward Red Bourbon, and these are all recessive genes that easily interfere with each other.

Currently, Pink Bourbon can be found in Colombia and Guatemala. Taking this batch of FrontStreet Coffee Colombia Pink Bourbon as an example, there are about 1800 coffee trees, with each tree producing approximately 1.8kg of fresh fruit per harvest season. After pulp removal, about 0.36kg of coffee beans is obtained. In a normal harvest season, the total production of this coffee is less than 650kg.

[FrontStreet Coffee Colombia Pink Bourbon] Flavor characteristics: sweet orange, sugarcane sweetness, a pleasant juice sensation, small tomato.

Bourbon Variant - Bourbon Pointu

Bourbon Pointu: discovered on Bourbon Island in 1810, with the bean shape changing from round to pointed, and a caffeine content only half that of regular coffee. Production is low and the plants are weak, making it extremely precious (mostly cultivated in laboratories).

Bourbon Pointu also has two other names, Laurina and Leroy, but neither is as well known as Bourbon Pointu. It is called Pointu Bourbon because the beans are narrow and long with pointed ends, while the original Bourbon, sometimes called Round Bourbon, has shorter beans with slightly oval outlines.

Because of its good flavor and low caffeine content, which has less impact on sleep, Bourbon Pointu was favored by people as early as the 18th century. Many celebrities, including French King Louis XV and the novelist Balzac, were fans. Over the two hundred years from the 18th to the 19th century, Bourbon Pointu was widely cultivated on Bourbon Island, reaching a peak production of 4000 metric tons annually in 1800. A series of disasters followed, though: hurricanes, fire ants, and leaf rust disease, leading to a gradual reduction in cultivation. Finally, in 1942, the last batch shipped back to France was a pitiful 200 kilograms, and after that Bourbon Pointu disappeared without a trace, with even official documents no longer mentioning it. After the 1950s, no one cultivated coffee on Reunion Island, and the island's agriculture shifted entirely to other crops like sugarcane. Coffee was no longer associated with Reunion Island, and Bourbon Pointu was recognized by the industry as "extinct."

The bean disappeared for half a century until it reappeared 8 years ago. On the international market, Bourbon Pointu from its origin on La Reunion Island sells for over 500 yuan per 100 grams. Colombia also began cultivating the bean, and only Camilo Merizalde, the source of beans for multiple WBC champions, dared to take on its transplantation. As a result, this coffee, with a global annual production of only a few tons, commands a premium price.

Flavor description from the archives: bright acidity, blueberry and vanilla notes, velvety smoothness.

Bourbon Variant - SL28, SL34

Kenya's "SL28" and "SL34": direct descendants of Bourbon screened and cultivated by British missionaries and researchers in Kenya in the early 20th century. Over a century they have adapted to Kenya's high-phosphate soil, nurturing the country's characteristic acidic aroma. Top-grade FrontStreet Coffee Kenya coffees all come from these two varieties, but they lose their distinctive character when transplanted elsewhere.

Kenya coffee grades are divided into seven levels based on bean size and into six levels based on taste, from top to bottom. Kenya's best coffee grade is Peaberry (PB), followed by AA++, AA+, AA, AB, and so on. Premium coffee has a bright luster and a delicious taste with a slight wine aroma. In terms of flavor, "Kenya AA" is particularly well regarded.

Grading based on bean size:

Kenya's best coffee grade is Peaberry (PB), followed by AA, AB, and so on.

PB (Peaberry): a grading for small round beans. This refers to coffee fruits with only one seed nucleus instead of the usual two.

AA: a more common grade with larger beans, size above 18 screen, or 7.22 millimeters. These beans usually command the highest prices.

AB: this grade combines A (size 16 screen, or 6.80 millimeters) with B (size 15 screen, or 6.20 millimeters), accounting for about 30% of Kenya's annual coffee production.

Bourbon Variant - Caturra

Caturra: a single-gene mutant of Bourbon discovered in Brazil in the 1950s. Both yield and disease resistance are better than Bourbon's. The plant is shorter, making harvesting convenient. Unfortunately, it shares Bourbon's problem of fruiting one year and resting the next. Its flavor is comparable to, or slightly inferior to, Bourbon beans.

It has stronger adaptability, though, and can be cultivated at high density without shade trees, thriving even when directly exposed to intense sunlight, which is why it is also called "Sun Coffee."

