Jamaica Blue Mountain is grown in a legally defined zone in the Blue Mountains of eastern Jamaica, between roughly 900 and 1,700 metres. It is among the most expensive coffees in the world, and it is worth being clear about why.
The profile
Exceptionally clean, mild and balanced. Mild acidity, medium body, a smooth sweetness, and — the quality most often cited — a complete absence of bitterness or harshness.
It is not a dramatic coffee. Nobody describes Blue Mountain as tasting of blueberry or jasmine. What it offers is refinement and balance, which is a genuine achievement and a quieter one.
Why it costs what it does
Tiny production from a small legally bounded area on steep, difficult terrain.
High labour costs relative to most origin countries.
Enormous demand from Japan, which has historically bought the majority of the crop and is prepared to pay.
Reputation, which is doing a lot of the work in the price.
Authenticity
The Jamaica Coffee Industry Board certifies genuine lots, traditionally shipped in wooden barrels rather than sacks. Look for certification.
“Blue Mountain style” and “Blue Mountain blend” are marketing phrases that do not mean the coffee came from the zone.
An honest assessment
It is a very good coffee. Blind against an outstanding Ethiopian, Kenyan or Colombian at a quarter of the price, most specialty drinkers would not rank it first. Its balance is its virtue, and balance is harder to sell than fireworks.
Brewing it
Medium roast, filter, gentle extraction. Its subtlety does not survive a very light roast or an aggressive brewer.
