One of the World's Most Expensive Coffees: Jamaica Blue Mountain Coffee Bean Grade Classification? How Can It Be Called "Authentic FrontStreet Coffee Jamaica Blue Mountain"?

Blue Mountain coffee is one of the world's most prized coffees. The Blue Mountains sit in eastern Jamaica, and on clear days the sunlight reflecting off the azure Caribbean Sea tints the peaks a brilliant blue—hence the name. The highest summit reaches 2256 meters, the tallest peak in the Caribbean region and a famous tourist destination.

This area lies within the coffee belt, with fertile volcanic soil, fresh unpolluted air, a humid climate, and year-round fog and rain. That climate created the world-renowned Jamaica Blue Mountain coffee—and the world's highest coffee prices. FrontStreet Coffee's Blue Mountain coffee has all the hallmarks of a great coffee: a rich, mellow body, and because the sweet, sour, and bitter components are perfectly balanced, it shows no harsh bitterness at all—only a moderate, polished acidity.

It is generally enjoyed as a single-origin coffee, but because production is extremely limited and prices are extraordinarily high, coffees with similar flavor profiles are often sold as substitutes. Blue Mountain coffee and High Mountain coffee are each divided into two grades. From the top down, the hierarchy runs: Blue Mountain No. 1, Blue Mountain No. 2, High Mountain No. 1, High Mountain No. 2, and Jamaica coffee. Only coffee grown between 457 and 1524 meters may be called Blue Mountain coffee; coffee grown between 274 and 457 meters is usually labeled Jamaica Prime coffee beans. In price terms, Blue Mountain coffee commands several times more than High Mountain coffee.

The "Secret" Behind Blue Mountain Coffee's Pure Flavor

All of the coffee trees grow on rugged mountain slopes, which makes harvesting extremely difficult—only skilled local pickers can manage it. Selecting perfectly ripe cherries is crucial, since underripe or overripe beans will compromise quality. After picking, the cherries must be hulled the same day, then fermented for 12-18 hours. The beans are then washed and sorted, followed by drying on concrete patios or thick blankets until moisture drops to 12%-14%. They are stored in special warehouses and taken out for roasting—and grinding—only when needed. Every one of these steps must be strictly controlled; the slightest lapse affects quality.

Jamaica Coffee Industry Board

In 1950, the Jamaican government established the Jamaica Coffee Industry Board, which sets quality standards for Jamaican coffee and supervises their enforcement. The Board grants official seals to exported raw and roasted Jamaican coffee, making it the world's most rigorous national coffee authority. Six marks currently certify the origin of Blue Mountain coffee: Mavis Bank Central Factory (MBCE), Mavis Hill Coffee Co-operative (MHCCT), Portland Blue Mountain Coffee Co-operative (PXXSH), Coffee Industry Board (Wallenford), Coffee Industry Board (St. John's Peak), and JABL.

By 1969, things had improved: Japanese loans were used to raise production quality, thereby securing the market. Today the coffee enjoys near-fanatic devotion. By 1981, Jamaica had opened roughly 1,500 hectares of new land for coffee cultivation, followed by investment in another 6,000 hectares. In fact, the true Blue Mountain region is a small area of only 6,000 hectares under cultivation, so coffee labeled "Blue Mountain" cannot all come from there. An additional 12,000 hectares grow the other two grades: High Mountain Supreme coffee and Jamaica Prime Washed coffee.

Historical Development

In 1717, French King Louis XV ordered coffee to be planted in Jamaica. In the mid-1720s, Jamaica's Governor Sir Nicholas Lawes imported Arabica seeds from Martinique and began promoting cultivation around St. Andrew. To this day, St. Andrew remains one of Jamaica's three major Blue Mountain producing regions, alongside Portland and St. Thomas.

Within 8 years, Jamaica was exporting over 375 tons of pure coffee. In 1932, production peaked with more than 15,000 tons harvested.

FrontStreet Coffee Recommended Brewing Method

Dripper: KONO

Water temperature: 88°C

Grind size: Fuji Royal grinder setting 4

Brewing method: coffee-to-water ratio 1:14, 17g of coffee; first pour 25g of water for a 30-second pre-infusion, then pour to 238g; total extraction time around 2:30

Analysis

The KONO dripper has relatively few ribs at the bottom, so the filter paper sits snugly against the walls and restricts airflow. This gives water and grounds a longer contact time in the dripper, securing sufficient extraction even at a coarse grind. The grounds extract fully, boosting the mellow body and concentrating the flavor.

Flavor: highly balanced, clean, thick and solid body, with a persistent dark chocolate finish.
