Mokka

History

Mokka (also spelled Moka) is one of Arabica's oldest varieties, named after the port of Mocha in Yemen. Its exact genetic origin is still debated, but it is generally thought to come from Yemen's ancient coffee populations. Because its beans are tiny and yields very low, it is difficult to harvest and process, and it nearly disappeared from commercial production. In recent decades, estates on Maui, Hawaii, revived Mokka on a commercial scale, returning it to the specialty market as a "Hawaiian legend"; Brazilian research institutes have also conserved and studied the variety.

Physical Traits

• Tiny beans: noticeably smaller than typical Arabica and nearly round — often mistaken for peaberries
• Dwarf stature: compact trees with short internodes
• Small cherries: picking takes more labor, raising production costs

Flavor Profile

• Concentration: high density of flavor compounds with a firm body
• Classic profile: dark chocolate and cocoa powder; natural lots often show red-wine fermentation notes
• Low acidity: mellow acidity with pronounced caramelized sweetness
• Spice: some lots show cinnamon and dried fruit, reminiscent of Yemeni coffee

Growing Information

• Altitude: 400–1,000 m (shows excellent sweetness even at Hawaii's lower elevations)
• Disease resistance: medium (high drought tolerance)
• Yield: low
• Key trait: extremely tiny beans that require grind adjustment

Roasting and Brewing Tips

Mokka's small, dense beans heat quickly and can scorch on the outside while staying underdeveloped inside, so roasters usually lower the heat and extend the roast. When brewing, the same grinder setting produces finer grounds than usual — start one step coarser and adjust from there. Its chocolate and sweetness peak at medium roast, ideal for pour-over and French press, and it makes a rich single-variety espresso.
