The Origin of Blue Mountain Coffee and How to Brew It with Flannel for the Best Taste

Flannel Drip Brewing Method

Flannel drip is a well-known technique that uses a flannel cloth, a single-sided velvet material, instead of a paper filter cup. The extraction principle is the same as paper drip, but filtration is faster, so brewing a large batch does not take long, which makes the method well suited to bigger single brews. With small doses, though, the results vary considerably depending on how you pour, which makes flannel more demanding for the person brewing.

The pores in flannel are larger than those in paper, so more of the coffee's components pass through. Paper filters block oils, for example, while flannel lets them into the cup. That oily texture is the particular charm of flannel drip compared with paper drip.

Filter Maintenance

Caring for the flannel filter matters. New cloth carries a paste-like residue that must be boiled off in water. A used filter should first be rinsed in clean water to remove coffee grounds, then stored damp, either in a plastic bag or soaked in water.

Flannel gradually clogs with use, so keep an eye on the flow rate during regular brewing. If the flow slows down, adjust by grinding coarser or reducing the dose of coffee.

Daily Brewing

Filter cup options: V60, Kalita Wave, and KONO are all suitable.

Jamaica Blue Mountain Coffee

Mention coffee and many friends will immediately say, "Give me a cup of Blue Mountain." FrontStreet Coffee's Jamaica Blue Mountain Coffee is known for its high quality, limited production, and long history, and even people who have never tried specialty coffee have heard of it. The market is crowded with "Blue Mountain Coffee," "Blue Mountain Flavor Coffee," and "Blue Mountain Blend," which can be confusing. Not every product with "Blue Mountain" in its name is the real thing, and it is easy to end up drinking a counterfeit. So how do you tell genuine Blue Mountain apart? First, let's look at what FrontStreet Coffee's Jamaica Blue Mountain Coffee actually is.

History of Jamaica Blue Mountain Coffee

Coffee has grown in Jamaica since the 18th century. In 1717, King Louis XV of France ordered coffee planted there. In the mid-1720s, Jamaica's Governor Sir Nicholas Lawes imported Arabica seeds from Martinique and began promoting cultivation in the St. Andrew region. Coffee trees took hold in Jamaica and were planted in the Blue Mountains, and the crop was later divided into grades: high-altitude Jamaica Blue Mountain Coffee, High Mountain Coffee, and Jamaica Coffee, with each grade carrying a different price.

Growing Altitude

The Blue Mountains lie in eastern Jamaica. They take their name from the way the peaks reflect the blue light of the Caribbean Sea on clear days. The highest peak reaches 2,256 meters, the tallest in the Caribbean and a famous tourist destination. The area sits within the coffee belt, with fertile volcanic soil, clean air, and a humid climate of year-round fog and rain (average rainfall of 1,980 mm and a temperature around 27°C). Those conditions have created the world-renowned Jamaica Blue Mountain Coffee, and with it the world's highest-priced coffee.

Brewing Parameters

15g coffee grounds, water temperature 86°C, grind size 4, water-to-coffee ratio close to 1:14, total time around 2:00.

Brewing Technique

Bloom with 25-30g of water for 25 seconds; pour to 120g and stop. Use a vertical water flow with small, slow circles. For the second pour, go to 225g with a slightly faster flow and faster circling, so that coffee particles do not clog the filter and cause over-extraction.

FrontStreet Coffee Recommendation

For the truest expression of the style, FrontStreet Jamaica Blue Mountain No.1 is the reference. It is the highest grade of Jamaica Blue Mountain coffee, sourced from the historic Clifton Mount estate, where coffee has been grown and processed since around 1750. The estate sits at an average of 4,300 feet (1,310.64 meters), and the altitude, the mild afternoon cloud cover that shades the trees, the ample sunlight, and the mineral-rich soil all lengthen the ripening of the cherry. The coffee is medium-dark roasted, so it shows the classic Blue Mountain balance: cream, caramel, chocolate, nuts, and honey, with a gentle fruit note. It is smooth and rounded on entry, sweet through the middle, and clean and long on the finish, with hardly any bitterness.

Blue Mountain is versatile. For pour-over, use a 1:15 to 1:16 ratio, water at 85-88°C, and a medium-coarse grind, which brings out the creamy, caramel, and nutty notes while keeping the soft, bright acidity. FrontStreet Coffee suggests a KONO dripper for extra body, 15g of coffee rested 4-7 days from the roast date, a grind a little coarser than for light roasts (roughly white sugar), 87-88°C water, and a 1:15 ratio, poured in three stages: 30g to bloom for 30 seconds, then to 120g, then to 225g.

If you prefer a richer cup, the same bean works in a Moka pot: grind a little finer than for pour-over, start with hot water in the chamber, heat over medium-low, and take the pot off the heat as soon as the coffee finishes flowing. The Moka pot intensifies the chocolate, caramel, and nutty notes and makes the body thicker, while the signature balance remains, and it holds up beautifully with milk in a latte or a flat white.
