Front Street Coffee's pour-over tutorials have long been based on a single-serving standard of 15g of coffee and a 200ml cup, but many enthusiasts are no longer satisfied with brewing just one cup and have begun trying to make two or three cups at once. Once the dose is doubled to 30g, the small 01 dripper can no longer handle it, and a V60 02 large dripper must be used instead. Increasing the dose is far from simply adding more coffee and water; a thicker coffee bed slows the flow rate, and as the extraction time lengthens, bitterness follows. Using the Sidra coffee beans as an example, Front Street Coffee starts with two variables—grind size and pouring stream—to make fine adjustments, compressing the total time from 2 minutes 53 seconds to 2 minutes 30 seconds so that the 30g brew comes close in flavor to a single-cup brew. This article fully records the parameter differences before and after the adjustment and the reasoning behind them, and also answers the question of whether the 01 dripper can be used to brew a large dose when no 02 dripper is available.

When brewing coffee, the grind size directly determines the surface area where water meets the coffee and the speed at which hot water passes through, and even a slight deviation can ruin the entire cup's flavor. If a moment of carelessness leaves the beans ground too coarse, how can you salvage the situation? This article compiles several practical remedies—from re-grinding to flexible adjustments of water temperature and time—and, using Guji Huakui 8.0 as an example, provides complete parameters and steps to still brew a clean, full-bodied cup even after the grind has come out coarse. Whether you use a hand grinder or rely on pre-ground coffee from a vendor, you can find a corresponding adjustment plan to bring each cup as close to ideal as possible. [more…]

Iced pour-over is not simply pouring hot coffee over ice; rather, it is an extraction method in which ice rapidly cools and moderately dilutes the coffee liquid, also known as "flash-chilled pour-over." To make a cup that is both refreshingly cold and rich in aromatic layers, you need to readjust parameters such as coffee dose, water volume, ice amount, grind size, water temperature, and timing. This article focuses on ice usage and application, the coffee-to-ice-to-water ratio, grind size adjustments, and two operational approaches—small-stream分段 and the stirring method—to help coffee enthusiasts make a balanced iced pour-over at home. It also provides specific references based on Front Street Coffee's commonly used parameters. [more…]

Can you still drink coffee beans that have been sitting for a long time? Why does the flavor deteriorate? This article centers on coffee bean freshness: first, it explains the causes of staleness and reference points for the optimal flavor period, and combines Front Street's verification to give storage recommendations; then it emphasizes safety—generally, roasted beans have a shelf life of about 1 year, and being past that date does not mean they cannot be drunk, but the flavor needs to be compensated for through the brewing plan. The focus is on adjustment ideas for brewing stale beans, including coarser grinding, longer pouring during blooming, and controlled circling, explaining why blooming is still crucial. Finally, it provides three environmentally friendly ways to reuse expired coffee beans: odor removal, cleaning, and plant fertilizer, helping you minimize the loss without wasting anything. [more…]

Ever brewed the same coffee beans at home, only to find it never tastes as rich as what you get in a café? The problem usually lies in strength or extraction yield. Insufficient strength often comes from using too much water and diluting the coffee, while under-extraction stems from poorly tuned parameters like water temperature, grind size, and brew time. This article breaks down in detail how to improve the flavor by adjusting the coffee-to-water ratio, water temperature, and grind size, and shares two sets of brewing parameters from Front Street for medium-light and medium-dark roasted coffee beans, helping you easily brew pour-over coffee with full aroma and standout flavor.

The choice of coffee dose for pour-over seems simple, but in reality it involves multiple coordination factors: the dripper model, the number of drinkers, and the pouring rhythm. Front Street Coffee's daily demonstration uses 15g of coffee as the baseline, but in actual brewing, doses that are multiples of 6 such as 12g, 18g, and 24g, doses that are multiples of 5 such as 15g, 20g, and 25g, and even 16g each have their own adherents. Behind different doses lie different reasoning logics—some start from the volume of brewed coffee, some compromise based on the dripper's recommended value, and others aim for easier calculations during pulse pouring. This article will focus on three typical doses—15g, 20g, and 30g—explaining the brewing approaches suited to each, and providing adjustment suggestions for dose, water amount, and dripper selection in a four-person pour-over scenario, helping you achieve consistent results even when sharing with multiple people.

When drinking coffee, a numb tongue and dry mouth—this rough tactile sensation is astringency. Astringency is not a taste but a tactile feedback caused by friction between the coffee liquid and the oral cavity. Its root lies in the excessive release of polyphenolic compounds in coffee beans—especially chlorogenic acid—which bind with salivary proteins and weaken lubrication. Astringency often interweaves with acidity and bitterness, forming sour-astringent or bitter-astringent notes. This article will begin with the causes of astringency, explain its relationship with extraction state, analyze which astringency counts as a quality characteristic, as well as the astringency that green beans themselves may bring, and offer specific ideas for improvement by adjusting extraction efficiency.

