Established in 1885 and operated by the Mun family to this day, this processing facility has witnessed the evolution of Blue Mountain coffee from a local specialty to an internationally recognized premium product.

Mavis Bank is situated approximately 10 miles northeast of Kingston, the capital of Jamaica, right within the boundaries of the legally defined Blue Mountain region, and is also the government-certified official green coffee processing center. In 1920, Victor Munn founded this now-famous processing facility, which was later taken over by his nephew, Keble Munn. Notably, Keble was not only a successful coffee agricultural entrepreneur but also Jamaica’s first certified professional cupper, possessing a high level of expertise in evaluating coffee quality. To this day, Mavis Bank has become the largest coffee collection and processing hub in the entire Blue Mountain area.

The origin of Jamaican Blue Mountain No. 1 coffee — the Jamaican Blue Mountains — is located in the eastern part of the country. It spans a region about 45 kilometers in length and 20 kilometers in width, with elevations reaching up to 2,260 meters, making it the highest peak in the entire Caribbean region. The area is perpetually surrounded by a gentle blue mist, hence the name “Blue Mountains.” Uniquely, the Blue Mountain region features exceptionally well-drained, fertile soil, combined with moderate rainfall, soft cloud cover in the afternoons, and ample sunlight, creating a microclimate that is highly suitable for the growth of Arabica coffee trees. Coffee plants mature slowly in such a natural environment, which aids in the accumulation of flavor compounds, resulting in the delicate and layered taste that Blue Mountain coffee is known for.

At Mavis Bank, the processing of every batch of Blue Mountain No. 1 coffee beans is handled with great care. Farmers only harvest fully ripe red coffee cherries, which then undergo two rounds of manual sorting and floatation to ensure that only the healthiest cherries proceed to further processing. These pre-selected cherries are sent to professional wet mills where the pulp is removed before dusk, then placed in large water tanks for additional screening to remove defective beans that are over-fermented, unripe, or pest-damaged. This rigorous preliminary processing is the first line of defense to ensure the final quality of the green beans.

After depulping, the coffee beans go through mucilage removal, and then the parchment-covered beans are evenly spread on cement slabs to undergo sun drying, a process that typically lasts five days. Once dried, the parchment beans are stored in warehouses for at least ten weeks to allow for maturation and stabilization. Finally, another round of manual selection is conducted to thoroughly eliminate any visually defective beans, retaining only those that are intact in appearance and uniform in size as premium-quality green beans.

The final Mavis Bank Blue Mountain No. 1 coffee beans belong to Jamaica’s legally defined No. 1 grade, rigorously selected for bean size between 17/18 mesh and a defect rate below 2%. These beans, when medium-to-dark roasted, can fully express their intrinsic potential, showcasing an enticing profile dominated by nutty and walnut notes, accompanied by a sweet finish reminiscent of dark chocolate and caramel. With a mild acidity and full body, it is a classic choice suitable for both pour over and drip brewing.

For coffee enthusiasts who enjoy mastering the art of pour over, this Blue Mountain No. 1 is also an excellent option for experimenting with how different extraction parameters influence flavor. It is recommended to use a medium-fine grind (similar to the coarseness of granulated sugar), maintain a water temperature between 90–92°C, and pour with a steady medium stream to help balance sweetness, acidity, and body. If you wish to replicate the flavor experience of a professional café at home, pay attention to bean storage conditions to ensure freshness and achieve the best possible flavor expression.
