The coffee processing method determines the flavor direction of green beans. Among the three major categories of natural, washed, and semi-washed, the Indonesian island of Sumatra, due to its year-round humid climate, developed a unique wet-hulling method—removing the parchment layer while the bean's moisture content is still as high as 30% to 35%, leaving the green beans exposed to continue drying. This locally adapted craft shortens the fermentation period and reduces acidity, yet enhances body, and gives Mandheling its "taste of place" woven with herbal, woody, and caramel notes. Front Street Golden Mandheling is precisely made using this method, undergoing three hand-sortings and one machine-sorting, resulting in an extremely low defect rate and a clean, pure taste. This article will detail the seven steps of the wet-hulling method and explain why the distinctive "sheep-hoof" appearance of wet-hulled beans should not be considered a defect. [more…]

Have you ever heard the term "frog bean"? It doesn't refer to green coffee beans that look like frogs, nor to the "goat hoof" beans caused by Indonesia's wet-hulling process, but rather to coffee beans that have received Rainforest Alliance certification—because the logo of this certification is a red-eyed tree frog. The Rainforest Alliance was founded in 1987 and is an international non-profit organization operating at the intersection of agriculture, forestry, and business. Its certification focuses on whether farms adopt sustainable agriculture and natural resource management practices, with a particular requirement that coffee be grown under the shade of native forest trees using traditional farming methods. Coffee beans that pass certification may use the Rainforest Alliance logo and gain priority sales channels. However, certification does not necessarily mean the flavor is outstanding; it mainly evaluates the growing environment. The Blue Mountain coffee currently sold by Front Street Coffee is the only bean it offers with this certification, and within the Blue Mountain region, only Clifton Mount Estate holds the certification. Let's now take a closer look at frog beans, the Rainforest Alliance, and the flavor performance of Front Street Coffee's Blue Mountain. [more…]
