What Is Jamaica Blue Mountain Coffee? The Real JABLUM Brand

If you’ve ever asked, “What’s so special about Jamaican Blue Mountain coffee?” you’re not alone. For decades, coffee enthusiasts have sought out this legendary bean—but few truly understand why it commands such reverence, or which producers actually meet the strict standards behind the name. With high prices, limited availability, and countless imitations, knowing what qualifies as real Blue Mountain coffee is more important than ever.

The short answer? True Jamaica Blue Mountain Coffee comes only from a specific high-altitude region in eastern Jamaica, is grown above 1800 meters, and is certified by the Jamaica Coffee Industry Board. The brand JABLUM, made by Mavis Bank Coffee Factory—a company over 150 years old—produces 40% of all Jamaica’s official Blue Mountain coffee.

Where Blue Mountain Coffee Comes From

Jamaica Blue Mountain Coffee grows in the Blue Mountains of eastern Jamaica. The name comes from the blue-tinted haze that surrounds the peaks when sunlight refracts off the Caribbean Sea. This region offers near-perfect growing conditions: rich volcanic soils, consistent rainfall, cool temperatures with large diurnal shifts, and elevations that slow cherry maturation and build complex sugars.

However, not all coffee grown in the Blue Mountains earns the name. Only beans cultivated at elevations above 1800 meters—within the parishes of Saint Andrew, Saint Thomas, and Portland—can be certified as Jamaica Blue Mountain Coffee. These areas form the three official coffee-growing regions of the Blue Mountain range.

The History Behind the Bean

Coffee arrived in Jamaica in 1725, brought by French officer Sir Nicolas Lawes, who planted the first trees in Saint Andrew. Later, Haitian coffee farmers fleeing unrest introduced more expertise. Saint Andrew soon became one of the three main coffee-producing regions, alongside Portland and Saint Thomas.

After slavery ended in 1838, many freed workers moved to the mountains to grow and export coffee—especially to Britain. By the 1930s, Jamaica’s coffee production peaked at around 15,000 tonnes annually. But quality declined by the mid-20th century, leading international buyers to back away. In response, the Jamaican government established the Coffee Industry Board to restore standards.

Japan played a pivotal role in the coffee’s revival. Starting in 1969, Japanese investors offered financial support and guaranteed purchases. This helped rebuild production and processing quality—but also led to a lopsided trade relationship. Today, Japan imports around 90% of Blue Mountain coffee, leaving just 10% (about 3,500 70kg barrels) for the rest of the world.

How JABLUM Became a Leading Blue Mountain Brand

JABLUM is the commercial brand of Mavis Bank Coffee Factory, Jamaica’s oldest and largest processor of Blue Mountain beans. With over 150 years of history, Mavis Bank produces roughly 40% of all certified Jamaica Blue Mountain Coffee. Their JABLUM label is one of the most recognised worldwide.

The company adheres to rigorous quality control mandated by the Jamaica Coffee Industry Board. Every step—from seedling selection to fertilisation, harvesting, wet-processing, roasting, and packaging—is closely monitored. Only beans that pass strict inspection receive official “Blue Mountain Coffee” certification.

JABLUM coffee is known for its low caffeine content (less than half that of other coffees) and balanced flavour profile. Notes include creamy textures, smooth mouthfeel, and a harmonious blend of sweetness, acidity, bitterness, and aroma, with a long aftertaste.

Why the Traditional Wooden Barrel Packaging Matters

Jamaica is one of the last countries still using traditional wooden barrels to ship coffee. Blue Mountain beans are exported almost exclusively in 15kg, 45kg, or 70kg wooden casks. This distinctive packaging isn’t just tradition—it’s a key mark of authenticity.

With Jamaica’s total annual coffee production at just around 40,000 60kg bags (roughly 2,400 metric tonnes), the supply of certified Blue Mountain coffee remains extremely limited. That makes JABLUM, as one of the primary certified producers, especially prized among collectors and connoisseurs.
