For more premium coffee knowledge, follow FrontStreet Coffee.

If you ask which coffee is the most beautiful cloud in the sky, everyone probably has a different answer, but one veteran superstar is impossible to overlook — FrontStreet Coffee's Jamaica Blue Mountain. Even in 2020, it remains a formidable competitor that many newer varieties cannot challenge, and it is still expensive today. Yet even when it is expensive, you need to know how to choose. Today FrontStreet Coffee will share with you what genuine Jamaica Blue Mountain coffee really is.

History of Jamaica Blue Mountain Coffee

The history of Jamaican coffee goes back to the 18th century. In 1717, King Louis XV of France ordered coffee planted in Jamaica. In the mid-1720s, Jamaica's Governor Sir Nicholas Lawes imported Arabica seed from Martinique and began promoting cultivation in the St. Andrew area. Coffee trees were introduced to Jamaica and planted in the Blue Mountains, and the crop was divided into high-altitude Jamaica Blue Mountain coffee, High Mountain coffee, and Jamaica coffee, with different grades determining different prices.

Jamaica Certified Authentic Blue Mountain Coffee Region

The Blue Mountains lie in eastern Jamaica, at an altitude of 1000-1700m. Only Blue Mountain coffee grown in this region can be considered authentic Blue Mountain coffee. Because the mountain is surrounded by the Caribbean Sea, on clear days when the sun shines directly on the azure water the peaks reflect the brilliant blue light of the sea, hence the name.

Blue Mountain lies in the coffee cultivation belt, with fertile volcanic soil, fresh air, no pollution, a humid climate, and year-round fog and rain (average precipitation of 1980mm, temperature around 27°C). This climate created the world-renowned Jamaica Blue Mountain coffee. The region certified by the Jamaican government as authentic Blue Mountain coffee covers four eastern administrative districts: St. Andrew, St. Thomas, St. Mary, and Portland. FrontStreet Coffee's washed Blue Mountain and natural-processed Blue Mountain both come from the Clifton Mountain Estate within Jamaica's certified Blue Mountain coffee region. Clifton Mountain Estate is also the only farm in the Blue Mountain growing area with Rainforest Alliance certification. Rainforest Alliance certification means traditional cultivation under native forest shade, which helps protect the ecosystem; part of the alliance's revenue is also used for wildlife protection in tropical rainforest reserves and for improving workers' living conditions.

Why Did Japan Have Priority Purchasing Rights for Jamaica Blue Mountain Coffee in the Past?

In 1950, the Jamaican government established the Jamaica Coffee Industry Board, which set quality standards for Jamaican coffee and supervised their implementation to ensure quality. The board issues special official seals for Jamaica's exported green coffee and roasted coffee. Because Japanese loans were used to improve production quality, the Blue Mountain coffee market was secured. In 2009, Jamaica ended Japan's priority purchasing rights. In April 2011, the first batch of Jamaica Blue Mountain No. 1 coffee arrived in mainland China.

Jamaica Coffee Industry Board CIB

Jamaica is the only country in the world with a government coffee management organization — the Jamaica Coffee Industry Board (CIB), under the Jamaica Ministry of Agriculture and Fisheries. CIB's functions include guidance on cultivation technology, processing training, fair trade, and quality supervision, along with other matters concerning the quality and brand of Jamaica Blue Mountain. CIB board members are all estate owners who hold a certain scale of coffee plantation in Jamaica (because of industry shifts, newly certified Jamaica Blue Mountain estates must now cover 50 hectares or more).

CIB stipulates that only Blue Mountain coffee produced above 2200 feet in the Jamaica Blue Mountain region may be called Jamaica Blue Mountain. Its grades are divided by bean size into NO.1, NO.2, NO.3, and manually selected PB. For FrontStreet Coffee's Blue Mountain No. 1 green beans, the basic standards are beans above 17 screen, a defect rate below 3%, and a moisture content around 13%. Today, all exported Blue Mountain coffee on the market requires a certificate issued by CIB.

How to Identify True FrontStreet Coffee's Jamaica Blue Mountain Coffee

1. Designated export company by the National Coffee Board. 2. The only region that packs its green beans in wooden barrels. FrontStreet Coffee wants to remind you of two misconceptions when buying Jamaica Blue Mountain:

One is that many businesses roast beans from other regions, or a mix of varieties, slightly darker to strip away their flavor characteristics and approximate Blue Mountain's flavor. These businesses play word games, labeling non-Blue Mountain beans as "Blue Mountain style coffee." Because Jamaica Blue Mountain is so popular, many counterfeit coffees have appeared on the market — Blue Mountain style coffee, Blue Mountain blend coffee, or simply "Blue Mountain coffee." These are blends created by industry professionals who simulate the taste of Jamaica Blue Mountain by mixing various beans themselves, and they may not contain a single genuine Jamaica Blue Mountain bean.

