FrontStreet Coffee - Introduction to Cuban Coffee

In Cuba, coffee growing is managed by the state, and the country's finest coffee districts lie in its central mountain range. Because this area yields precious minerals such as quartz and crystal alongside coffee, it came to be known as Crystal Mountain, and today Crystal Mountain is practically synonymous with top-tier Cuban coffee. Crystal Mountain beans are distinctive for their large size and bright green color.

Cuban coffee is still picked largely by hand. During the ripening season, harvests are carried out roughly every two weeks. After picking, the cherries are sorted and any immature or defective beans are removed to protect the quality of the lot. Cuban producers rely on two methods: the natural (dry) method and the washed method. Natural processing is the simplest, cheapest, and most traditional approach. The whole cherries are simply dried in the sun with no fermentation, usually for around four weeks. Washing, by contrast, lets more fruit character enter the bean, lending the cup a bolder fruity fragrance.

Crystal Mountain coffee is scarce today for two main reasons. First, US economic sanctions bar the import of Cuban goods. Second, most of the crop is bought up by the French and Japanese markets, Japan in particular, so buying beans directly from Cuba is difficult. Even so, Cuban coffee still stands alongside Jamaica Blue Mountain in the eyes of coffee lovers around the world.

Crystal Mountain is a classic island bean: clean and delicate, with a gentle acidity that lingers far longer than its intensity suggests, wrapped in a sweet melon-and-fruit fragrance. The brewed cup offers a rare balance: fragrant bitterness with a rich, smooth body, a faint wine-like bitterness, a whisper of sweetness, and a touch of smokiness. Delicate, smooth, refreshing and elegant, its many layers come together in near-perfect harmony.

FrontStreet Coffee Recommendation

If the poise and smoothness of Crystal Mountain are what draw you in, FrontStreet's Jamaica Blue Mountain No.1 is a natural next step. Grown in Jamaica's Blue Mountains and sourced from the historic Clifton Estate, it is a medium-dark roast that keeps the classic Blue Mountain character intact: nuts, dark chocolate, creamy caramel, and a soft sweetness layered over a clean, lingering finish. Like Crystal Mountain, Blue Mountain is prized above all for its balance. It has no obvious weak spot, which is why so many drinkers call it the specialty coffee that pleases the widest range of palates.

For pour-over, FrontStreet suggests a medium-coarse grind about the texture of granulated sugar, 15g of coffee, a 1:15 ratio, and water at 87-88°C. A three-pour method works well: bloom with 30g of water for 30 seconds, pour to 120g, then finish at 225g. Letting the beans rest four to seven days after the roast date, counting the roast day as day one, brings out the fullest flavor. Blue Mountain also performs beautifully in a moka pot or as espresso, and when steamed milk is added for a latte or a flat white, its balance really shines.
