Many pour-over beginners don't run into clogging issues while brewing, yet after finishing, the coffee bed ends up perfectly flat, with no indentation at all. This shows that water flow control during extraction wasn't up to par, so a bowl-shaped bed couldn't form, which very easily leads to uneven extraction. Front Street has summarized three common mistakes: the bed wasn't lifted high enough, the water flow lacked enough stirring force, and the pouring circles were too wide in amplitude. We'll go through the causes one by one and give adjustment methods for each. Also, the depth of the coffee bed has no necessary connection to the roast level—whether you can produce a bed depression depends on your pouring technique, not how the beans were roasted, while the depth of the depression is determined by the dose of coffee.

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…]

When browsing brands like Front Street Coffee or coffee teaching courses, you will often see single-origin beans recommended for brewing with 15g of coffee grounds. This number seems to have become the golden standard for pour-over coffee, but why exactly 15g? What problems would 10g or 20g bring? Starting from Front Street Coffee's teaching practice, this article deeply analyzes the impact of coffee dose on coffee bed depth, water flow state, and extraction results, explaining why 15g can become the most suitable single-serving parameter for the 01 dripper. At the same time, many enthusiasts are also curious about the difference between the 01 and 02 drippers. We will provide an answer from the perspective of coffee bed depth and extraction uniformity, helping you understand the logic behind the parameters and brew more stable and delicious pour-over coffee.

In the world of pour-over coffee, the shape of the coffee bed is often overlooked, yet it profoundly influences the final flavor expression. Starting from cases previously shared by Front Street Coffee, this article systematically sorts out the specific effects of coffee bed thickness and shape on extraction efficiency, stability, and coffee taste. You will learn why the same beans present completely different layers or balance in different drippers, and also understand why every dripper has a recommended dose. Through a comparative brewing example of Front Street Coffee Ethiopia Huakui, we will intuitively see the flavor differences brought by conical drippers and flat-bottom drippers, helping you understand more thoroughly the logic behind dripper selection, so you can brew a good cup of coffee more confidently.

In the bloom phase of pour-over coffee, after water is added, the coffee bed should absorb water and expand, forming a plump "hamburger" dome. But sometimes we find the coffee bed utterly motionless, with no sign of expansion at all—what exactly lies behind this? This article will systematically sort through the various factors that cause a bloom that fails to swell, analyzing everything from the freshness of the coffee beans and storage methods to grind size and roast level. It will also explain the possible effects of an overly long bloom time and offer Front Street Coffee's grinding calibration recommendations for actual practice, helping you pinpoint the root of the problem and improve the consistency and flavor performance of every cup of pour-over.

After brewing is complete, the state of the coffee bed can reveal a lot about the extraction, and the color of the coffee liquid is also often used as a basis for judgment. Many people, upon seeing darker-colored coffee, instinctively assume it tastes stronger, or even suspect it is murky. In fact, the depth of color is related to extraction yield and roast level, but it does not directly equate to a higher or lower level of clarity. This article starts with the color of the coffee liquid, analyzes whether dark color indicates murkiness, and, using Front Street Coffee's comparative brewing examples, explains how to judge clarity through taste rather than sight, while also offering practical advice on bean selection, resting beans, parameter control, and pouring technique.

During the bloom phase of pour-over coffee, whether the coffee bed puffs up into a large dome or stays relatively flat actually hides quite a bit of information. Although the degree of doming can't directly tell us whether the coffee tastes good, it can reflect the freshness of the coffee beans, the roast level, and the extraction efficiency during brewing. This time, Front Street Coffee will help everyone understand: why do some beans puff up like a balloon during the bloom while others stay flat and collapsed? What role does carbon dioxide play in this? Why do dark roasts and fresh beans puff up more? How do extraction parameters influence the degree of doming? Once you understand these things, you can read the bloom dome as a "bean status file" rather than mistakenly treating it as a standard for judging flavor quality. [more…]

The natural process is the oldest method of coffee processing, allowing the fruit to dry naturally while the beans mature inside the pulp, resulting in intense flavor and prominent sweetness. Today, the natural process has been refined, from African raised beds to single-layer slow fermentation, greatly improving quality and even becoming the top choice for competition-grade coffee. This article will guide you through a comprehensive understanding of the natural process's operational flow, flavor advantages, traditional flaws, and modern improved techniques, and recommend freshly roasted beans such as Front Street Natural Huakui and Front Street Red Cherry, allowing you to understand the unique charm of naturally processed coffee from theory to practice.

In the world of pour-over coffee, the agitation method is a more aggressive extraction technique than water-stream agitation. It acts directly on the coffee bed through a tool, accelerating the release of soluble flavor compounds. Front Street Coffee shared this method last year, but did not elaborate on the specific steps. This article will systematically sort out the three major application scenarios of the agitation method—the blooming stage, remedial action when extraction efficiency is insufficient, and its use when actively adjusting parameters—and provide an in-depth analysis of the key details to note when using agitation, such as grind size, agitation force, and number of agitations, helping coffee enthusiasts master this technique more precisely.

