Jamaican Blue Mountain GeishaCoffee Bean Intro:
What a year of surprises it has been this year. In the last century, the definition of great coffee was based on Blue Mountain coffee, but in this century, it’s all about the preciousness of Geisha coffee. So what happens when the strengths of Blue Mountain and Geisha come together? That’s right — this year, the Jamaican Blue Mountain region has introduced a Geisha coffee.
Blue Mountain Geisha
Until 2019, the only Blue Mountain coffee available in overseas markets was washed Typica. It was precisely because of this single processing method and coffee variety that Blue Mountain coffee maintained consistently high quality over the decades. Its balanced and mellow flavor appeals to some coffee enthusiasts. Then, in 2020 (news from 2019), Blue Mountain first launched a natural-processed Blue Mountain No. 1 coffee, followed by the introduction of Blue Mountain Geisha.

As to why Blue Mountain, known for its consistency over the years, has started innovating recently — it turns out there were early signs. There were reports that Jamaica had been experimenting with planting Bourbon varieties. Upon hearing this, our team at Priory Street discussed the reasons behind Jamaica’s move. Before the rise of bright, fruity acid-forward coffees, the public’s perception of coffee was dominated by rich, bold flavors, such as those found in traditional Mandheling or Colombian coffee. In those days, traditional Blue Mountain coffee reigned supreme, like the king of all birds, with its clean, mellow, and balanced flavor setting the benchmark for future imitations. Alongside Hawaii Kona, it was hailed as the “king and queen” of the coffee world.
But times have changed — first came the fruit-bomb Yirgacheffe, then the world-renowned Panama Geisha. Together, they sparked a global wave of appreciation for vibrant acidity in coffee. Faced with this trend, traditionalist Blue Mountain farmers felt their coffee’s status was being challenged and began to innovate gradually. This year’s new natural-processed Blue Mountain and Blue Mountain Geisha are clear evidence of this shift.
Priory Street Coffee was also among the first to secure a batch of Blue Mountain Geisha. Like traditional Blue Mountain No. 1, exported coffee is packaged in wooden barrels. This particular limited batch comes from the Clifton Estate, and the barrel bears the Rainforest Alliance certification (currently, only Clifton Estate in the Jamaican Blue Mountain region holds this certification).
It’s important to understand that coffee trees are plants — you can’t just transplant them from one region to another and expect success. This involves the adaptability and stability of new species to a new environment. To grow coffee with great flavor, you need excellent agronomic expertise, time for acclimatization, a suitable growing environment, and ample experience in coffee processing. It’s evident that Blue Mountain initiated plans to cultivate other varieties years ago. After years of breeding and flavor refinement, the Geisha variety — prized for its floral and fruity notes — was discovered by Panama’s Hacienda La Esmeralda in 2004. Over a decade later, it has spread across most coffee-growing regions, even reaching Yunnan. This year, Jamaica’s limited release of Blue Mountain Geisha shows just how confident they are in this new offering.
Blue Mountain Geisha Processing Method
Blue Mountain Geisha still employs Jamaica’s signature washed processing. The process begins with removing the pulp and skin, followed by fermentation for 12–18 hours. The fermented beans are then placed in tanks and agitated to remove the mucilage using friction and water flow, resulting in clean and smooth beans. After washing, the beans remain encased in their parchment layer with a moisture content of around 50%. They must be sun-dried until the moisture level drops to 12–14%; otherwise, further fermentation, mold, and spoilage can occur. After drying, the beans are sorted and stored in specialized warehouses.
Observing the green beans, they are vibrant green, slightly elongated, and exhibit an extremely low defect rate — a testament to the maturity of their processing technique and quality control.
Priory Street Coffee Roasting Analysis
For this batch of Blue Mountain Geisha, our roasters faced a dilemma: should they highlight the Blue Mountain profile or the Geisha profile? If they emphasized the Blue Mountain characteristics, what would be the point of using the Geisha variety? But if they highlighted the Geisha profile, wouldn’t that conflict with the prestige of the Blue Mountain name? To address this, our roasters first roasted two versions — one medium roast with traditional rich and bold flavors, and one light roast with pronounced fruity and floral notes. After several fine adjustments, they ultimately decided on a modified light roast curve that accentuates the Geisha’s floral and fruity acidity.
Charge temperature: 180°C, flame power: 130, air vent: 3. Turning point at 1’32”, with drum temperature at 97°C and flame power unchanged. At 3 minutes, air vent adjusted to 4, and at 4 minutes, flame power increased to 140. At 153.5°C, the bean surface turns yellow and grassy notes disappear, entering the drying phase. At 8’36”, the beans show wrinkled surfaces and dark streaks, with the toastiness clearly transitioning into coffee aroma — marking the prelude to first crack. Carefully listen for the first crack, which begins at 9’31”. Development after first crack lasts 1’28”, and the beans are dropped at 192°C.
Priory Street Coffee Cupping
Eight hours after each roast, samples are cupped using 200ml standard cupping bowls, with a grind size passing through a 20-mesh sieve at 70%–75% and a coffee dose of 11g. Water TDS is 120ppm, and temperature is 94°C. Dry aroma is assessed first, followed by pouring water to fill the bowl. Wet aroma is evaluated, and after 4 minutes, the crust is broken and removed for flavor evaluation.
