Whether you are just starting out or want to refine your technique, you can find practical reference solutions here. [more…]

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.

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…]

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…]

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.

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…]

At the same time, drawing on Front Street Coffee's brewing experience, it offers recommendations for filter holders made of different materials such as ceramic and resin, and explores the actual impact of preheating the sharing pot on the temperature of the brewed coffee. Whether you are pursuing sweetness or delicate flavors, you can find a way of wetting the filter paper that suits you. [more…]

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 discussions about pour-over coffee equipment, the dripper often takes center stage, while the filter paper—which performs the critical filtration task—tends to be overlooked. In fact, although filter paper accounts for only a small portion of the cost, it directly affects how coffee flavors are presented—common issues such as "fit" and "papery taste" are inseparable from it. When faced with the three mainstream shapes on the market—cone, fan, and cake—along with options like 01/02 sizes, natural and bleached, and different brands' paper textures, how should one make the right choice? Drawing on Front Street Coffee's practical experience, this article systematically sorts through filter paper styles and shapes, model sizes, bleaching processes, and paper texture differences, helping coffee enthusiasts find the one that better matches their own dripper and brewing preferences.
