Can coffee bean blending happen in a single pour-over?

Coffee bean blending for pour-over usually means mixing beans, then grinding and brewing them together. A dual-chamber filter from Spanish accessory maker Sibarist breaks that habit: a paper wall splits the coffee bed in two, so two coffees, or one bean at two grind sizes, brew side by side and merge into one cup.

The filter debuted at the SCA Expo in Chicago, then went on sale at 30.94 euros for 30 sheets, roughly 8 yuan each, which drew complaints about price. Co-founder Joaquim Morató told Daily Coffee News the two chambers are controlled separately so each side has different contact time, yielding two extracts that converge in the server.

Pour-over coffee blending usually involves mixing different beans together, then grinding and brewing them as one, but a dual-chamber filter paper launched by Spanish accessory maker Sibarist breaks with this convention. The filter has a paper wall in the middle, splitting the original coffee bed space in two, allowing baristas to simultaneously brew two different coffees, or the same bean at different grind sizes, ultimately fusing a brand-new flavor in a single cup. After the product debuted at the SCA Expo in Chicago, its price was announced: a pack of 30 sheets costs €30.94, which works out to about 8 yuan per sheet, prompting many enthusiasts to say they simply can't bring themselves to pay that. Domestic netizens, meanwhile, likened its unfolded shape to a dual-flavor hot pot, and even came up with the idea of putting coffee grounds on one side, tea leaves on the other, and brewing with hot milk for a "mandarin duck" latte.

When it comes to blending in pour-over coffee, the process most people picture is probably this: first mix two or more kinds of beans together, then grind them together, and brew them together.

But recently, Spanish coffee accessory maker Sibarist has brought pour-over enthusiasts a completely different approach to blending. They launched a dual-chamber filter paper, with which baristas can simultaneously extract two different coffees, ultimately producing a pot of coffee that fuses the flavors of both beans.

The appearance of this dual-chamber filter paper is basically the same as a Hario v60 filter, except that when unfolded, there is a paper wall in the center, dividing the single space originally used to hold coffee grounds into left and right halves.

According to the designer, the "dual-chamber" structure is meant to give pour-over enthusiasts richer choices and variables—you can brew two different coffees at once, or use two different techniques to handle the same coffee.

In an interview with Daily Coffee News, Sibarist co-founder Joaquim Morató mentioned that the original design intent of the dual-chamber filter paper was to let the two independent spaces each be controlled separately, so that the contact time between the coffee grounds and water on each side would differ, thereby extracting two different coffee liquids that finally converge in the same cup.

Not only that, the two sides of the dual-chamber filter paper can hold coffee beans of different varieties, different ratios, and different grind sizes, and during brewing the barista can also handle the coffee beds on each side differently.

Morató gave a specific example: a barista can put 14 grams of medium-fine ground coffee on one side of the filter, aiming for as full-bodied a mouthfeel as possible; on the other side, use 5 grams of coarsely ground coffee, with the aim of strengthening the coffee's initial flavors, preserving the early stages of extraction, and adding an extra bright acidity to the blended coffee liquid.

In other words, if two different coffees are placed on the two sides of the dual-chamber filter paper, you get a cup of blended coffee; if the same bean is placed on both sides but at different grind sizes, then through the barista's brewing, it may be possible to amplify a certain flavor of that bean.

After this filter paper made its first public appearance at the SCA Expo in Chicago, its price was also announced: a pack of 30 filter papers sells for €30.94 (about 242 yuan), which works out to 8 yuan per filter paper—a price that really makes many people hesitate.

So some enthusiasts followed this idea and taped two v60 filter papers together to brew. Although it wasn't the original product, the result after trying it was quite unexpected—"two coffees with different characters and flavors fused together, producing a very good cup of coffee."

When domestic netizens saw how the filter paper looked when unfolded, they immediately thought of the dual-flavor hot pot on the dining table, so they gave it a down-to-earth name: "dual-flavor hot pot filter paper." And everyone's imagination ran wild, thinking that the real way to use this filter paper might be: put ground coffee on one side, a little tea on the other, and brew with heated milk—that way you'd get a true "mandarin duck" latte!