In the third wave of specialty coffee, pour-over coffee has become the top choice for many enthusiasts thanks to its clean cup profile and its ability to showcase origin flavors. As the core piece of equipment, the dripper's shape design directly affects the extraction path—conical drippers represented by the Hario V60 emphasize layers and fruit acidity, while the flat-bottom dripper pioneered by the Kalita Wave focuses on balance and sweetness. Front Street Coffee commonly uses the V60 in its daily production. This article will systematically compare the extraction logic of the two drippers from the perspectives of pouring uniformity, coffee bed depth, rib structure, and drain hole design, and will include three-pour brewing parameters for the flat-bottom dripper to help you find a clearer direction in equipment selection and technique adjustment.

Many coffee enthusiasts share this confusion: they can consistently brew delicious coffee with a size 01 small dripper, but when they switch to a size 02 large dripper, the results are always disappointing. This is not a regression in skill, but rather an essential difference in structure and usage logic between large and small drippers. The 01 dripper corresponds to 1–2 servings, while the 02 dripper corresponds to 3–4 servings. The difference is not just capacity—the drainage hole, bed depth, and flow rate all change with size. Front Street Coffee's brewing tutorials use the 01 dripper as the standard, but if the same technique is applied directly to the 02 dripper, over-extraction easily occurs due to excessively long extraction time. This article will analyze the core differences between the two drippers in depth and provide adjustment plans for the larger dripper, helping you brew satisfying coffee even with the 02 dripper.

To consistently brew a good cup of coffee, you can't get around the basic parameters of dose, grind size, water temperature, and coffee-to-water ratio. Once these are set reasonably, the remaining variable mainly comes down to pouring technique. This article focuses on these core steps, explaining the interplay between bed depth, extraction yield, and strength, and provides a three-pour approach suitable for beginners. It then uses the 2025 new-crop Natural Hualkui as an example to walk through a practical routine of 15 g coffee, 1:15, 91°C, and an 80% passing rate, while clarifying the concepts of Hualkui and Geisha that are often confused. The article also includes Front Street Coffee-related product and article recommendations. [more…]

The Yirgacheffe Kebel Aricha processing station brings together the hard work of about 650 to 700 smallholder farmers in the surrounding area, who hand-pick ripe cherries in exchange for cash payments. After strict sorting, the fruit is spread on raised drying beds to undergo four to six weeks of sun exposure, and during the first few days it must be turned at regular intervals to prevent over-fermentation. This batch of natural Aricha was rated G1, the highest grade, by the ECX, with outstanding performance in green bean appearance, consistency, freshness, and dry and wet aroma. If you prefer bright acidity and intense berry notes, this bean is not to be missed. This article also introduces Project Origin, a green bean sourcing initiative launched by Sasa Sestic. The program works directly with farmers in impoverished producing regions, pays purchasing fees 20% higher than the Fair Trade price, and is dedicated to strengthening the connection between roasters and coffee farmers. Front Street Coffee also recommends this excellent work with rich layers of flavor. [more…]

In the Guji region of Ethiopia, there is a place called Hambela that is quietly changing people's perception of natural coffee. Here, a processing method known as SLD—Single Layer Drying slow fermentation—is used, spreading coffee cherries in a single layer on raised beds and subjecting them to about 18 days of precise drying, so that every cherry receives the most even airflow and the fullest fermentation. Although this technique takes up more space and time, it gives the beans fuller sweetness and greater storage potential. Compared with traditional Yirgacheffe, Hambela coffee is gentler in acidity, yet superior in sweetness and body. This article will take you deeper into what makes this processing method unique and how it influences the final flavor of the coffee. Front Street Coffee also particularly recommends paying attention to beans from this region and experiencing their appealing expression, as warm and smooth as fruit tea. [more…]

Among pour-over coffee equipment, cone-shaped drippers and flat-bottom drippers are two completely different choices. The cake dripper gets its name because its filter paper resembles baking paper, and its flat bottom brings extraction characteristics opposite to those of the V60: the coffee bed is thinner and more uniform in depth, pouring does not require deliberately controlling the range, and even beginners can easily brew a balanced and full-bodied cup of coffee. Of course, the relatively slow flow rate also requires us to make targeted adjustments in our parameters. In this article, Front Street will analyze the structural principles and flavor tendencies of the cake dripper, and share a specific method for brewing Ethiopian Hamashu with the Origami dripper, including coffee dose, water temperature, grind size, and staged pouring technique, to give you a comprehensive understanding of the advantages and disadvantages of flat-bottom drippers.
