Golden Mandheling is a highly respected name in the coffee world, yet few people have actually tasted the authentic version. The market is flooded with all kinds of coffee beans marketed under the banner of "Golden Mandheling," with prices varying widely from high to low, making it difficult for consumers to tell them apart. This article will walk you through the origins of Golden Mandheling—it is not simply about "large beans and few defects," but rather stems from the strict standards of Indonesia's PWN green bean company.

At the same time, Front Street Coffee will share how to distinguish the genuine article through certificates and burlap sack numbers, along with hand-brewed flavor notes for PWN Golden Mandheling, to help you make a wiser decision when purchasing.

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…]

Following our previous discussion of the two major processing methods—natural and washed—this time we turn our attention to several post-harvest processes that fall between them: wet-hulled, semi-washed, pulped natural, and honey processing. How is each of these methods carried out? And what impact do they have on coffee flavor? We'll still start with the structure of the coffee cherry: from the outside in, the fruit consists of the outer skin, pulp, mucilage, parchment layer, silver skin, and the coffee bean seed itself. The core goal of all processing methods is simply to remove the outer layers and extract the seed. However, differences in the method, timing, and degree of removal lead to vastly different results in the cup. This article will break down these processing methods one by one—their procedural details, flavor tendencies, and the subtle connections between them—to help coffee enthusiasts more clearly understand the key role processing plays in shaping flavor.

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…]
