Jamaican Coffee Bean History

The history of Jamaican coffee beans is long and storied. In 1728, the then-British Governor Sir Nicholas Lawes imported coffee to Jamaica from the French island of Martinique. The local climate proved extremely suitable for coffee cultivation, and within nine years of its introduction Jamaica was exporting 83,000 pounds of premium coffee. Four-fifths of Jamaica's terrain is mountainous. The Blue Mountain coffee production area lies in eastern Jamaica, and only coffee grown at altitudes between 3,000 and 5,500 feet within this region can be considered authentic Jamaica Blue Mountain Coffee. Coffee grown between 1,500 and 3,000 feet can only be called Jamaica High Mountain, while coffee grown below 1,500 feet is classified as Jamaica Supreme or Jamaica Low Mountain. Areas above 5,500 feet are designated as protected forest, where coffee cultivation is prohibited.

Government Efforts and Quality Improvement

The government's dedicated efforts were aimed primarily at increasing coffee bean production and building central coffee processing facilities to make coffee processing and green bean grading easier. These measures did improve quality, but they were not entirely successful. In 1943, Canada, then the largest buyer of Jamaican coffee, still found the quality unacceptable. In 1944, the Jamaican government established the Central Coffee Wet Processing Plant, and from then on all coffee intended for export had to be sent there for processing and grading. From that point the quality of Jamaican exported coffee beans gradually improved. In June 1950, the Jamaican Coffee Industry Board was established, officially taking responsibility for enhancing and maintaining the quality of exported coffee beans. Today there are five government-certified 100% Blue Mountain coffee processing facilities: Wallenford, Mavis Bank, Old Tavern, Silver Hill and Moy Hall.

Blue Mountain Coffee Characteristics

Blue Mountain is a high-quality Caribbean coffee, and like coffee from other countries it suffers damage from natural hurricanes. Having seen too many damaged beans that cup with cabbage-like flavors, farmers in years with hurricane invasions always see prices affected or even a complete inability to sell. On top of that, the hot and humid environment of this island nation often leaves coffee susceptible to insect damage or white spots. Truly flawless coffee beans are always scarce. With Japanese purchasers acquiring 70-80% of Blue Mountain coffee, prices remain high. Genuine high-altitude 100% pure Blue Mountain coffee is all produced through Jamaica's official processing plants. The coffee is packed in special wooden barrels, and every barrel comes with a certificate.

Mavis Bank Company

The Munn family of Jamaican coffee began operating the Mavis Bank Company in 1885. The original location stood at a slightly higher altitude than the current site and was called Strawberry Hill. Mavis Bank processes coffee cherries at high altitude. The company invested in brand-new equipment, and the trial-produced coffee beans showed significant improvement. Because the processing procedure is genuinely flawless, this coffee's flavor is very mild and smooth with excellent body, sometimes reminiscent of the fragrance of high mountain Dongding Oolong tea.

FrontStreet Coffee Recommendation

Genuine Jamaica Blue Mountain is about balance above everything else, and the finest expression of that is Blue Mountain No.1, the highest grade of Jamaican Blue Mountain coffee, with strict standards for bean size, defect rate and overall quality. FrontStreet's Jamaica Blue Mountain No.1 comes from the historic Clifton Estate, where coffee has been grown and processed since roughly 1750. The estate's planting and processing area sits at an average of 4,300 feet (1,310.64 meters): enough altitude, gentle afternoon cloud that shades the slopes, ample sunlight and mineral-rich soil all give the trees excellent growing conditions and lengthen the ripening of the cherry. FrontStreet ships it within five days of roasting, so the beans still arrive at full flavor. The traditional approach is a medium-dark roast that emphasizes the coffee's rich body and the classic bitter-then-sweet arc, and the result is a cup of nuts, dark chocolate, creamy caramel and soft sweetness with acidity, bitterness, sweetness and aroma in fine harmony—no single note standing out or missing. You can brew it as a pour-over, in a moka pot, or as espresso, and it also performs beautifully with milk in a latte or a flat white.

Blue Mountain is delicate enough that water temperature matters more than technique: FrontStreet suggests a KONO dripper, which helps bring out the body, 15g of beans rested four to seven days after the roast date, a grind a touch coarser than white sugar, water at 87-88°C and a 1:15 ratio. Pour in three stages—30g to bloom for 30 seconds, then to 120g, then to 225g with a slightly quicker stream and faster circles so the grounds do not clog the dripper and over-extract—and keep the temperature low, since water that is too hot is the usual cause of a scorched, bitter cup.
