The Blue Mountain Coffee Growing Area: Boundary, Parishes and Altitude

The Blue Mountain coffee area is defined by a boundary written into Jamaican law. The First Schedule of the Jamaica Agricultural Commodities Regulatory Authority Regulations, 2018 describes it as a loop of fifteen named places in eastern Jamaica, and coffee grown inside that loop is the only coffee the regulations call Jamaica Blue Mountain.

How does Jamaican law draw the Blue Mountain area?

The 2018 regulations, published in the Jamaica Gazette on March 2, 2018, define the "Blue Mountain area of Jamaica" by reference to their First Schedule. That schedule starts at Skibo and runs east-south-east to Swift River, then to Chelsea and Durham (Samba Hill), south-east to Belleview, along the western slope of the John Crow Mountains to Cedar Grove, west to Font Hill, north-west to Ramble, west to Good Hope, north-west to Dallas and Industry Village, north and north-west to Maryland and Golden Spring, north to Brandon Hill, north-east to Tranquility, and back to Skibo.

The wording is close to the schedule in the older Coffee Industry Regulations, 1953, which used the same idea of a described Blue Mountain area. The 1953 rules went one step further in the definition itself: Blue Mountain coffee had to be grown in the area and processed at one of the coffee works listed in the schedule. The 2018 definition is shorter, but processing is still controlled through licensing of coffee works and record-keeping on where their coffee came from.

Which parishes does the area cover?

Most descriptions name parishes rather than boundary points. A 2023 peer-reviewed paper in Insects describes Blue Mountain coffee as grown in St Thomas, St Andrew and Portland. Wikipedia and WIPO's case study list those three plus St Mary. The difference matters less than it seems: the legal line does not follow parish boundaries, so being in one of these parishes does not make a farm part of the Blue Mountain area, and the regulations never use parish names to define it.

For a buyer, a named estate, works or district on a label is more meaningful than a parish. Familiar place names in the coffee trade, such as Mavis Bank in St Andrew, sit inside the Blue Mountain range, while a label that only says "Jamaican mountain coffee" tells you nothing about which side of the line it was grown on.

What altitude is Blue Mountain coffee grown at?

The figure most often repeated is 3,000 to 5,500 feet (roughly 910 to 1,680 meters). WIPO's case study, drawing on the Coffee Industry Board's account, gives that band, and Wikipedia repeats it while noting it reflects tradition. Other sources give different numbers: the 2023 Insects paper describes Blue Mountain coffee as grown at about 500 to 2,000 meters, and one of its two study sites, a Blue Mountain farm at Rosehill in St Andrew, sat at 960 meters.

The reason for the spread is that elevation is not the legal test. Coffee inside the boundary at a lower elevation is still, by definition, grown in the Blue Mountain area; coffee outside it at 5,000 feet is not. Treat the 3,000-to-5,500-foot range as a description of where most Blue Mountain coffee grows, not as a rule.

What is the growing environment like?

The Blue Mountains run between Kingston and Port Antonio and reach about 2,256 meters (7,402 feet) at Blue Mountain Peak, among the highest points in the Caribbean. Wikipedia's summary describes the climate as cool and misty with high rainfall, and the soils as rich and well drained. Farms are mostly small and steep: the Insects paper describes Jamaican coffee as grown on steep slopes in the central mountains, with more than 80% of farms run by smallholders who rely on manual labor.

That terrain shapes how the coffee is handled. WIPO's case study describes reapers selecting ripe red cherries, wet coffee reaching an authorized processing facility within 24 hours of pulping, sun drying, and a rest of at least eight weeks before hulling and hand sorting. It is a washed coffee tradition, and the short distance between farm and pulpery is one reason the regulations put so much weight on licensed coffee works.

What challenges does the region face?

Pests and weather are recurring problems. The coffee berry borer was detected in Jamaica in 1978, according to the Insects paper, which found no significant difference in borer activity between its Blue Mountain and High Mountain study farms. After Hurricane Sandy in 2012, field officers reported a marked flare-up of coffee leaf rust; the Jamaica Gleaner, citing IICA, put 2012–13 losses at about US$5 million, around 25% of industry earnings. More recently, the Jamaica Coffee Exporters Association blamed adverse rain during the 2023/24 harvest for losses of an estimated 50,000 boxes.