Caturra suits altitudes from a low of 700 meters to a high of 1700 meters, but the higher the altitude, the better the flavor, though yield drops accordingly. There are also yellow Caturra variants in Central and South America, but their reputation is not as good as Yellow Bourbon's.

Bourbon Variant - Catuai

Catuai: a hybrid of Mundo Novo and Caturra, essentially a second-generation hybrid. It inherits Caturra's advantage of a short plant height and compensates for the fragile fruit of Arabica. The fruits are solid and do not easily fall off when exposed to strong winds. The biggest regret is that its overall flavor is somewhat monotonous compared with Caturra.

Catuai also comes in red and yellow fruit varieties, with red fruits winning awards more often than yellow. Catuai, Caturra, Mundo Novo, and Bourbon are the four main coffee varieties in Brazil.

Bourbon Variant - Pacas

Pacas: a Bourbon variant discovered in El Salvador. In 1935, Salvadoran coffee farmer Don Alberto Pacas selected high-yield San Ramon Bourbon varieties to cultivate on his farm. In 1956, his coffee trees produced higher yields than other trees of the same type. University of Florida professor Dr. William Cogwill determined this was a genetic mutation of Bourbon and named it "Pacas."

Pacas has high yield and excellent quality and is quite popular in Central America. Currently, 68% of El Salvador's coffee belongs to Bourbon varieties, with Pacas accounting for 29%. It is similar to Brazil's Caturra and Costa Rica's Villa Sarchi. Today, Pacas makes up about 25% of El Salvador's coffee production. It has high yield and has always been popular. The coffee it produces has a high sweetness similar to Bourbon, but with brighter acidity.

Pacas seedlings

Bourbon Variant - Villa Sarchi

Villa Sarchi: a Bourbon variant first discovered in Costa Rica in the 1960s, frequently appearing on cupping excellence lists in recent years, making it a dark horse with promising prospects. This is a precious variety cultivated by hybridizing Red Bourbon trees. It resists strong winds, prefers high-altitude environments, and possesses excellent acidity with various fruit notes. It has high sweetness, a bright and delicate citrus acidity, and lower raisin and nut aromas, offering high complexity and excellent balance.

It is also a dwarf Bourbon variety, discovered in Sarchi village in Costa Rica's western valleys, suitable for high-altitude organic cultivation. It has lively fruit acidity and an obvious caramel flavor.

Hybrid Variants - Mundo Novo

Mundo Novo: a natural hybrid of Bourbon and Sumatra Typica, first discovered in Brazil. It has high yield and disease resistance, was widely cultivated in Brazil in the 1950s, and was hailed as the new hope of Brazil's coffee industry. However, the trees are tall, making harvesting difficult.

Hybrid Variants - Nicaragua Java

This is the Java variety from Nicaragua, a long-bean variety that is now rare even in Java. It was first successfully cultivated in Nicaragua by Limoncillo Estate. The Java variety originates from the Typica lineage. Java's Typica once suffered a severe leaf rust epidemic that nearly wiped it out. Limoncillo Estate accidentally obtained a bag of seeds, and after planting and raising the seedlings, took the young plants to experts for identification, only to discover it was the Java variety. In 2007, Limoncillo entered the COE with this variety for the first time and surprisingly won second place in Nicaragua's COE that year, with a bidding price even exceeding that year's champion.

Hybrid Variants - Maracaturra

Maracaturra: a hybrid variety cultivated in Guatemala from Maragogype and Caturra, gaining higher recognition after winning first place in Nicaragua's COE in 2009. It combines the rich fruit flavors of Maragogype with the elegant acidity of Caturra, with high body, full floral aromas, and high sweetness.

