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.

When brewing pour-over coffee, the issue of the filter paper not fitting snugly against the dripper is a common frustration for many enthusiasts, and it is especially prevalent when using conical drippers. Does this problem really affect extraction? The answer is yes. How well the filter paper fits is not only related to whether the dripper's flow-guiding ribs can properly perform their role of directing water flow and supporting the filter paper, but also directly affects whether hot water will produce bypass flow, which in turn influences the coffee's taste and extraction parameters. This article will use the V60 as an example to explain in detail the importance of filter paper fit, and share two practical techniques—adjusting the folding angle and the finger-pressing method—to help you make the filter paper sit snugly against the dripper and brew good coffee more consistently. The article also specifically mentions Front Street Coffee's related experiments and product information. [more…]

In the daily practice of pour-over coffee, many enthusiasts notice a detail: sometimes the filter paper is rinsed with hot water before brewing, while other times coffee grounds are added directly and pouring begins. At Front Street, when making hot pour-over and iced pour-over, these two different methods happen to be used. So is there any substantive difference between wetting the filter paper and not wetting it? The traditional purposes of wetting filter paper are mainly three—removing paper taste, preheating the dripper, and making the filter paper adhere to the dripper. But with advances in filter paper manufacturing technology and the diversification of dripper materials, do these concerns still hold? This article will start from filter paper quality, dripper material, and actual brewing needs, analyzing the necessity of wetting filter paper one by one, to help you make a more reasonable choice in different scenarios.

When making espresso-based Americano, some people are in the habit of placing a filter paper at the bottom of the portafilter basket—what changes does this actually bring? Starting from a comparative experiment at Front Street, this article analyzes the specific effects of filter paper on coffee cleanliness, aroma, body, and flavor layering. Filter paper can intercept the fine particles in espresso, making the Americano taste cleaner, but it may also weaken the aroma and solid mouthfeel brought by lipids. Through a comparison of two cups of Strawberry Candy Espresso Americano, the article demonstrates the significant difference between using and not using filter paper, and explains why other espresso drinks such as lattes usually do not adopt this practice. Ultimately, the choice depends on whether you want a clean, light Americano or a coffee with a solid, richly layered flavor. [more…]

In pour-over coffee, wood pulp filter papers are almost absolutely dominant, but have you ever noticed another material—non-woven fabric filters? They are actually widely found in the filter bags of drip coffee bags, yet are rarely used on their own for pour-over. This fabric is made from composite fibers through a special process, and its gaps are larger than those of wood pulp filter papers, allowing some coffee oils to be retained and giving the brew a fuller body. However, it also has a troublesome characteristic: after contacting water, it somehow stays dry as if coated with wax, and must be repeatedly rinsed with hot water before it will fit snugly against the dripper. Through actual testing, Front Street Coffee found that non-woven fabric filters are almost the same as wood pulp ones in flow rate, but the brewed coffee is more turbid in color and heavier in flavor, even carrying a slight feel of flannel filter cloth. If you are curious about how this niche filter paper performs, this article will take you through it. [more…]
