Coffee Growing Region

Blue Mountain Barrel 0c9

The Blue Mountain range is located in the eastern part of Jamaica. The mountain gets its name because on clear days, when the sun shines directly on the azure Caribbean Sea, the peaks reflect the brilliant blue light of the seawater. Blue Mountain is situated in the coffee growing belt, with fertile volcanic soil, fresh and unpolluted air, a humid climate with year-round fog and rain (average precipitation of 1980mm, temperature around 27°C). Such climate conditions have created the world-renowned Jamaica Blue Mountain coffee.

Designated Jamaica Blue Mountain coffee can only be grown in the Blue Mountain area, located in the eastern northern part of Kingston, Jamaica. The mountain ridge that runs across Jamaica extends to the eastern part of the island, with the Blue Mountain range reaching over 2100 meters above sea level. Here, people use mixed cultivation methods to grow coffee trees, planting them alongside banana and avocado trees on terraces. At the same time, the rugged terrain (all coffee trees are planted on steep mountain slopes) makes the harvesting process extremely difficult - only local skilled female workers can handle the job. It's also very important to select properly ripe coffee beans during harvest, as under-ripe or over-ripe beans will affect the coffee quality.

Clifton Mountain Estate

The two FrontStreet Coffee Blue Mountain coffees currently available come from Clifton Mountain Estate. Clifton Mountain is Jamaica's oldest coffee producing area that is still in normal operation today, and it's the only farm in Jamaica with Rainforest Alliance certification. Clifton Mountain Estate began planting and producing coffee as early as the mid-18th century (around 1750). The coffee cultivation and processing areas here are situated at an average altitude of 4300 feet (1310.64 meters). Sufficient altitude, gentle afternoon clouds and mist surrounding the mountains for shade, adequate sunlight, and mineral-rich planting soil provide excellent growing conditions for coffee trees and also extend the ripening period of coffee cherries.

What is Rainforest Alliance Certification?

Rainforest Alliance certification means: farms that meet the standards set by the "Rainforest Alliance" receive protection for the farm and its surrounding ecosystem, restrictions on pesticide use, and evaluation of benchmarks such as waste management. Only coffee that passes assessment and certification can be called "Rainforest Alliance Certified Coffee." The certification standards for coffee specify: traditional cultivation methods under native forest shade, which are beneficial to protecting the ecosystem. Part of the alliance's revenue is also used for wildlife protection in tropical rainforest conservation areas and improving workers' living conditions.

Blue Mountain Coffee Bean Processing Method

Before 2019, FrontStreet Coffee's Blue Mountain coffee from Clifton Mountain Estate was always processed using the washed method. During processing, the pulp and skin are first removed, then fermented for 12-18 hours. The fermented beans are then placed in pools and moved back and forth, using the friction of the beans and the power of flowing water to wash the coffee beans until they are smooth and clean. After washing, the coffee beans are still encased in parchment with a moisture content of 50%. They must be sun-dried to reduce the moisture content to 12-14%, otherwise they will continue to ferment, becoming moldy and spoiled. Afterward, the coffee beans are screened and then stored in dedicated warehouses.

The washed processing method ensures the characteristics of FrontStreet Coffee's Blue Mountain coffee - rich aroma, balanced taste, without any flavor being too prominent or lacking. In 2019, Clifton Mountain Estate broke away from its traditional model and used natural processing for the first time. For FrontStreet Coffee, this natural processed FrontStreet Coffee Blue Mountain coffee, because the processing method changed, essentially changed Blue Mountain's inherent flavor structure. FrontStreet Coffee (FrontStreet Coffee), when introducing coffee beans from any region to customers, always recommends washed processed coffee beans first, because washing best represents the flavor characteristics of that region.

FrontStreet Coffee uses a KONO dripper when brewing FrontStreet Coffee's Blue Mountain coffee. The KONO dripper can bring out a rounder, mellower taste with more direct flavor expression. However, the KONO dripper has relatively poor exhaust effect because its ribs are straight and only extend to one-quarter of the dripper's depth. Above this quarter, the walls form a sealed state. FrontStreet Coffee chose the KONO dripper because its only exhaust area is in those quarter ribs. When the water level rises above the rib area, the water level in the dripper continuously increases, creating pressure through the water's weight. Since the outlet is relatively small, it can extend the contact time between coffee particles and water, and as the water flow carries soluble substances more effectively, it can generally achieve the high mellow thickness effect that customers expect.