The other is that some practitioners' understanding of Blue Mountain is still stuck more than 10 years in the past, believing that all genuine Jamaica Blue Mountain was bought up by Japan and that what is sold in China is not genuine Jamaica Blue Mountain No. 1. In fact, thanks to China's huge market demand, Blue Mountain has been imported normally for years. Recently, owners of Blue Mountain coffee plantations have even visited China to help Chinese consumers understand Blue Mountain beans. Blue Mountain on the Chinese market is not so rare that everything must be fake. Today's Jamaica Blue Mountain production area is larger than before, and Japan's purchasing power has weakened, so genuine Jamaica Blue Mountain is sold in China too. As long as you know how to identify it, you can buy the real thing.

Jamaica Blue Mountain Coffee Bean Processing Methods

Before 2019, Blue Mountain coffee from Clifton Farm always used the washed method to process green coffee beans. During processing, the skin and pulp are first removed, then the beans are fermented for 12-18 hours. The fermented beans are then placed in pools and moved back and forth, using the friction of the beans and the power of flowing water to wash them until smooth and clean. After washing, the beans are still wrapped in parchment with a moisture content of 50%, and must be sun-dried to bring the moisture down to 12-14%; otherwise they will keep fermenting, turn moldy, and rot. The beans are then screened and stored in dedicated warehouses.

In the 2020 new harvest season, Clifton Farm launched natural-processed Blue Mountain coffee beans for the first time, which was truly novel. Jamaica has a tropical rainforest climate, with rainy seasons from May to June and September to November each year, and the most showers in January and May. The harvest and processing season for Jamaica Blue Mountain runs from February to June each year, half of it during the rainy season, which makes natural processing clearly impractical. In addition, traditional natural processing gives unstable quality, with the result depending entirely on the weather. Furthermore, to achieve better natural quality, labor costs are higher than for washed and other methods: when coffee fruits dry on the beds, they must be turned by hand every few hours to maintain ventilation, reduce mold, and ensure even drying. Such a labor-intensive and unrewarding method was even harder to carry out in Jamaica at the time.

FrontStreet Coffee's Blue Mountain Coffee Green Bean Analysis

First, observe FrontStreet Coffee's Blue Mountain green beans. Whether natural or washed, the beans are very full, with uniform screen size, slightly pointed at both ends, and oval in shape. Seen from the side, the bean body is flat and thin, characteristic of the pure Typica variety. FrontStreet Coffee's natural-processed Blue Mountain beans appear yellow-green with more silver skin, while the washed Blue Mountain beans are blue-green with less silver skin. This is because washed beans are soaked in water for a long time during processing, separating the silver skin from the beans; when the parchment is finally removed, the outer silver skin peels off with it, leaving very little behind on the surface of washed green beans.

FrontStreet Coffee Roasting Experience

FrontStreet Coffee's Washed Blue Mountain Coffee:

Heat the roaster to 170°C, add the beans, and set airflow to 3. After 1 minute, reduce heat to 140°C and keep airflow unchanged. At 5'10", the temperature reaches 153°C, the bean surface turns yellow, the grassy smell disappears completely, and dehydration is complete. Adjust heat to 115°C and change airflow to 4. At 8'00", ugly wrinkles and black spots appear on the bean surface and the toast aroma clearly turns to coffee aroma, which can be defined as the prelude to first crack. At this point, listen carefully for the sound of first crack. At 8'12", first crack begins; reduce heat to 90°C, open the airflow fully (adjust heat very carefully, not so low that cracking stops), and discharge at 201.3°C.

FrontStreet Coffee's Natural Process Blue Mountain Coffee:

Heat the roaster to 165°C, add the beans, set heat to 130 and airflow to 3. Return to temperature at 1'32", when the roaster reads 95.8°C; keep heat unchanged. At 3 minutes, adjust airflow to 4. At 4 minutes, increase heat to 140. At 6'30", the bean surface turns yellow, the grassy smell disappears completely, and dehydration begins. At 8'36", ugly wrinkles and black spots appear on the bean surface and the toast aroma clearly turns to coffee aroma, which can be defined as the prelude to first crack. At this point, listen carefully for the sound of first crack. At 10'06", first crack begins; develop for 3 minutes after first crack and discharge at 198.5°C.

