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.

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.

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.

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.

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%.
