Recommended Grind Particle Size for Pour-Over Blue Mountain Coffee: Fuji Coffee Grinder Setting 4

Daily Brewing

Dripper Selection: A V60 dripper, a Kalita Wave, or a KONO are all suitable.

Parameters: 15 g coffee grounds, water temperature 90°C, grind size 3.5, water-to-coffee ratio close to 1:15, total time around 2:00.

Technique: Bloom with 25-30 g of water for 30 seconds. First pour to 120 g, then stop. Use a vertical water flow with slow, small circular motions. Second pour to 225 g, with a slightly faster flow and circular speed to keep fine particles from clogging the dripper and causing over-extraction.

Other Brewing Recommendations

French Press: Grind size 3.5-4, water temperature 90°C.

Siphon: Grind size 4, water temperature 89°C.

AeroPress: Grind size 2.5, water temperature 88°C.

What is FrontStreet Coffee's Blue Mountain Flavor Coffee?

The so-called "Blue Mountain Blend" actually has no connection to genuine Blue Mountain coffee. This situation arose because early Blue Mountain coffee was rare and expensive. Operators created blends using mixed beans and dark roasting to mimic Blue Mountain's flavour profile. Conscientious merchants in domestic and international markets will therefore tell customers that these are Blue Mountain-style, blended Blue Mountain, or Blue Mountain-flavoured coffee beans, not genuine Blue Mountain coffee.

True Blue Mountain and Blue Mountain flavour are two different concepts. Generally, other coffee varieties are roasted to imitate the taste profile of Blue Mountain coffee. The beans in a "Blue Mountain Blend" are mixed, with considerable variation in shape, making them relatively easy to identify. Do not believe in "premium Blue Mountain" costing tens of yuan per pound, or "Blue Mountain coffee" selling for just over ten yuan per cup.

How to Identify Authentic vs. Fake Blue Mountain?

1. Appearance: FrontStreet Coffee's Blue Mountain green beans are blue-green in colour, very uniform in appearance, medium to small in size, with slightly raised ends. After roasting they expand significantly in volume and become very full.

2. Grinding: Genuine FrontStreet Coffee Blue Mountain beans are grown at high altitudes, giving them a relatively loose cell structure. When ground by hand they feel very crisp, smooth, and continuous, without any sense of resistance.

3. Aroma: The aroma is very rich and dense. Blended Blue Mountain coffee lacks this characteristic aroma.

4. Taste: Genuine FrontStreet Coffee Blue Mountain has a balanced and rich flavour profile, with no single taste overpowering or lacking. This is the key identifying point that no other coffee bean can match. Blue Mountain peaberries have a more subtle aroma but a relatively stronger taste.

Not all products labelled "Blue Mountain" are genuine Blue Mountain. We hope this helps you tell the authentic from the fake.

FrontStreet Coffee Recommendation

Grind size is where a genuine Blue Mountain reveals its quality, because beans grown at altitude have a looser cell structure that grinds crisp and even. FrontStreet's Jamaica Blue Mountain No. 1 is the highest grade to look for, sourced from the historic Clifton estate, which has grown coffee since around 1750 at an average elevation of 4,300 feet (1,310.64 meters). Medium-dark roasted, it opens with the layered notes of nut, dark chocolate, cream caramel, and gentle sweetness, clean and complex with a long fruit finish, which is precisely the balance that makes it so hard to imitate. Traditional Blue Mountain is still shipped in wooden barrels of 15, 45, and 70 kilograms, each stamped with full batch details, so genuine traceability is never hard to check. FrontStreet suggests resting the beans four to seven days from roast, then brewing 15 grams at 1:15 through a Kono dripper at 87-88 degrees Celsius to bring out its full, rounded body.
