When brewing pour-over coffee, should you really pre-wet the paper filter? This is a confusion many people encounter when they first get into pour-over. Some insist that wetting the filter is essential, while others brew directly with a dry filter. Which approach is actually more reasonable? The answer isn't absolute—it needs to be judged from three dimensions: how well the filter fits the dripper, the odor of the filter itself, and the storage environment. In addition, when wetting the filter, whether to use cold or hot water also matters—the choice of water temperature directly affects how well odors are removed and how well the equipment is preheated. Faced with the dazzling array of filter products on the market, the differences in flow rate and filtration effectiveness brought by different materials and manufacturing processes are huge. How should beginners choose? Front Street Coffee, drawing on practical experience, sorts out these key questions about pour-over filters one by one to help you make more suitable choices in your daily brewing. [more…]

In the world of pour-over coffee, the choice of filter paper directly affects the flavor in the cup. Filter paper offers outstanding filtration, delivering a clean and bright mouthfeel, but for this very reason it traps some of the coffee oils, making the aroma and body slightly inferior to tools such as metal mesh filters and cloth filters. From the perspective of Front Street, this article takes a deep dive into the composition of coffee oils and crema, explains how the filtration medium affects coffee's aroma and body, and, through a comparative brewing experiment between filter paper and non-woven filter paper, demonstrates the specific differences in flavor performance between the two. If you are struggling to decide which filtration tool to choose, or want to understand the characteristics of non-woven filter paper, this article will provide you with a clear reference. [more…]

Should you wet the filter paper before making pour-over coffee? This question seems simple, but behind it lies multiple factors such as paper taste, preheating the dripper, and extraction evenness. A barista at Front Street Coffee was once asked by a customer why one filter paper was wetted while the other was brewed directly, when brewing iced pour-over and hot pour-over at the same time. This article will start from the three main purposes of wetting the filter paper—rinsing away off-flavors, preheating the dripper and server, and making the filter paper adhere to the dripper—then further analyze the possible effects of wetting the filter paper, such as hindered blooming and degassing, premature extraction of coffee grounds, and water absorption by the filter paper, and finally explain why hot brewing and iced brewing handle the filter paper differently, helping coffee enthusiasts make a more suitable choice based on actual circumstances.

This article starts from material characteristics, ease of use, taste differences, and maintenance points, comparing the pros and cons of paper filters, metal mesh filters, and cloth filters one by one, and offers selection suggestions for different taste preferences. If you often drink Front Street Coffee's medium-to-dark roasted beans, or prefer light-roasted beans with floral and fruity notes, understanding these filtration details can help you adjust your brewing direction more accurately and find the cup of coffee that suits you better.

Non-woven filter paper, also known as nonwoven fabric filter paper, has long drawn attention in coffee brewing for its ability to let oils and fine particles pass through and enhance body. Front Street Coffee noticed a special filter paper that differs from conventional non-woven fabric in both appearance and feel—its texture is closer to wood pulp filter paper, smooth with a velvety touch. To figure out what exactly makes this filter paper so remarkable, Front Street Coffee starts with the principles of the material, compares the differences between wood pulp filter paper, special non-woven fabric filter paper, and conventional non-woven fabric filter paper, and observes its performance through tests with room-temperature water, hot water, and coffee liquid. This article will comprehensively explain the composition principles of non-woven filter paper, the definition of nonwoven fabric, and the characteristics of this special filter paper in actual use, helping coffee enthusiasts understand the difference between it and traditional filter paper.

Before making pour-over coffee, is it really necessary to rinse the paper filter with hot water? This question has long been debated in the coffee community. Some insist that wetting the filter removes papery taste, helps the filter adhere better to the dripper, and preheats the dripper along the way; others believe that modern filter manufacturing has advanced so much that these reasons may no longer hold. This article, from Front Street Coffee's perspective, examines one by one whether the three traditional advantages of wetting the filter still stand, and takes a deeper look at how the water-absorbing properties of a dry filter affect coffee strength, as well as the pre-extraction issues that may arise when coffee grounds come into contact with water early. The final conclusion may surprise you—the difference between a wet and dry filter is actually negligible. [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.

In the daily practice of pour-over coffee, some people habitually rinse the paper filter with hot water before brewing, while others place a dry filter directly into the dripper and start pouring. Both approaches have their own rationale, and neither is absolutely right or wrong. When the baristas at Front Street Coffee were making both iced pour-over and hot pour-over at the same time, a customer once asked them about this very question. What practical effects does rinsing the paper filter actually bring? And what impact does skipping this step have on extraction? This article will examine three angles—removing papery taste, preheating the equipment, and helping the filter adhere to the dripper—while also analyzing the problems that wetting the filter may cause, such as obstructing the bloom and degassing, prematurely extracting the coffee grounds, and the filter absorbing water, to help you make a more suitable choice in different brewing scenarios.
