In the world of pour-over coffee, paper filters may be the mainstream choice, but flannel cloth filters, with their unique material properties, still hold their own in many specialty coffee shops today.

This characteristic makes it especially suitable for brewing dark-roasted coffee beans. This article will walk you through the historical origins of flannel cloth filters, their brewing performance, usage techniques, and the correct methods for daily cleaning and maintenance. Front Street Coffee will also share relevant product information to help you gain a comprehensive understanding of this traditional yet charming filtration device. [more…]

Speaking of flannel filter cloth, many friends may have only seen it in some Japanese films and TV dramas or in Japanese-style brewing introduced by bloggers, and have never actually used it.

Flannel cloth brewing has always held a unique charm in the coffee world, capable of producing a rich body and sweetness that filter paper struggles to match. This time, Front Street Coffee will use a flannel cloth to brew a pot of Front Street Blue Mountain, and along the way discuss the characteristics and operational details of this brewing method. Flannel has larger pores than filter paper, allowing it to retain some of the coffee oils, making the mouthfeel smoother and fuller—especially suited to deep-roasted beans with robust flavors. However, this technique places demands on pouring speed, water temperature, and skill; a slight misstep can affect the flavor. The following sections will systematically introduce the background knowledge of flannel cloth brewing, the steps for use, the brewing parameters for pairing with Front Street Blue Mountain, and the principles behind flow rate changes, helping enthusiasts master this classic brewing method.

In the world of coffee brewing, the choice of filtration medium often determines the flavor direction in the cup. From Turkish coffee, which was mainly boiled before the 19th century, to the filter paper and dripper invented by Mrs. Melitta, to the artisanal use of flannel cloth in Japan, each filtration method carries a different extraction logic. Today, the filter paper, flannel cloth, and metal mesh commonly used in pour-over coffee each have their strengths and weaknesses: filter paper brings a clean and transparent mouthfeel, flannel retains oils and fine particles, achieving a rich and mellow flavor, while metal mesh poses new challenges in terms of pore size and extraction method. Front Street Coffee uses Ethiopian Santa Vini beans for comparative brewing, and by adjusting the pouring technique, reveals the causes of under-extraction with metal mesh and directions for improvement, providing a practical brewing reference for coffee enthusiasts.

The flannel filter cloth retains coffee oils, making the mouthfeel richer and smoother, and is especially suited to the full-flavored Front Street Blue Mountain coffee. But what grind size should be used when brewing with a cloth filter? Is it the same as the common grind size for the KONO dripper? Front Street Coffee conducted a comparative experiment using three grind sizes—BG-5R, BG-6M, and BG-6A—with 20 grams of coffee, a water temperature of 85°C, a coffee-to-water ratio of 1:13, and a single-pour brewing method. The results showed that BG-5R was somewhat strong with a slight astringency, BG-6M had a somewhat thin mouthfeel, while BG-6A performed in a balanced and mellow way. The article also explains the reasons behind the changes in flow rate of the flannel filter cloth and offers grind size recommendations for dark-roasted beans. [more…]

The siphon coffee maker, also known as the syphon, originated in Germany. It relies on heating the lower chamber to create pressure that pushes hot water up to the upper chamber to complete extraction. It is very popular in Japan and has gradually become popular in China. Its shape resembles chemical apparatus, often appearing in nostalgic films and TV shows, and it carries a mysterious aura. From the professional perspective of Front Street, this article systematically sorts out the upper chamber, lower chamber, and stand structure of the siphon, analyzes the pressure-difference extraction principle, introduces three heat sources—alcohol lamp, gas burner, and halogen lamp—as well as the trade-offs between flannel filter cloth and round filter paper. Then, taking Front Street Brazil Queen Estate beans roasted in-house as an example, it provides parameters such as a water temperature of 88°C, 18 grams of coffee powder, and a 1:10 coffee-to-water ratio, along with a six-step operating process, and explains filter cloth cleaning and storage as well as suitable coffee bean types.

Can pour-over coffee have oils? The answer is yes, but it requires a different approach. The crema of espresso is essentially oil encapsulating carbon dioxide, and it is the lipids in the coffee beans themselves that truly give coffee its rich body and aromatic boost. Because pour-over uses a filter paper with excessively strong filtration, it is nearly impossible to retain oils. To change this, you simply need to switch to a device with slightly weaker filtration performance, such as a flannel cloth or non-woven filter paper, and Front Street has clear recommendations on this. This article will explain the mechanism by which lipids work and compare in detail the pros and cons of different filters and the key adjustment points, to help you achieve a richer mouthfeel in pour-over.
