What Exactly Is Double-Chamber Filter Paper? The High-Priced Yin-Yang Pot Filter Paper Pour-Over Method and Budget Alternatives

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.

Double-chamber filter paper overturns pour-over blending logic: a new way to brew two coffee beans in one pot and the price controversy

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.
