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.

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.

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…]

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.

When brewing pour-over coffee, should the paper filter really be pre-wetted? This question seems minor, yet it can affect the final liquid volume, concentration, and flavor expression. This time, Front Street Coffee used two drippers, the V60 and Origami, along with two types of filters, conical and cake, to conduct comparative brews with wetted and non-wetted filters, comparing the differences one by one from liquid weight and refractometer data to actual tasting. At the same time, the article also explains in depth why the blooming stage should use twice the amount of water as the coffee grounds, and why the portion of liquid that first contacts the coffee grounds has a lower concentration. If you have also agonized over this detail, you may as well follow the experimental data and see it clearly. [more…]

Should you wet the filter paper with hot water or room-temperature water before pour-over coffee? Does this seemingly insignificant step really affect the final flavor? Many coffee enthusiasts share this confusion. In this experiment, Front Street Coffee used filter holders made of three different materials—resin, ceramic, and copper—and wet the filter paper with either room-temperature water or hot water above 90°C, conducting a comparative experiment under identical brewing parameters. The results showed that wetting the filter paper at different water temperatures does indeed lead to differences in the temperature and concentration of the coffee liquid, and the flavor profile also showed different tendencies toward sweetness and acidity. Through detailed experimental data, this article will analyze the mechanism by which the water temperature used to wet the filter paper affects the extraction process, helping you find the cup that best suits your taste.

Pour-over coffee enthusiasts often encounter a confusion: why do different baristas fold their filter papers in different ways? Which filter paper should be chosen, how should it be folded, and should it be pre-wetted? These seemingly minor details actually directly affect the flavor performance of the final cup. Front Street Coffee has accumulated considerable experience with filter paper usage in daily production, so this time we will conduct a systematic review centered on filter paper selection, folding techniques, and wetting treatment. Starting from the differences between natural wood filter paper and bleached filter paper, and then moving on to specific operational details, we hope to help everyone truly understand this seemingly simple step of filter paper, making every cup of pour-over more stable and clean.

In pour-over coffee, whether the filter paper needs to be pre-wetted has always been a matter of two approaches. Not wetting the filter paper can prevent the coffee grounds from contacting the paper too early and affecting extraction, while wetting the filter paper can wash away the papery off-flavors and dust. But for the V60 dripper with its large guide ribs, how well the filter paper fits is especially critical—Front Street Coffee's experiments show that poor fit noticeably slows the flow rate and brings negative flavors. Based on an analysis of the importance of fit, this article shares a simple and easy method that, using only finger pressure and the force of the water stream, can make the filter paper in a conical dripper fit at a rate as high as 95%.

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…]

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…]

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…]

When brewing pour-over coffee, how well the paper filter fits the dripper directly affects the extraction. Many enthusiasts use a pressing technique yet still find that the filter won't sit flush, and the root cause often lies in the folding step. After customers reported this issue at their stores, Front Street Coffee put together a detailed demonstration of the correct way to fold a cone-shaped paper filter. From folding along the seam and pressing the crease to the technique for securing it once it's in the dripper, every step matters. This article reproduces the entire process, explains how to handle specialty filters such as non-woven ones, and shows how to make the filter sit snugly for iced pour-over without wetting it first—so you can brew a consistent, great-tasting cup at home.

The paper filter for pour-over coffee may look simple, but it actually hides quite a few details. Many coffee enthusiasts have encountered the situation during brewing where one side of the paper filter lifts up after being rinsed with water and cannot fit snugly against the dripper. Although it will not ruin the entire cup of coffee, it does affect the extraction. This article focuses on the folding and fitting issues of conical paper filters, starting with the selection of the dripper and filter paper, and then gradually breaks down the key steps such as folding, creasing, handling the conical bottom, and securing the filter with water, helping you get this detail right in your daily pour-over brewing. Front Street Coffee will also share, based on its own experience, why the resin version of the V60 dripper has more advantages in terms of standardization. [more…]

When brewing pour-over coffee, many people habitually rinse the paper filter with water first, aiming to make the filter cling tightly to the dripper. But does whether the filter clings or not really sway the taste of a cup of coffee? Front Street used a V60 and Yirgacheffe Red Cherry to run a set of comparison experiments, dividing filter states into four types: fully clinging, folded edge sticking up, placed crookedly, and not clinging at all, and recorded extraction time and flavor differences for each. The results showed that although the degree of clinging does not change the overall direction, it does leave traces on sweetness, acidity, mouthfeel, and astringency. Below, we break down the reasons one by one in the context of the brewing process. [more…]

In the extraction process of pour-over coffee, how well the filter paper fits the dripper directly affects the final cup quality. Many enthusiasts find that if the filter paper does not sit tightly against the dripper wall, even the best dripper cannot deliver its intended design advantages. Take the currently popular V60 dripper as an example: its unique spiral rib structure can hardly function when the filter paper fails to fit properly. Therefore, before formal brewing, the step of wetting the filter paper is especially critical—it not only removes the papery taste and dust from the filter paper itself, but is also the core operation for making the filter paper fit tightly against the inner wall of the dripper. Starting from the structural function of the dripper, this article will explain in detail the key points of folding and fitting the filter paper, and share Front Street Coffee's experience in actual operation, to help everyone improve the stability and flavor performance of pour-over extraction.

Wetting the filter paper before brewing coffee is almost a standard step for all pour-over enthusiasts, with the usual goals of making the filter paper fit snugly, removing paper dust, and, if hot water is used, warming the cup along the way. However, most tutorials rarely discuss in depth how much the degree of fit between the filter paper and the dripper actually affects the final taste. Front Street conducted two sets of controlled experiments, using V60 and KONO drippers respectively, paired with filter papers in different states of fit for brewing, and tasted and compared them one by one. The experiment used the floral-fruity Front Street · Gedin Gedin and the nutty-sweet Front Street · Brazil Red Bourbon, and the results showed that a poorly fitting filter paper significantly changes the flow rate, which in turn affects the extraction yield and concentration, producing noticeable differences in mouthfeel. [more…]
