What Is Maui Mokka Coffee? Rare Hawaiian Variety Explained

If you’ve ever wondered why some coffee varieties grow well in unlikely places or look strikingly different from the beans you usually see, Maui Mokka is a great example. This unusual coffee plant produces tiny, round beans and thrives under conditions that would challenge most other varieties—but what makes it unique, and where does it actually come from?

Maui Mokka is a rare coffee variety primarily grown on Maui Island in Hawaii, with a small amount also cultivated in Brazil at low elevations. It’s known for its small, rounded green beans, short coffee tree stature, and distinctively bold cup despite its low-altitude origins.

What Is the Maui Mokka Coffee Variety?

Maui Mokka refers to a specific coffee plant variety recognized for its compact growth habit, small leaves, and especially its very small, nearly round green coffee beans. Visually, these beans are notably different from more common varieties like Typica or Bourbon. The plant itself is relatively short, adding to its distinct profile both in the field and in the cup.

Origins: Two Theories on Maui Mokka’s Background

There are two main explanations for the origins of the Maui Mokka variety. One theory suggests it is a spontaneous mutation of the old Bourbon variety that originated on the island of Bourbon (now Réunion). The other proposes that it was brought over from Yemen as a transplant of the traditional Mokka (or Mocha) variety. Regardless of its exact lineage, Maui Mokka has established itself as a distinct cultivar, particularly associated with the island of Maui in Hawaii.

Growth Traits and Challenges

Maui Mokka plants are characterized by their small size, reaching lower heights than many other coffee cultivars. Their leaves are described as small and slender. Most notably, the variety produces very small, rounded green coffee beans. However, these traits come with trade-offs: Maui Mokka is highly susceptible to coffee leaf rust (a common fungal disease in coffee-growing regions) and yields are notably low compared to more common commercial varieties. These factors make it a challenging plant to cultivate on a large scale.

Where Maui Mokka Is Grown

Outside of its association with Maui Island in Hawaii, Maui Mokka is also grown in limited quantities in Brazil. Interestingly, even when cultivated at relatively low altitudes—where many other varieties struggle to develop complexity—the Maui Mokka variety still delivers a notably strong and bold flavor profile. This resilience contributes to its reputation as a unique and hardy coffee plant.
