Introduction:Cuban Crystal Mountain coffee is renowned for its smooth texture and distinctive aroma, and Cubita, as the representative brand of the region, crafts premium specialty coffee with Caribbean flair through rigorous green bean selection and traditional washed processing. This article delves into the origin background of Cubita, the Cuban coffee grading system, compares it with Blue Mountain coffee, and provides a complete step-by-step guide to using a siphon brewer — from filling water and lighting the flame to adding coffee grounds — to help you unlock the rich complexity of this high-altitude coffee.

Among the many Cuban coffee brands, Cubita has consistently held a leading position in the market. The coffee beans used by this brand all come from the high-altitude growing regions of Cuba’s Crystal Mountain. These pristine lands nurture coffee trees that grow in a pollution-free environment, resulting in beans with inherently pure flavors. The green beans are rigorously selected according to a 17 to 19 mesh standard, keeping only those that are plump in shape and fully mature. Hand-picking ensures that every bean is in optimal condition.

These carefully selected coffee cherries are then refined using the traditional washed processing method. This technique effectively removes pulp residue and defective beans, preserving the coffee beans’ most original aromas and acidity. With professional roasters controlling the roasting profile, the final cup delivers a uniquely sweet, refreshing flavor with delicate acidity and a smooth mouthfeel. The aroma is so vivid that it wafts directly into your nose during brewing, leaving a lasting impression.

The cultural roots of Cuban coffee trace back to the period of French immigration, when it was highly popular among the upper class. Today, Cuban coffee beans are primarily exported to countries such as Japan, France, Germany, Ireland, Canada, and China, with Japan being a major buyer. The Cubita coffee sent to China is made exclusively from pollution-free green beans sourced from the high-altitude areas of Crystal Mountain. As a typical Caribbean-type coffee bean, it is refined using the traditional washed process, showcasing a rich and bold regional character.

Cuban coffee is subdivided into nine grades based on quality, with Crystal Mountain being the highest. This grade is known for its sweet and refreshing taste, bright aroma, delicate acidity, and smooth mouthfeel, along with good body. As for Cuban Blue Mountain, it carries a strong Caribbean character with large, plump beans and an attractive appearance. Its flavor is similar to Jamaican Blue Mountain but offers a unique balance, with sweet, acidic, and bitter notes harmoniously blended. It has a medium body, gentle acidity, and overall stable performance, making it considered the finest among Cuban coffees.

If you want to fully experience the charm of Cubita coffee at home, the siphon brewer is an excellent choice. Here is the detailed operation process: First, fill the lower chamber with hot water up to the “two-cup” water level mark. Then, place the filter inside the upper chamber and gently pull the end of the chain to hook it securely onto the tip of the glass tube. Be careful not to release the hook abruptly to avoid damaging the glass tube.

The next step is to light the flame and tilt-insert the upper chamber. After igniting the alcohol lamp, slightly tilt the upper chamber and place it into the lower chamber, ensuring the rubber edge tightly seals against the spout and that the chain is completely submerged in the water. Begin heating and wait until continuous large bubbles rise from the lower chamber — ignore the small bubbles for now. Make sure to keep the upper chamber tilted to prevent the lower chamber from sealing completely.

When the lower chamber continues to produce large bubbles, gently straighten the upper chamber, make slight left-right adjustments, and press it down slightly so it settles steadily into the lower chamber. At this point, you’ll observe the water gradually rising into the upper chamber. It’s advisable to wait briefly and let the rising bubbles subside before proceeding to the next step. If you’ve already prepared your grinder, you can now begin grinding the coffee beans. For a two-cup water volume, it’s recommended to use about three scoops (24 grams) of coffee grounds with a medium grind size.

Finally, once the water in the lower chamber has completely risen into the upper chamber, don’t rush to pour in the coffee grounds right away. It’s best to wait a few seconds until the rising bubbles have significantly decreased before adding the coffee grounds. This ensures a smoother coffee extraction process, fully releasing the rich aroma and layered complexity of Cuban Crystal Mountain coffee.