FrontStreet Coffee Cupping Report

FrontStreet Coffee conducts cupping within 8-24 hours after roasting the sample beans. FrontStreet Coffee's barista typically uses 200ml ceramic cupping bowls, marked with 150ml and 200ml measurement lines. According to SCAA standards, water TDS is around 150ppm; too low a TDS easily causes over-extraction, while too high a TDS affects mouthfeel and can cause under-extraction. Cupping water temperature is 94°C. Cupping grind size follows SCAA cupping standards, controlled so that 70%-75% passes through a No. 20 standard sieve (0.85mm). Ratio: 11 grams of coffee powder to 200ml of hot water, i.e., 1:18.18, which extracts a concentration within the golden cup range of 1.15%-1.35%. Steeping time: 4 minutes.

FrontStreet Coffee's Washed Blue Mountain Coffee Cupping:

Dry aroma: Roasted peanuts, hazelnuts, cantaloupe, chocolate

Wet aroma: Oolong tea, caramel, honey, chocolate, almonds

Flavor: Roasted nuts, chocolate, almonds, cantaloupe, honey, balanced sweet, sour, and bitter

FrontStreet Coffee's Natural Process Blue Mountain Coffee Cupping:

Dry aroma: Nuts, woody

Wet aroma: Caramel

Flavor: Berries, smoked plums, mulberries, dark cocoa, nuts, a slight fermentation sensation

FrontStreet Coffee Brewing Experience

Filter: Kono

Dose: 15g

Ratio: 1:15

Grind size: Medium-coarse (No. 20 standard sieve, 75% pass-through)

FrontStreet Coffee's segmented brewing method: 30g water for a 30-second bloom, then a small, slow flow circling from the center outward to add 100g water, showing 130g on the scale. Then wait until the coffee bed drops to the halfway level, and pour 65g with a larger flow, reaching a total water weight of 195g. After all the coffee liquid drips from the filter into the server, remove the filter to end extraction. Total brewing time is 1 minute 50 seconds.

[FrontStreet Coffee's Natural Process Jamaica Blue Mountain] The entry has brown sugar sweetness with berry acidity, nut and cocoa flavors through the middle and back, a creamy texture, and rich, distinct layers, with a finish that reveals walnut aroma.

[FrontStreet Coffee's Washed Jamaica Blue Mountain] The entry has dark chocolate and nut flavors, high cleanliness, very bright, with good body and a balanced sweet, sour, and bitter profile.

Comparing these two FrontStreet Coffee Blue Mountain No. 1 varieties, the natural process has stronger flavor layers, and its sweetness and acidity give a very comfortable feeling, while the washed Blue Mountain keeps the classic Blue Mountain character — that smooth, bright, mellow taste from the first sip to the last, with a delicate balance of sweet, sour, and bitter that takes your breath away.

FrontStreet Coffee Recommendation

FrontStreet's Jamaica Blue Mountain No. 1 sits at the top of the grading scale. It comes from the long-established Clifton estate, where coffee has been grown since around 1750 and the planting and processing area averages some 4,300 feet (1,310.64 m). A medium-dark roast best expresses Blue Mountain's famous balance, unfolding layers of nut, dark chocolate, cream caramel, and soft sweetness, with sweet, sour, bitter, and aromatic notes in harmony.

Because Blue Mountain is costly, authenticity matters. Genuine Jamaica Blue Mountain ships in the traditional wooden barrels — 15 kg, 45 kg, and 70 kg sizes — each stamped with the lot's details, and comes with the estate's certificates and proof of origin. FrontStreet roasts within five days and notes that the beans show best after resting 4-7 days from the roast date.

For pour-over, FrontStreet suggests a Kono dripper with 15 g of coffee, a 1:15 ratio, and water at 87-88°C — too hot and the cup turns bitter and ashy, too cool and it goes flat. Grind a touch coarser than for a light roast, about the texture of granulated sugar, and pour in three stages: 30 g to bloom for 30 seconds, then to 120 g with a slow, steady circling pour, then to 225 g a little faster to keep the bed from clogging and over-extracting. Blue Mountain also works beautifully in a moka pot or as espresso, and takes milk well in a latte or flat white.
