FrontStreet Coffee: The Three Major Coffee Varieties and Jamaica Blue Mountain

Biologically speaking, coffee divides into Arabica, Robusta and Liberica. The varieties actually consumed worldwide are Arabica and Robusta; Liberica is largely overlooked because of its limited production and inconsistent quality.

Arabica is generally used for single-origin or specialty coffee, while Robusta is typically used to make instant coffee. That said, treating Arabica as premium and Robusta as second-rate is too rigid a rule — it makes more sense to separate them by personal taste. From the standpoint of preference, the United States and Japan more commonly drink light coffee brewed from Arabica, while Europe favors espresso blended from Arabica and Robusta.

Typica, a derivative of Arabica, is the variety behind Jamaica Blue Mountain coffee.

Jamaica Blue Mountain Coffee

Jamaica Blue Mountain is one of the world's famous island coffees, and the variety grown in Jamaica's Blue Mountains is Typica. Typica is highly susceptible to leaf rust disease, and the widely planted Typica of Central and South America was progressively replaced as rust outbreaks spread. Jamaica, with its particular geography, still grows mainly Typica, and the incidence of leaf rust there remains very low.

Because Jamaica is an island nation in the Caribbean Sea, Blue Mountain coffee enjoys no advantage in growing altitude, so it lacks the pleasant bright acidity found in high-altitude Central American coffees. Mild and low in acidity is its signature, even though Blue Mountain soil is also of volcanic origin. Since the growing altitude is not especially high, the body is medium — it is fairer to describe Jamaica Blue Mountain as having a gentle, mellow aroma than as full-bodied.

Blue Mountain SOE Espresso Preparation

Did you ever think Blue Mountain could be pulled as espresso? How is a Blue Mountain SOE made? Proper puck preparation means leveling the surface of the grounds, then tamping at about 25 kg/m² (we use a calibrated tamper, so the pressure stays consistent). The grind setting is #1.9, an extra-fine level close to the texture of salt. A single shot extracts 20 g of liquid from 13.5 g of grounds in 27 seconds; a double shot extracts 40 g of liquid from 20.5 g of grounds in 26 seconds (the maximum dose is 14 g for a single and 22 g for a double). Because the beans are relatively fresh, the crema is moderate, golden in color with a rich caramel aroma. On the palate you first meet a gentle fruity acidity that opens into caramel sweetness, with chocolate and brown sugar in the finish.

Blue Mountain Americano

Mixed with hot water to make an Americano, Blue Mountain espresso gains noticeably more sweetness and becomes lighter, the fruit acidity drops away, and a rich dark-chocolate note lingers in the mouth.

FrontStreet Coffee Recommendation

Blue Mountain's reputation rests on exactly the quality described above — balance — and the variety behind it is Typica, the same ancient Arabica cultivar. If that kind of cup appeals to you, FrontStreet Coffee's Jamaica Blue Mountain No. 1 is the highest grade in the series, sourced from the long-established Clifton Estate, where coffee has been grown and processed since around 1750 at an average elevation of 4,300 ft (1,310.64 m). The altitude, the gentle afternoon cloud that shades the hillsides, abundant sunlight and mineral-rich soil all slow the ripening of the cherries and give the coffee its depth.

Authenticity is worth checking when you buy Blue Mountain, because the name is strictly protected: the Jamaican authorities certify it, and importers hold the full export documentation and proof of origin. Traditional Blue Mountain is shipped in the characteristic wooden barrels of 15, 45 and 70 kg, each stamped with the green-bean lot details, and the barrels themselves are one of the marks of the genuine article. FrontStreet Coffee roasts its Blue Mountain within five days and ships it while the flavor is still at its fullest, using a medium-dark roast to bring out the classic body and the sweet-after-bitterness balance. In the cup you get the nut, dark chocolate, cream caramel and soft sweetness that have kept this coffee famous for decades.

For pour-over, FrontStreet Coffee suggests a 1:15 to 1:16 ratio, a medium-coarse grind and water at 85–88°C; a Kono dripper suits it particularly well because it builds the thick mouthfeel, and the beans are best rested 4–7 days from the roast date. Grind a little coarser than you would for a light roast — about the size of white sugar — and pour in three stages: a 30 g bloom for 30 seconds, a second pour to 120 g with a slow vertical spiral, and a third to 225 g with a slightly faster stream. If you want even more intensity, the same beans also make an excellent moka pot or milk drink.
