Bourbon coffee bourbon species:

Bourbon: a variant of the early (prehistoric coffee) Tibika that changed its shape from thin to round after it was transplanted to Yemen. It was named bourbon in 1715 after France transplanted round beans from Yemeni mocha to the island of Bourbon on the east coast of Africa (renamed Reunion after the French Revolution). Bourbon beans spread to Brazil and Central and South America in 1727, and the British transplanted Yemeni mochas to St. Helena Island (where Napoleon was later imprisoned) in 1732. Bourbon is the winner of the American boutique coffee cup test.

Bourbon, the second species caused by the Typica mutation, is the oldest coffee variety in existence, and the green fruit appears bright red when it is ripe.

Bourbon Coffee Red Bourbon

After the red bourbon general coffee tree blossoms and bears fruit, the color change of the coffee fruit is: green > turn yellowish > turn slightly orange > turn mature red > turn more ripe dark red, so some people also call it [red bourbon], in fact, red bourbon, that is, what we call bourbon species. Bourbon planted at high altitude usually has a better aroma, while the acid is brighter and even tastes like red wine.

Generally speaking, bourbon is a coffee tree that belongs to a branch of Arabica species, generally bearing red fruit, called red bourbon, in addition to yellow bourbon, orange bourbon, yellow bourbon relatively low yield, but better quality.

Bourbon coffee yellow bourbon

On the other hand, the yellow bourbon species is a hybrid between the bourbon species and other varieties. Because of its low yield and relatively intolerant to wind and rain, it has not been widely planted. However, when planted in high altitude areas, it will have excellent flavor performance, which is more common in recent years. Yellow Bourbon, Huang bourbon, the mature consequence is actually yellow, was first found in Brazil, and now mainly grows in Brazil. It is generally thought that it may have been mutated by a cross between a bourbon with red fruit and a variety of iron pickup with yellow fruit called "Amerelo de Botocatu".

Taste characteristics: sweet and smooth fruit sweetness, obvious nutty flavor, balanced and supple acidity, weak and clean bitterness, rich chocolate aroma and nutty flavor, bright and fresh taste.

Bourbon coffee powder bourbon

Pink bourbon, as its name implies, its coffee cherries are romantic pink when ripe. It is a very rare new variety, which is bred by the cross between red bourbon and yellow bourbon. The reason why pink bourbon is rare is that it is difficult to maintain this beautiful pink, sometimes some orange bourbon will be harvested, that is because the color of coffee fruit is ultimately determined by the recessive genes in the pollen grains. Among the pollen grains we selected for hybridization, there are both yellow genes inclined to yellow bourbon and red genes inclined to red bourbon, and these are recessive genes, which are very easy to interfere with each other.

At present, pink bourbon can be seen in Colombia and Guatemala. Take this batch of pink bourbon coffee as an example, there are about 1800 coffee trees. Each tree produces about 1.8kg fresh fruit in the first production season. After peeling and pulp treatment, about 0.36kg coffee beans are obtained. In a normal production season, the output of this batch of coffee is less than 650kg.

Taste characteristics: sweet orange, sweet sugarcane, pleasant juice, small tomato

Bourbon variety pointed body bourbon

Pointed Bourbon (Bourbon Pointu): found in Bourbon Island in 1810, beans changed from round to pointed, with only half the caffeine content, but in small amounts, weak and extremely precious (mostly cultivated in the laboratory).

Bourbon Pointu has two other names, Laurina and Leroy, but neither is as loud as the first name. The reason why it is called sharp bourbon is that the bean shape is long and narrow and both ends are pointed, while the native species bourbon (some call it round bourbon) has a shorter bean body and a slightly oval outline.

Because of its good flavor and low caffeine content (which does not affect sleep), sharp bourbon has been popular as early as the 18th century, with many celebrities, such as French King Louise 15, and the novelist Balzac is a "fan". During the two hundred years of the 19th century, the sharp bourbon was widely planted on the island of bourbon, and its annual production reached a peak of 4,000 metric tons in 1800, but then a series of disasters such as hurricanes, fire ants and leaf rust followed, so that the planting decreased. Finally, in 1942, the last batch of sharp bourbon was shipped back to France, leaving only a pitiful 200 kilograms, and since then, sharp bourbon disappeared without a trace. Even the official documents are no longer mentioned. After the 1950s, coffee was no longer grown on Reunion, and agriculture on the island turned completely to other crops such as sugar cane. Coffee was no longer associated with Reunion, while pointed bourbon was recognized by the coffee industry as "extinct."

