Last Updated: 2026/01/28, Explore professional coffee expertise and bean insights by following Coffee Workshop (WeChat: cafe_style). Jamaica Blue Mountain stands as an exceptional regional treasure, cultivated exclusively in the Blue Mountains of Jamaica. Much like Hangzhou's prestigious Longjing tea, authenticity is defined by terroir—only leaves harvested from the mountain slopes of Longjing Village beside West Lake bear the true mark of genuine quality.

It could be said that everyone who has encountered coffee has heard of the famous Blue Mountain. If FrontStreet Coffee were to summarize this coffee bean in one sentence, it would be: a high-quality Typica coffee from Jamaica's Blue Mountains, processed using the washed method and roasted to a medium-dark level.

Typica Variety

Typica, with its mellow aroma, is a high-quality coffee variety still cultivated in various parts of the world today, with Jamaican Blue Mountain being the most renowned. Growing Typica coffee beans with elegant and pure flavors is no simple task. Every stage—from the natural terroir conditions and plant management to fruit harvesting and post-processing—requires meticulous attention for the coffee beans to develop positive flavors and mouthfeel. This means producing high-quality Typica requires greater investment in labor costs and cultivation techniques, which explains why Blue Mountain and Kona coffees are so precious.

The most distinctive feature of the Typica variety is its reddish-bronze colored leaves at the top, hence it's also called "red-topped coffee." Typica trees have a conical shape with slightly inclined branches, forming 50-70° angles with the vertical stem. Their trunks are slender and branches are thin. Due to their height and long branch characteristics, Typica trees require sufficient spacing when planted. FrontStreet Coffee has a Typica tree planted next to its Dongshankou store, so you might want to take notice.

Typica coffee beans are relatively large, elongated, and pointed at both ends, somewhat resembling eggs. After roasting, they often exhibit citrus acidity with unnoticeable bitterness and a sweet aftertaste. The overall cleanliness is high, praised by many for their elegant and refined flavor characteristics.

However, Typica has very poor disease resistance, struggling against common diseases such as leaf rust and berry disease... Additionally, its yield is quite scarce. Leaf rust is the most severe plant disease, first appearing in the coffee-growing regions around Lake Victoria in East Africa in 1861. In 1970, a leaf rust outbreak occurred in Bahia, Brazil, and since then, leaf rust cases have been discovered one by one in all coffee-producing regions worldwide. Coffee trees infected with leaf rust are equivalent to having an incurable disease, eventually withering and even dying. As an economic crop, Typica—with its low yield and susceptibility to diseases—becomes difficult to cultivate profitably, leading many growers to abandon it in favor of varieties with better disease resistance.

On FrontStreet Coffee's regular bean menu, there are three Typica varieties: Jamaican Blue Mountain No. 1 Coffee Beans, FrontStreet Coffee 2013 Natural Process Typica Coffee Beans, and Papua New Guinea Bird of Paradise Coffee Beans. Grown in different terroir conditions and processed using different methods, Typica can exhibit distinct flavors and mouthfeel.

Jamaican Blue Mountain Region

The high quality of Blue Mountain coffee is inseparable from the advantages of its growing environment. The Blue Mountain Range is surrounded by Caribbean Sea waters, creating a unique island-style tropical rainforest microclimate. During rainy seasons, rainfall is concentrated with good drainage. Volcanic ash from active volcanoes enriches the soil with nutrients, so coffee trees require minimal irrigation and fertilization. With abundant year-round sunshine, surrounded by mist, the cool and comfortable high-altitude growing area is excellent for various crops. Locals typically plant coffee trees alongside banana trees on the slopes of the Blue Mountains.

The CIB (Coffee Industry Board) has designated an area of approximately 6,000 hectares in the Blue Mountain Range, with strict regulations: only Typica coffee produced in this region can be called "Blue Mountain Coffee." According to the areas designated by CIB, the forest regions where Blue Mountain coffee is grown are located at altitudes of 910-1,700 meters. The high altitude combined with ideal climate characteristics allows coffee cherries to fully absorb essences and transform into various aromatic compounds. The higher the altitude, the more prominent the Typica flavors become.

