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 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…]

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.

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.

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. [more…]

When brewing pour-over coffee, wetting the filter paper is a common step, but have you ever considered that the choice of water temperature can also change the final flavor? This article analyzes the different results brought by wetting the filter paper with hot water versus cold water from three dimensions: the state of the filter paper, extraction efficiency, and coffee temperature. 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…]

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, 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…]

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.

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…]
