Many friends who are just getting into pour-over coffee share a common misconception: they believe that the deeper and more even the coffee bed is, the better the coffee tastes. In reality, the shape of the coffee bed only reflects the pouring method and has no direct connection to coffee flavor. This article starts from a customer inquiry at Front Street's shop to explain why the coffee bed in specialty coffee is sometimes flat, and which factors truly determine coffee taste. It also shares three practical points: appropriately increasing the water flow, concentrating the hot water in the center, and choosing coffee beans that are not too high in density, helping you easily produce a symmetrical, deep coffee bed at home. The article also uses Front Street Yirgacheffe Gudingding, PWN Golden Mandheling, and others as examples to illustrate the differences in how various beans perform. [more…]

Many friends who are just getting into pour-over coffee are always fascinated by the puffy dome during blooming and the "deep pit" that forms in the coffee bed after brewing. It seems that only when these two phenomena appear can a cup be considered a proper pour-over. However, in practice, people often find that the deep pit isn't something you can create just by wanting to. Today, Front Street Coffee is here to talk about how the deep pit actually forms, and whether it can serve as a standard for judging whether coffee is good or bad. [more…]

Many friends who are just getting into pour-over coffee often hold an almost worshipful attitude toward the expansion of the coffee bed and the deep pit, believing that producing a deep pit signifies superior skill. Front Street found this phenomenon to be quite common when talking with customers in the shop, so we decided to analyze the conditions for the formation of the deep pit from a fundamental perspective. In fact, the deep pit is mainly related to three factors: the roast level of the coffee beans, the circular pouring pattern, and the dose of grounds, with roast level having the most significant influence. Dark-roasted beans have low density and expand noticeably, making it easy to form a thick wall of grounds and a deep pit, while light-roasted beans are the opposite. In addition, pouring in small circles preserves the wall of grounds around the edge, and a large dose of grounds also provides enough support for the deep pit. But an attractive coffee bed does not equal good-tasting coffee; the real point of observing the coffee bed is to check whether the pouring was even and whether the wall of grounds was damaged. This article will systematically sort out the brewing logic behind the coffee bed for coffee lovers, helping everyone return to the brewing parameters themselves. [more…]

Many enthusiasts, after finishing a brew, will see a uniform and deep bowl-shaped coffee bed left in the dripper, and wonder how this state is formed. Front Street Coffee also often encounters similar questions in daily brewing. In fact, the final shape of the coffee bed cannot directly determine whether a cup of coffee tastes good, but it does reflect some operational details during the brewing process. This article will explain how to brew a deep-pit coffee bed from three aspects: coffee bean density, pouring method, and pouring uniformity, and will also explain why light-roasted high-density beans often find it difficult to form a deep pit. If you also want to understand the principles behind the coffee bed, as well as brewing suggestions for beans such as Front Street Ethiopia·ALO and Front Street Yirgacheffe·Guddingding, please read on.

After pour-over brewing is finished, the coffee bed in the dripper often takes on different shapes—some people can produce a beautiful, even deep pit, while others end up with a flat bed or even a muddy crater. What exactly are these coffee bed shapes telling us? In fact, the appearance of the coffee bed mainly reflects information about the pouring method and the coffee grounds themselves, and has no direct correlation with whether the coffee tastes good. Front Street will start with six common coffee bed states, interpreting one by one the causes and meanings of the deep pit, the offset pit, the flat bed with a grounds wall, the flat bed without a grounds wall, the fractured bed, and the muddy pit, to help you better judge whether your pouring is appropriate in daily brewing and make timely adjustments.

If you were born before the millennium, your first impression of black coffee was probably a uniform bitterness—the only non-bitter coffee being Nescafé 2-in-1.

Recently, a café in Shunde, Guangzhou, placed deep-fried cicada sloughs on iced Americano, launching a special drink that has sparked heated discussion among netizens. Cicada sloughs, commonly known as golden cicadas, have a tradition of being eaten in some regions, and early summer is the peak season for catching them. The shop owner claims that pairing them with cold brew offers a unique flavor, but many netizens say the visual impact is too strong and hard to accept. At the same time, cicada sloughs, as a heterologous protein, carry an allergy risk, and parts such as the legs may also carry bacteria and parasites, so caution is needed when trying them. This article takes you through the story behind this explosive drink and the precautions to note. [more…]

Deep-roasted coffee beans should typically present a full, smooth, and rich mouthfeel, yet many enthusiasts find the flavor rather thin when brewing with pour-over methods. Front Street Coffee, drawing on common issues, points out that the problem often lies in the type of dripper, the coffee-to-water ratio, the extraction time, and the pouring technique. If you want to brew a heavy-bodied cup, it is recommended to choose a Kono dripper or a Kalita wedge-shaped dripper, which rely primarily on immersion extraction, keep the coffee-to-water ratio between 1:13 and 1:15, and maintain an extraction time of around 2 minutes; when pouring, use small circular motions and keep the water level from exceeding the coffee bed, which can also noticeably enhance the body. This article analyzes these key parameters one by one to help you achieve a more solid mouthfeel when brewing deep-roasted beans such as Blue Mountain and Mandheling. [more…]

In yesterday's article sharing flavor descriptions, the section on "body" sparked a big response among coffee lovers, and a friend asked via the backend: his deep-roasted coffee tastes rather thin—what methods can enhance the coffee's body?

Different roasting levels of coffee beans lead to completely different flavor profiles. Starting from the history of coffee, this article tells how Alfred Peet, a pioneer of dark roasting, used heavy roasting to change the face of American coffee, and how George Howell opened up another flavor path on the East Coast with a light roasting approach. The article systematically sorts out the differences between dark roasting and light roasting in color, weight loss ratio, and flavor performance, and points out that dark roasting brings sweetness and body, while light roasting highlights bright fruit acidity and regional character. Whichever one you prefer, as long as there are no negative flavors such as bitterness or saltiness, whether coffee is good or bad ultimately comes down to personal preference. Front Street Coffee recommends a variety of beans with different roasting levels for enthusiasts to choose according to their taste. [more…]

When brewing pour-over coffee at home, have you ever tasted the flavor of one bean in a cup of another? This is very likely the work of fine powder residue left inside the grinder. If a grinder is not cleaned for a long time, electrostatic fine powder and dark roast bean oils attached to the metal burrs will accumulate more and more, which not only affects the extraction flavor, but may also clog the passage and shorten the life of the equipment. This article, compiled by Front Street Coffee, systematically explains the maintenance and calibration methods for manual and electric coffee grinders, from simple daily cleaning, no-disassembly cleaning with cleaning tablets, to disassembly deep cleaning and burr wear inspection, helping you determine when a simple cleanup is enough and when deep maintenance is needed, so that every cup of coffee maintains a clean and accurate flavor performance.

Many pour-over enthusiasts habitually judge coffee quality by the shape of the coffee bed left in the dripper, believing that the deeper the bed, the better the taste. Is this belief correct? What can a deep bed actually tell us? In reality, the state of the coffee bed only reflects the uniformity of pouring and does not directly determine flavor. To produce an ideal coffee bed, uniform pouring alone is not enough—other conditions must also be met. This article will take a deep dive into the true relationship between the coffee bed and coffee taste, and share the complete set of factors that go into forming a perfect coffee bed. [more…]
