What Sets the Bourbon Types of Coffee Seeds Apart?
Bourbon arose as a mutation of Typica and ranks among the oldest coffee varieties still grown. It started from Yemen Mocha, was transplanted by the French to Bourbon Island, now Réunion, and spread from there to Brazil, Central and South America and parts of Africa. The bean is round, cup quality high, with red-wine acidity and a sweet, lingering finish.
Red Bourbon, Yellow Bourbon and French Mission Bourbon differ mainly in fruit color and growing history. The British brought Yemen Mocha to St. Helena Island in 1732, planting the same round-bodied Bourbon there. Yield stays low because the harvest cycle runs about two years, yet the beans are large and uniform, which is why these types of coffee seeds keep winning cupping tables.
Bourbon is an ancient coffee variety that arose from a mutation of Typica, and together with Typica it ranks among the oldest coffee varieties still in existence. It originated from Yemen Mocha, was later transplanted by the French to Bourbon Island (now Réunion) — hence its name — and from there spread to Brazil, Central and South America, and various parts of Africa. Bourbon coffee is known for its round bean shape, excellent cup quality, red-wine-like acidity, and sweet, lingering finish, and is a frequent winner in cupping competitions for specialty coffee in the Americas. This article systematically sorts through the origins, spread, and flavor differences of the three main types — Red Bourbon, Yellow Bourbon, and French Mission Bourbon — and, combined with three representative beans from Front Street Coffee — Brazil Cerrado Red Bourbon, Brazil Queen Estate Yellow Bourbon, and Kenya Chania Estate French Mission Bourbon — introduces their respective roasting recommendations, brewing parameters, and flavor profiles, helping coffee lovers fully understand the appeal of the Bourbon family.
【Coffee Variety Preface】
After Typica was transplanted to Yemen in the early period (prehistoric times of coffee), it underwent a mutation, and its bean shape changed from slender and pointed to round. In 1715, the French brought the round beans of Yemen Mocha to Bourbon Island off the east coast of Africa (renamed Réunion after the French Revolution), and the name Bourbon derives from this. Thereafter, round-bodied Bourbon beans reached Brazil and Central and South America in 1727, and in 1732 the British transplanted Yemen Mocha to St. Helena Island (the place where Napoleon was later imprisoned), where what was planted was likewise round-bodied Bourbon. Bourbon has repeatedly taken top honors in cupping competitions for specialty coffee in the Americas.
Bourbon is a secondary species produced by a mutation of Typica, and together with Typica it belongs to the oldest coffee varieties still in existence; its fruit is bright red when ripe. Compared with Typica, Bourbon has broader leaves and denser growth, and although its yield is higher than Typica's, its harvest cycle is likewise two years, so it is still a low-yield variety; yet it possesses excellent cup quality — acidity similar to red wine, with a sweet finish. Its coffee beans are relatively large, uniform in size, even in color, and glossy. To make picking easier, farmers usually prune the trees to no more than 150 cm in height.
【Coffee Variety: Red Bourbon】
The fruit color of Red Bourbon changes in sequence as it ripens: green > slightly yellow > slightly orange > ripe red > riper dark red, which is why it is also called Red Bourbon. In fact, Red Bourbon is simply what is commonly called Bourbon. Red Bourbon grown at high altitudes often has better aroma and brighter acidity, and can even carry a red-wine-like flavor on the palate.
【Coffee Variety: Yellow Bourbon】
Yellow Bourbon comes from a cross between Bourbon and other varieties, and because of its low yield and poor resistance to wind and rain, it has not been planted on a large scale. However, when cultivated at high altitudes, it can display an excellent flavor, and in recent years it has gradually become more common. Yellow Bourbon, that is, huang bourbon, has yellow fruit when ripe; it was first discovered in Brazil and is currently mainly grown there. It is generally believed that it may have originated from a mutation after a cross between a red-fruited Bourbon and a yellow-fruited Typica variant called "Amerelo de Botocatu."
【Coffee Variety: French Mission Bourbon】
In Africa, French missionaries known as Spiritan (from the Congregation of the Holy Spirit) played a key role in the spread of Bourbon. In 1841 the first mission was established on Réunion, and in 1859 a branch was set up in Zanzibar; starting from Zanzibar, in 1862 branches were established at Bagamoyo (on the coast of Tanzania, then called Tanganyika) and St. Augustine (Kikuyu, Kenya), and in 1893 another branch was founded at Bura (Taita Hills, Kenya). Each time a branch was established, coffee seeds brought out from Réunion were planted locally along with it.
In 1899, seedlings cultivated at Bura were sent to another French mission at St. Cruz (near Nairobi), and in 1900 they were introduced to the Kilimanjaro region of Tanzania, with seeds distributed to local residents willing to grow coffee — this is the origin of "Mission Bourbon." Subsequently, the Kent variety was also introduced in 1920. Therefore, even today, Tanzanian coffee is still dominated by Bourbon and Kent.
The following all belong to the Bourbon variety:
【Front Street Coffee Brazil Cerrado Red Bourbon】
On some estates in the Cerrado region of Minas Gerais state in southeastern Brazil, the ancient Bourbon coffee is grown. The Cerrado plateau of western Minas and southern Minas mostly lie above 1,100 meters in elevation, with diverse landforms, distinct wet and dry seasons, large day-night temperature differences, and rich microclimates, making them suitable for cultivating the elegant-flavored Red Bourbon and Yellow Bourbon, and naturally making them the main producing areas of Brazil's specialty coffee.

【Front Street Coffee Brazil Queen Estate Yellow Bourbon】
From Fazenda Rainha (Queen Estate), the estate covers 280 mu and is located in Brazil's ancient volcanic valley, Vale da Grama. Queen Estate belongs to the prestigious and respected Carvalho Dias family. The family's four major estates have won awards every year since the first Brazil COE competition in 1999, winning more than 12 times in 7 years; in 2004 it even swept the champion, 9th place, and 11th place, standing out among Brazil's estates large and small.

【Front Street Coffee Kenya Chania Estate French Mission Bourbon】
In Kenya, what is often mentioned is the K72 processing method and the two varieties SL28 and SL34, so a naturally processed French Mission Bourbon is truly rare. Chania Estate has unique red volcanic soil, combined with suitable coffee-growing temperatures and rainfall, plus a superior natural environment, creating the distinctive flavor of Chania Estate's French Mission Bourbon.
Roast level: Medium roast
Recommended brewing method: Pour-over
Grind size: 3.5 (Fuji Royal R440)
Water temperature: 90℃
Dripper: V60

Flavor: On the palate one can perceive caramel, vanilla, and mixed fruits, with a solid juicy quality; the finish has berries, rich jackfruit, and coffee floral notes, presenting on the whole the wild regional flavor of Africa.
Overall, the beans of the Bourbon coffee varieties 【Front Street Brazil Cerrado Red Bourbon】【Front Street Brazil Queen Estate Yellow Bourbon】【Front Street Kenya Chania Estate French Mission Bourbon】 are relatively similar in flavor, all carrying obvious notes of dark chocolate, cocoa, nuts, and caramel, with gentle acidity and low bitterness.
When Bourbon is planted in different regions, its flavor direction varies under the influence of terroir factors such as microclimate, soil composition, and growing environment. Kenya's volcanic ash soil has a relatively high phosphoric acid content, giving 【Front Street Kenya Chania Estate French Mission Bourbon】 the acidity of tropical fruit while also continuing the Bourbon flavor, making this Front Street Kenya bean even more complex in flavor. That's all for today's sharing — I hope it has been helpful to everyone~
