Recently, a social media post in which a user brewed drip coffee using a face mask instead of filter paper sparked heated discussion.

In the mainstream pursuit of fresh coffee, Aged Mandheling stands out uniquely as an "expired" coffee. This special coffee originating from Sumatra, Indonesia, first acquired its unique flavor by accident during long sea voyages in the colonial era, and later evolved into a standardized aging process.

We usually seek out freshly roasted coffee beans, but Aged Mandheling is an exception—it is actually sought after precisely for being "expired." Behind this lies an accidental story from Indonesia's Dutch colonial period: when coffee beans were shipped across the ocean to Europe, the long sea voyage and exposure to sea breezes unexpectedly gave rise to a mellow sweetness and lingering finish reminiscent of Pu'er tea. Today, the production of Aged Mandheling has long been standardized: it requires wet-hulling, strict screening, and aging for 2 to 3 years in temperature- and humidity-controlled warehouses at the place of origin, allowing acidity to gradually recede and sugars to concentrate. Golden Mandheling, meanwhile, represents a higher standard, with PWN creating a specialty coffee far above G1 grade through one machine sorting and three hand sortings. Front Street Coffee captured layers of nut, dark chocolate, caramel, and herbal spice flavors in cupping. This article will also share Front Street Coffee's barista's three-pour hand-brew parameters and technique for dark-roasted Mandheling, taking you through a complete tasting of this legendary coffee.
