Mocha takes its name from the Yemeni port that was the primary export point for Arabian coffee from the 15th–17th centuries. Before Brazilian and Colombian coffee dominated global trade, Mocha (Yemen) was synonymous with fine coffee. The port's name gave both the coffee variety and the colour their names.

Warm, grounding, and contemporary. Mocha occupies a middle ground between the darkness of espresso and the warmth of caramel — it is the most approachable of the coffee browns. Associated with contemporary café culture, the warmth of shared conversation, and the particular comfort of a warm drink in a cool space.

Starbucks' global expansion from the 1990s onward brought "mocha" into everyday language as a coffee drink (espresso with chocolate) and a colour simultaneously. The "mocha aesthetic" — warm browns, exposed wood, comfortable seating — became a global template for café design. Yemen's Mocha port, once the centre of global coffee trade, is now largely unknown to the coffee drinkers whose language it gave.