Arabica Variety - Geisha

Geisha: a derivative variety of the Typica family, exported from Geisha Mountain in southern Ethiopia in 1931 (Geisha has the same pronunciation as the Japanese word "geisha"). It remained obscure in many countries until it was transplanted to Panama in the 1960s, and it began frequently winning cupping competitions starting in 2005.

| Geisha, also called Gesha

Geisha is pronounced the same as the Japanese word "geisha," hence it is also called Geisha coffee. Because the tree is taller than general coffee trees, it was originally planted in a small area within the estate and used as a windbreak.

| Geisha, is a variety

First, the Geisha variety was discovered in the Geisha forest of Ethiopia in 1931 and later sent to the Coffee Research Institute in Kenya. It was introduced to Uganda and Tanzania in 1936; Costa Rica introduced it in 1953.

| Red Label, Green Label, Blue Label

Only Geisha from Hacienda La Esmeralda has the distinction of Red Label, Green Label, and Blue Label:

Red Label (Special-Geisha): brings together the top batches from Hacienda La Esmeralda, all grown above 1600 meters (even higher than 1900 meters), with cupping scores above 90 points;

Green Label (Private Collection-Geisha): Geisha from different plots within Hacienda La Esmeralda, grown at altitudes of 1600-1800 meters;

Blue Label (Geisha 1500): Geisha from Hacienda La Esmeralda, grown above 1500 meters;

| Geisha, unique floral and fruit aromas

Among many coffees, floral aroma and intense tropical fruit sweetness are consistent characteristics of Geisha.

Arabica and Robusta Hybrids (Interspecific Hybrid)

Hybrid Variants - Timor

Timor: a natural hybrid variety discovered in Timor-Leste, an island nation at the eastern end of the Nusa Tenggara archipelago. With 44 chromosomes, it is closer to Arabica. Its flavor is unremarkable, though. Timor has low acidity and lacks distinctive character. Taiwan often uses it as a cost-reducing component in blended beans. Timor-Leste also has high-altitude pure Typica with washed processing. Before buying, be sure to clarify whether it is a hybrid or pure washed Typica, as their quality differs significantly, with the former being mediocre and the latter impressive.

Hybrid Variants - Catimor

Catimor: in 1959, the Portuguese hybridized Brazil's Caturra with Timor, cultivating the second-generation hybrid Catimor with super-strong disease resistance and yield. Its flavor is also inferior, however, making it an important commercial variety today. To improve Catimor's poor reputation in cupping, botanists from various countries have recently returned to multiple rounds of cross-breeding between Arabica and Catimor, attempting to reduce the Robusta lineage.

Hybrid Variants - Icatu

Icatu: a multi-generational hybrid improved variety from Brazil that has reached the top ten of Brazil's Cup of Excellence. In the past, Arabusta, a hybrid of Arabica and Robusta, improved yield and disease resistance but left the coffee flavor poor. Scientists then hybridized Arabusta across multiple generations with Arabica varieties such as Caturra, Mundo Novo, and Bourbon, gradually reducing the undesirable flavors of Robusta while enhancing the aroma and richness of Arabica, thus giving birth to the excellent multi-generational hybrid Icatu.

Hybrid Variants - Ruiru 11

Ruiru 11: a hybrid variety developed by Kenya in 1985 that emphasizes yield over quality. A cross of Arabica and Robusta, to date it cannot be considered specialty coffee. As a result, many suppliers specializing in fresh-roasted specialty coffee do not carry these varieties. Even some imported premium coffee suppliers, however, mix this hybrid into blended coffee to reduce costs. From the genetic mutants above, whether natural or research products, their flavors are greatly related to specific regional conditions.

FrontStreet Coffee Recommendation

Among all the varieties in this guide, Jamaica Blue Mountain remains the benchmark for balance, and FrontStreet Coffee's Jamaica Blue Mountain No. 1 is a fine way to experience it. Drawn from the Clifton Manor estate, which has grown coffee since around 1750, it is the highest grade of Jamaican Blue Mountain coffee, roasted to a medium-dark level so the classic balance comes through clearly: cream, caramel, chocolate, and nuts with a gentle fruit lift, sweet and round in the middle, clean and long on the finish.

Genuine Blue Mountain is scarce by nature. The Blue Mountain range tops out at 2256 meters, and the whole Jamaican Blue Mountain region produces less than 2500 tons a year, a tiny fraction of global output, with Japan historically buying more than 70 percent of it. Every certified bean is packed in traditional wooden barrels, and Jamaica Blue Mountain has been officially exported to China since 2003. FrontStreet Coffee roasts within 5 days and recommends brewing at a 1:15 to 1:16 ratio with 85-88°C water and a medium-coarse grind, a gentle method that lets the cream, caramel, and nut flavors unfold while keeping the soft, bright sweet-tart balance intact.