However, Typica has poor disease resistance and is susceptible to infections, coupled with low yield per plant, requiring more careful manual attention. Additionally, the high-altitude areas of the Blue Mountains have uneven terrain, making management and harvesting very difficult. This demands high skill levels from harvesters, further affecting yield. In recent years, less than 15% of coffee beans produced in Jamaica can carry the Blue Mountain Coffee label, approximately 900 tons. After harvesting, coffee cherries are immediately transported to processing plants for processing using the washed method to remove the fruit pulp and dry them.

How Does FrontStreet Coffee Roast Jamaican Blue Mountain?

When FrontStreet Coffee receives Jamaican Blue Mountain No. 1 raw coffee beans, they are uniform and plump, consistently sized, and overall have a translucent blue-green color. FrontStreet Coffee uses medium-dark roasting to maximize the presentation of Blue Mountain's chocolate and nutty aromas while preserving soft acidity and sweetness, creating a balanced overall mouthfeel.

Simply put, FrontStreet Coffee roasts the Blue Mountain beans thoroughly "inside and out." Based on the foundation of proper roasting, good roasting techniques are used to express the flavors of FrontStreet Coffee's Jamaican Blue Mountain beans.

Caramelization is one of the most significant processes affecting coffee flavor. After six to seven minutes of roasting, raw beans absorb a large amount of heat energy, initiating pyrolysis reactions and the first crack sound. Some sugars convert to carbon dioxide, water continues to evaporate, and new aromatic compounds gradually develop, forming so-called coffee oils that combine with hundreds of aromatic substances including nicotinic acid, citric acid, quinic acid, malic acid, acetic acid, caffeine, and more.

Roasting Profile

Set the roaster temperature to 170°C and start roasting with the damper at 3. After 1 minute, adjust the heat to 140°C, keeping the damper unchanged. At 5'10", when the temperature reaches 153°C, the bean surface turns yellow and the grassy aroma completely disappears, indicating dehydration is complete. Adjust the heat to 115°C and change the damper to 4.

At the 8'00" minute, ugly wrinkles and black spots appear on the bean surface, and the toast aroma clearly transitions to coffee aroma, which can be defined as the prelude to first crack. At this time, listen carefully for the sound of first crack. At 8'12", first crack begins, adjust the heat to 90°C with the damper fully open (be very careful when adjusting heat—don't reduce it so much that the cracking stops), and finish roasting at 201.3°C.

Immediately after roasting, FrontStreet Coffee conducted a cupping of the fresh Blue Mountain coffee beans. The dry aroma revealed nuts, sweet melon, and chocolate. After adding hot water, notes of oolong tea, caramel, honey, and dark chocolate emerged. The tasting experience was rich with dark chocolate, roasted hazelnuts, cream, and brown sugar, presenting clean and clear flavors with a mellow mouthfeel and persistent aroma.

FrontStreet Coffee's Barista Brewing Suggestions

FrontStreet Coffee typically uses a KONO dripper for extracting medium-dark roasted coffee beans. The upper part of the KONO dripper features a smooth curved surface that allows better adherence of the filter paper. Compared to the V60 dripper, KONO primarily extracts coffee through immersion, increasing the overall concentration to enhance the coffee's body. Besides KONO, common slow-flow-rate brewers like the Kalita wave trapezoidal dripper and flannel filters are also suitable. Additionally, considering that medium-dark roasted coffee has undergone a certain degree of roasting, the internal structure of the beans becomes more porous than lightly roasted coffee, thus absorbing water better. To avoid over-extraction, FrontStreet Coffee chooses a grind size with 75% passing through a #20 standard sieve, along with 88°C water temperature, combined with FrontStreet Coffee's customary three-stage pouring method.

Pour-over Parameters

Water temperature of 88°C, coarse sugar-like grind size (75% pass rate through #20 standard sieve), 15g of coffee beans, 1:15 coffee-to-water ratio, three-stage extraction.

For the first stage, gently pour 30g of water for blooming, with a bloom time of 30 seconds. For the second stage, pour to approximately 125g of water, circling evenly and steadily outward. Then wait for the coffee liquid to drop, and when it reaches halfway, pour the final stage of water to 225g. Wait for all the coffee to drip through, with a total extraction time of approximately 2 minutes.

Blue Mountain No. 1 Coffee Flavor Profile

At high temperatures, Blue Mountain No. 1 coffee presents a rich dark chocolate aroma with significant body and distinct almond aftertaste. As the temperature decreases, roasted hazelnut and creamy sweetness emerge with silky texture, accompanied by a hint of soft acidity and caramel sweetness, with the aroma persisting in the mouth.