The most direct way to adjust the strength of pour-over coffee is through the coffee-to-water ratio. If you want a bolder cup, reduce the amount of water poured; if you prefer something lighter and more refreshing, simply increase the water. However, changing the coffee-to-water ratio doesn't just affect concentration—it also shifts the extraction yield. Within the parameters recommended by Front Street Coffee, 1:15 to 1:16 works for most coffee beans: 1:15 gives a solid body and full flavor, while 1:16 is lighter and more layered. If you're brewing a dark roast and want it stronger, jumping straight to 1:13 may lead to under-extraction and a missing finish—this is where grind size and water temperature come in to help. This article will systematically sort through various approaches to adjusting concentration, including coffee-to-water ratio, grind coarseness, water temperature changes, and the By Pass technique, to help you find the balance point across different roast levels.

Pour-over coffee and espresso are the two most mainstream brewing methods today, and most coffee beans on the market are developed around these two uses. The two have completely different extraction principles: pour-over is atmospheric-pressure drip filtration, similar to brewing tea, and produces a crisp, refreshing cup; espresso uses high pressure for rapid extraction, yielding a small, highly concentrated shot. Beyond differences in equipment and parameters, the roast level and blending approach of the coffee beans used also differ. This article will systematically sort out the differences between pour-over and Americano, from extraction principles, operational key points, and parameter adjustments to specific serving methods, and answer which is stronger and which is sweeter, while also sharing Front Street Coffee's practical experience in bean selection and making Americanos.

When the weather turns cold, many coffee enthusiasts notice that even with the same beans and the same technique, the coffee they brew comes out weak and lacking in flavor. This is not a problem with the bean roasting, but rather the low-temperature environment changes the rate at which the hot water loses heat, which in turn affects extraction efficiency. Starting from the principle of heat loss, this article explains in detail how cooling leads to under-extraction, and offers four actionable improvements: preheating the kettle spout, raising the water temperature, increasing the water volume, and lowering the pouring height. Finally, it includes Front Street Coffee's store information to help you consistently produce a delicious pour-over even in the cold season. [more…]

There is a dripper made entirely from a single steel wire, minimalist in function—it only holds the filter paper up and barely interferes with the flow of water. It is stretchable and compressible, lightweight and portable after collapsing, and affordably priced, but it tilts to one side when placed on a server. When brewing coffee with it, how does the flavor differ from that of regular drippers like the V60? Front Street conducted a comparative brew using Colombia·Frontera Geisha: 15g of coffee, a 1:15 coffee-to-water ratio, 92°C water, Ek43 setting 10, and a three-pour method. The total time was 2 minutes 50 seconds, the flow rate was noticeably slow, and the taste was bitter with some muddiness and a thin body. The problem is not the dripper itself, but that the parameters and technique need to be re-matched. [more…]

The V60#01 dripper is typically suited for 1 to 2 servings, with 15 to 20 grams of coffee being its optimal working range. But in reality, when drinking alone and not wanting too much, people reduce the dose, and when sharing with friends, they increase it. So, when brewing different doses in the same dripper, do the parameters really need to be changed? Front Street Coffee conducted three sets of comparative experiments using Ethiopian Yirgacheffe natural Red Cherry, with doses of 10 grams, 15 grams, and 25 grams, a fixed water temperature of 90°C, a 1:15 coffee-to-water ratio, medium-fine grind (80% passing through a Chinese standard No. 20 sieve), and circular pouring. The results showed that with a smaller dose, the flavor tends to be thin, while with too large a dose, bitterness may appear and the liquid level may awkwardly approach the rim of the cup. This article will break down the three brewing recipes one by one, their flavor performance, and the adjustment approaches for 10 grams and 25 grams, to help you find a more reasonable extraction method in this small dripper.

Many coffee enthusiasts habitually use safe powder-to-water ratios like 1:15 or 1:16 in their daily pour-over brewing. Front Street also often recommends such parameters to beginners. However, once a fixed brewing pattern of fixed coffee dose with fixed water volume is established, even if the dose differs by only one or two grams, the pouring water volume is often locked in by inertia, causing the actual powder-to-water ratio to quietly shift. The powder-to-water ratio directly relates to extraction yield and concentration, and these two in turn determine the flavor and mouthfeel of the coffee. This article uses a clever cup immersion extraction experiment, brewing 14g, 15g, and 16g of Front Street Yirgacheffe Red Cherry with the same 225ml hot water, measuring concentration and tasting flavor differences, to illustrate the importance of adjusting water volume in sync when fine-tuning the coffee dose, and to remind that when the dose difference exceeds 5g, grinding, brewing technique, and dripper also need to be adjusted in [more…]
