How Do Red and Yellow Bourbon Differ as Arabica Varieties?

Red Bourbon and Yellow Bourbon are both variants of the Arabica species, and the main difference shows up in the fruit and in the cup. Bourbon cherries normally ripen from green to yellow and then red, but Yellow Bourbon stays at the yellow stage, which is why it stands out when grown at high altitude and processed with the natural method.

Bourbon plants are almost all round beans, slightly smaller than Typica and later to ripen, yet about 30% more productive. They perform better above 1,200 meters than below 1,000 meters and need a year of rest after fruiting. Knowing what is arabica beans helps explain why these two Bourbon types share a lineage but pour differently.

Bourbon is one of the most representative varieties in the Arabica family, and Red Bourbon and Yellow Bourbon are variants that evolved further from it. The two have their own characteristics in appearance, growth traits, and cup performance, especially showing different flavor directions under pour-over extraction. From the perspective of Front Street Coffee's offerings, this article sorts out the quality advantages of Yellow Bourbon, the botanical characteristics of the Bourbon line, and the taste differences between Red Bourbon and Yellow Bourbon under pour-over methods, while briefly reviewing the relationship between the pointed-bean mutation on Bourbon Island and the Arabica lineage, helping coffee enthusiasts more clearly understand the styles and brewing key points of these two beans.

Among the many coffee varieties grown in Brazil, Yellow Bourbon is a rather outstanding variant. Normally, Bourbon fruit gradually turns from green to yellow, then to red, but Yellow Bourbon's appearance and luster remain at the yellow stage throughout. When it is planted at high altitude and processed using the natural method, the cup flavor appears especially excellent.

Bourbon types are almost all round beans, with a bean size slightly smaller than Typica, and a later ripening period, yet their productivity is about 30% higher than Typica. It is suitable for planting in areas above 1,200 meters above sea level, and the flavor performance will be noticeably better than batches below 1,000 meters. Bourbon also has a shortcoming: after bearing fruit, it needs a year of rest. Round-bean Bourbon grows vigorously and has better resistance to leaf rust than Typica, but its flavor is not inferior—one could even say it is superior.

In 1810, some of the round beans on Bourbon Island mutated, forming pointed beans, which became the later well-known "Pointed Bourbon." Its special feature is that its caffeine content is only half that of ordinary varieties, and its yield is low, while the plant itself is weak, making it an extremely rare existence, like a frail yet noble aristocratic youth...

Arabica is now the main cultivated species of specialty coffee, and the several tree species mentioned above all belong to the Arabica system. Among them is the oldest Typica, as well as the Bourbon derived from it; Red Bourbon, Yellow Bourbon, and Green Bourbon are further mutated types of Bourbon. Caturra, Geisha, S28, S32, Pacamara, and others were later obtained by crossing Typica and early Bourbon variants or Robusta, with the aim of improving yield, flavor, and disease resistance. After all, Arabica is far more difficult to cultivate than Robusta.
