Jamaican Blue Mountain Coffee
Jamaican Blue Mountain Coffee or Jamaica Blue Mountain Coffee is a classification of coffee grown in the Blue Mountains of Jamaica. The best lots of Blue Mountain coffee are noted for their mild flavour and lack of bitterness. Over the last several decades, this coffee has developed a reputation that has made it one of the most expensive and sought-after coffees in the world. Over 80% of all Jamaican Blue Mountain Coffee is exported to Japan. In addition to its use for brewed coffee, the beans are the flavor base of Tia Maria coffee liqueur.
Jamaican Blue Mountain Coffee is a globally protected certification mark, meaning only coffee certified by the Coffee Industry Board of Jamaica can be labeled as such. It comes from a recognised growing region in the Blue Mountain region of Jamaica, and its cultivation is monitored by the Coffee Industry Board of Jamaica.
The Blue Mountains are generally located between Kingston to the south and Port Antonio to the north. Rising to 2,300 metres (7,500 ft), they are some of the highest mountains in the Caribbean. The climate of the region is cool and misty with high rainfall. The soil is rich, with excellent drainage. This combination of climate and soil is considered ideal for coffee.
The Coffee Industry Regulation Act 
The Coffee Industry Regulation Act specifies what coffee may use the Blue Mountain label. Additionally, it restricts the use of the Blue Mountain trademark to those authorized by the Coffee Industry Board. Broadly speaking, coffee harvested from the parishes of Saint Andrew, Saint Thomas, Portland and Saint Mary may be considered Blue Mountain coffee. The specific boundaries are defined as follows:
- Starting at Skibo and proceeding in an east-south-easterly direction to Swift River;
- thence east-south-easterly to Chelsea;
- thence east-south-easterly to Durham (Samba Hill);
- thence south-easterly to Belleview;
- thence south-easterly along the western slope of the John Crow Mountain to Cedar Grove;
- thence westerly to Font Hill;
- thence north-westerly to Ramble;
- thence westerly to Good Hope;
- thence north-westerly to Dallas;
- thence north-westerly to Industry Village;
- thence north-westerly to Maryland;
- thence north-westerly to Golden Spring;
- thence northerly to Brandon Hill;
- thence north-easterly to Tranquility;
- thence east-north-easterly to Skibo.
Traditionally, only coffee grown at elevations between 3,000 and 5,500 feet (1,700 m) could be called Jamaica Blue Mountain. Coffee grown at elevations between 1,500 and 3,000 feet (910 m) is called Jamaica High Mountain, and coffee grown below 1,500-foot (460 m) elevation is called Jamaica Supreme or Jamaica Low Mountain. (All land in Jamaica above 5,500 feet (1,700 m) is a forest preserve, so no coffee is grown there.)
Classifications of Blue Mountain Coffee 
As with most other varieties of coffee, there are several grades assigned to different lots, based on factors such as size, appearance, and defects allowed.
The Coffee Industry Regulations Act allows for five classifications :
- Blue Mountain No. 1 - 96% of beans must have a screen size of 17/20. No more than 2% of the beans may have significant defects.
- Blue Mountain No. 2 - 96% of beans must have a screen size of 16/17. No more than 2% of the beans may have significant defects.
- Blue Mountain No. 3 - 96% of beans must have a screen size of 15/16. No more than 2% of the beans may have significant defects.
- Blue Mountain Peaberry - 96% of beans must be peaberry. No more than 2% of the beans may have significant defects.
- Blue Mountain Triage - Contains bean sizes from all previous classifications. No more than 4% of the beans may have significant defects.
