Jamaica Blue Mountain No.1: The Story of Conastale Estate

Ever wondered what makes Jamaica Blue Mountain No.1 coffee so legendary — and so hard to find? This isn’t just about a famous name. It’s about a very specific region, a tightly controlled process, and a coffee that balances sweetness, acidity, and body unlike almost any other. If you’ve heard stories about its rarity or debated whether you’ve ever had the real thing, this is where those answers begin.

Jamaica Blue Mountain No.1 coffee from Conastale Estate is grown at the highest elevation in the Blue Mountains, borders a national park, and is produced through a unique supply chain: local farmers sell cherries to Sharphouse Coffee Trading, which sends them to the B.M.C.P factory for processing. The beans are then exclusively imported by Japan’s ATAK Trading. Less than 2,500 tonnes of true Blue Mountain coffee are produced annually worldwide, and Conastale is among the top producers.

What Is Conastale Estate?

Conastale Estate is not just a name on a bag — it’s both a historic coffee farm and a modern brand. Located at the heart of Jamaica’s Blue Mountain region, it sits at the highest elevation of any Blue Mountain coffee farm and borders Jamaica’s largest national park and forest reserve. It’s recognised as the highest-altitude Blue Mountain coffee estate.

The estate dates back to 1801, making it one of the oldest documented coffee farms in the region. Historical records track ownership across three generations: Colin McClarty (1801–1825), his son Alexander McClarty (1825–1842), and Alexander Campbell (1825–1842). After 1842, the estate vanished from official records until its revival by Sharphouse Coffee Trading in the modern era.

The Modern Revival of a Historic Brand

Conastale as a brand was brought back to life by Sharphouse Coffee Trading, a Jamaican company operated by the Sharphouse family — Florence, Richard, and Jason Sharphouse. They source fresh Typica coffee cherries from farms near the original Conastale Estate and send them to the B.M.C.P factory for washing, drying, and milling. The beans are exported under exclusive rights held by Japan’s ATAK Trading, which also invested in the B.M.C.P factory.

Before its revival, all that remained of the original estate was a ruined coffee mill. Today, Conastale is a premium coffee brand known for producing some of the most sought-after Jamaica Blue Mountain No.1 beans in the world.

What Makes Jamaica Blue Mountain No.1 So Special?

Jamaica Blue Mountain No.1 coffee is renowned for its balance. Unlike bright African coffees or heavy-bodied dark roasts, it delivers a smooth, rounded profile with no sharp edges. Expect a cup with fine acidity, a full body, and a sweet, creamy finish. Flavour notes often include hints of nuts, chocolate, caramel, honey, and mild fruit — all in harmony.

The secret lies in the growing conditions: high altitude (over 1,200 metres), volcanic soil, consistent rainfall, and cool temperatures that slow ripening and develop complex sugars. The strict grading system for Blue Mountain No.1 requires beans to be 17/18 mesh (96% or more), with minimal defects.

Conastale Estate beans are Typica variety, with over 96% falling within the 17/18 mesh size — meeting the top grade. These are the same beans that helped make Sharphouse the top Blue Mountain No.1 exporter from Jamaica in 2007, with ATAK Trading becoming Japan’s largest importer that year.

How Is Blue Mountain No.1 Processed and Graded?

Blue Mountain No.1 coffee is processed using traditional washed methods at the B.M.C.P factory. The beans are carefully sorted by size and density, with only Grade 1 (17/18 mesh) beans qualifying as No.1. This grade ensures uniform bean size, fewer defects, and a cleaner cup.

The processing includes fermentation, washing, and sun drying on patios — all meticulously managed to preserve the delicate flavours. The beans are then stored in traditional wooden barrels for export, another hallmark of genuine Blue Mountain coffee. These barrels are often shown in certification documents and are a sign of authenticity.
