We all know that green coffee beans cannot be directly ground, extracted, or drunk. They need to undergo one more round of processing—roasting—before they can be brewed and tasted. Roasting is an endothermic process for coffee beans. Before roasting, many flavor compounds in green coffee beans cannot be brought out; whether smelled or tasted, they are just a faint grassy note.

Front Street Coffee recently came across a uniquely shaped pour-over filter paper—the dual-chamber filter from Spain's Sibarist. Because its interior is divided in two by a partition, netizens have jokingly dubbed it the "double-flavor hot pot filter." The original design intent was to let coffee beans with different characteristics each be extracted separately in a single brew, but at 37.44 euros for 30 sheets—about 9.4 yuan per sheet—it really is staggering as a disposable consumable. Front Street Coffee decided to make a DIY alternative, using two 01-size filter papers in a 02 conical dripper to replicate the dual-chamber structure, and to explore the water temperature and other parameters that need to be considered when actually brewing with this kind of filter. This article will walk you through the dual-chamber filter's construction principle, its official pricing, how to make a DIY alternative, and the core considerations for using it, so you can see whether it's worth buying.

The usual way to make a pour-over blend is to mix different beans together and then grind and brew them as one, but a dual-chamber filter paper launched by Spanish accessory maker Sibarist breaks that convention. The filter has a paper wall down the middle that splits the original bed of grounds into two, letting baristas brew two different coffees at the same time, or the same bean at two different grind sizes, and ultimately fuse a brand-new flavor in a single cup. After the product appeared at the SCA Expo in Chicago, its price was announced: a pack of 30 sheets costs 30.94 euros, or about 8 yuan per sheet, which had plenty of enthusiasts saying they could not bring themselves to pay it. Chinese netizens, meanwhile, saw in its unfolded shape a resemblance to a double-flavor hot pot, and their imaginations ran to a "mandarin duck latte"玩法 in which coffee grounds go on one side, tea leaves on the other, and hot milk is poured through to brew it.

Many people wonder why some teas have the characters "single bush" in their names—like the common Phoenix Dancong, aged Phoenix Dancong, and frozen Wudong Dancong. To understand this naming convention, we need to start with the definition of Phoenix Dancong: it is made by selecting superior individual bushes from the Phoenix Shuixian population, which are then cultivated, picked, processed, and sold separately. These tea trees, processed using the single-bush method, are collectively called Phoenix Dancong. In contrast is the blending process used for Pu'er tea: to create different flavors, tea makers blend leaves from different mountains, seasons, and tenderness levels. Of course, some Pu'er enthusiasts prefer single-bush ancient tree tea. It is precisely for the convenience of cultivation and management, picking and processing, and consumer purchasing that Phoenix tea farmers classify and name tea trees based on tree morphology, finished tea characteristics, and growing environment. Accumulated over generations, this has formed hundreds of strains and varieties. This article will explain the issues everyone cares about regarding Wudong Dancong: its tin box packaging, market price, shelf life, and storage time. [more…]
