Blue Mountain coffee is produced in the Blue Mountains of Jamaica at elevations between 910 and 1,700 meters. The variety is Typica, and it is known for its balanced acidity, sweetness, and bitterness, full and solid body, long-lasting sweet aftertaste, and absence of burnt bitterness. Because annual production is limited, authentic Blue Mountain No. 1 coffee beans in China usually sell for 150 to 400 yuan (100 to 200 grams), while products labeled "Blue Mountain flavor" or "Blue Mountain blend" are not true Blue Mountain coffee. This article systematically introduces the methods baristas use to identify authentic Blue Mountain No. 1 from perspectives such as the wooden barrel and certificate, bean size and uniformity, appearance characteristics, and raw bean color. It also compares the flavor performance of washed and natural processing methods and shares Front Street Coffee's brewing parameters and techniques to help enthusiasts build a clear identification framework.