In view of this bean, it disappeared for half a century and did not reappear until eight years ago, resulting in the Bourbon pointed body of the country of origin La Reunion Island in the international market. After the price reached more than 500yuan per 100g, Colombia also began to grow this bean, and only Camilo Merizalde, which is the source of many WBC champion beans, dared to take over the transplant of this bean, so this coffee bean, which produces only a few tons of coffee every year, is expensive.

Bourbon variety SL28, SL34

Kenyan "SL28" and "SL34": the bourbon line, screened and cultivated by French and British missionaries and researchers in Kenya in the early 20th century, has adapted to Kenya's high-concentration phosphate soil for a century, giving birth to Kenyan characteristics of sour elves. Top Kenyan coffee comes from these two varieties, but it loses its flavor when transplanted elsewhere.

The coffee grade of Niya is divided into seven grades according to the size of coffee beans and six grades according to the taste. The best coffee in Kenya is bean berry coffee (PB), followed by AA++, AA+, AA, AB and so on. The fine coffee is shiny, delicious and slightly alcoholic. "Kenya AA" is particularly well received in terms of taste.

Graded according to the size of beans:

The best coffee grade in Kenya is bean berry coffee (PB), followed by AA, AB and so on.

PB (PeaBerry) round beans: this is the grading for small round beans. This means that there is only one stone in the coffee fruit, not the common two kernels.

AA: this is a more common grade. Coffee beans are larger in size and have a particle size higher than 18 mesh or 7.22mm. This kind of beans usually get the highest price.

AB: this grade coffee bean combines A (particle size 16 mesh or 6.80mm) with B (particle size 15 mesh or 6.20mm); accounts for about 30 per cent of Kenya's annual coffee production.

Bourbon variety Kaddura

Caturra: it is a single gene variant of bourbon found in Brazil in the 1950s. It has better yield and disease resistance than bourbon. The tree is shorter and easy to harvest. Unfortunately, it has the same problem as bourbon-- as a result, it has a year off, and the flavor is equal to or slightly worse than bourbon beans.

But it is more adaptable, can be planted with high density, does not need shade trees, and can be vibrant in direct exposure to the sun, so it is also called "exposed coffee" (Sun Coffee).

Kaddura is suitable for high altitude areas from 700m to 1700 m, but the higher the altitude is, the better the flavor is, and the bean yield is relatively reduced. There are also variants of yellow Kaddura in Central and South America, but the wind rating is not as good as Huang bourbon.

Bourbon variety Kaduai

Catuai: Kaduai is a hybrid of New World and Kaddura. It inherits the advantage of Kaddura's low stature and makes up for the weakness of Arabica fruit. The result is solid, and it is not easy to fall when the strong wind blows. The biggest regret is that its overall flavor is slightly more monotonous than Kadura.

Kaduai also has the difference between red fruit and yellow fruit, and red fruit wins more often than yellow fruit. Kaduai, Kaddura, New World and bourbon are the four main varieties of coffee in Brazil.

Bourbon variety Pacas

Pacas: a bourbon variety found in El Salvador. In 1935, the Salvadoran coffee farmer "Don Alberto Pacas" selected a high-capacity San Ramon bourbon variety to be planted on a farm. In 1956, his coffee tree produced more fruit than the same kind of coffee tree. Professor "Dr. William Cogwill" of the University of Florida identified this as a genetic mutation in bourbon and named it "Pacas".

Pacas, with its high output and good quality, is popular in Central America. Currently, 68% of El Salvador is bourbon, while Pacas has 29%. Similar to Kaddura of Brazil (Cuturrra) and Villa Sacrhi of Costa Rica. Pacas now accounts for about 25 per cent of El Salvador's coffee production, which is high and has always been popular. It produces coffee with high sweetness, similar to bourbon, but brighter sour taste than bourbon.

Bourbon variety Vera Saatchi

The bourbon variety, which was first discovered in Costa Rica in the Villa Sarchi:1960 era, has often appeared in the cup test list of excellence in recent years, which can be described as a promising dark horse. This is a rare variety bred through the cross of red bourbon tree species. Strong wind resistance, preference for high altitude environment, excellent acidity and a variety of fruit aromas, high sweetness, bright and delicate citrus acidity and low raisin and nut aromas, high complexity and full balance.

It is also a dwarf bourbon, found in the village of Saatchi in the western valley of Costa Rica, suitable for high-altitude organic cultivation, lively fruit acid and obvious caramel flavor.
