Bourbon

Bourbon is one of the two great pillars of cultivated arabica, alongside typica. It is named after the island of Bourbon (now Réunion), where coffee carried from Yemen mutated into a distinct, slightly different plant. From there it spread across Latin America and East Africa and became a cornerstone of modern coffee.

In the cup, classic Bourbon is prized for sweetness, balance, and a pleasant rounded acidity, often with notes of caramel and red fruit when grown at altitude. It yields a bit more than Typica but is still a relatively low-producing, disease-prone plant by modern standards.

Why it matters: Bourbon is a parent or ancestor of a huge share of today’s varieties. Caturra is a compact natural mutation of Bourbon; Catuai descends from it through Mundo Novo; and yellow and pink Bourbon selections add fruit-forward character. If you see a coffee bag listing Red Bourbon, that heritage is the headline. See varietals-deep-dive.
