When pulling espresso, you sometimes remove the portafilter and find a large amount of hot water left in the basket, with the puck wet, even loose and misshapen. This phenomenon not only affects consistency in the cup but also makes it hard to identify the root cause. Starting from the principles of espresso extraction and pressure release, this article systematically breaks down the three common causes of water pooling in the basket: grinding too fine, which impedes the flow of hot water through the coffee bed; using too small a dose, which leaves too much distance between the puck and the shower screen; and insufficient pressure on home machines, which weakens the back-suction effect. It also offers Front Street Coffee's adjustment suggestions to help coffee enthusiasts quickly pinpoint the problem and improve extraction flow rate and puck condition. [more…]

Many coffee enthusiasts have found during brewing that simply adding a little more coffee grounds causes a noticeable decline in the resulting flavor. The reason behind this often lies in the amount of grounds exceeding the reasonable capacity of the current dripper, while the brewing technique has not been adjusted accordingly. This article will focus on the suitable grounds amounts for the two common dripper models, 01 and 02, analyzing the specific effects of too much or too little coffee on extraction uniformity, flow rate, and the final flavor. At the same time, for scenarios where you only have a small dripper on hand but need to brew a large amount of coffee, it provides a complete solution including coarsening the grind size, slightly adjusting the water temperature, and pouring techniques, and offers practical reference suggestions based on Front Street Coffee's standard parameters.

Many espresso enthusiasts have encountered this situation: after extraction, you remove the portafilter and find the puck wet and soft, unable to hold its shape, with a pool of water still sitting at the bottom of the basket. This is clearly not an ideal extraction state. Is the problem with the basket or the dispersion screen, or do the extraction parameters need adjustment? This article will analyze the possible causes of water accumulation one by one from the perspectives of grind size, coffee bean freshness, dose matching, group head cleanliness, and machine pressure, and provide corresponding solutions. The article will also share Front Street Coffee's dose control experience from daily dialing-in to help you find the root of the problem and return espresso extraction to a dry, intact puck state.

After pulling an espresso shot, standing water left in the portafilter basket and a wet, mushy puck that won't hold its shape are problems many coffee enthusiasts run into. This article systematically sorts out several common causes of water pooling in the basket: too small a dose, a grind that is too coarse or too fine, and unstable pressure delivery from the espresso machine. The article points out that standing water is essentially a reflection of the extraction parameters and the machine's condition, and does not necessarily mean the coffee will taste bad; what truly affects flavor is the parameter error itself. Front Street suggests that if the flavor is off, you should first adjust the dose or the grind parameters to correct the coffee's taste, rather than simply fixating on the standing water. [more…]

It might be used for making specialty coffee drinks, or perhaps you just want a light taste of coffee to get a hint of the flavor~ Occasionally, some friends have the idea of "brewing just a small cup of coffee with only a small amount of coffee beans." But if you've actually tried it, Front Street believes it shouldn't be hard to notice: compared to brewing with a large dose of coffee grounds, brewing a good cup with a small dose [more…]

Want to make a decent espresso at home? The coffee-to-water ratio is one of the most critical parameters. This article draws on the hands-on experience of Front Street Coffee, first explaining why espresso mostly uses blend beans rather than single-origin beans, then explaining how the dose is limited by the basket capacity, why a 1:2 coffee-to-liquid ratio is regarded as the golden ratio, and how too much or too little coffee grounds affects flow rate and flavor. It then introduces, one by one, the four espresso blend beans currently offered by Front Street—Sunflower Warm Sun, Specialty Blend, Commercial Blend, and Dark Cocoa Blend—including their recipe proportions, flavor descriptions, and target drinkers. Finally, it supplements the ways to taste espresso, helping you understand why it emphasizes mouthfeel, aroma, and finish rather than distinguishing temperature changes like pour-over. [more…]

Extracting a shot of espresso can be done in as little as twenty-odd seconds, but it is precisely this difference of just a few seconds that is enough to push the flavor in the cup in a completely different direction. As one of the core variables in the extraction process, time never exists in isolation—any change to dose, brew ratio, or grind size will affect the final extraction result. This article will start from the reasonable range for extraction time, break down one by one how dose and grind size affect flow rate and flavor, and share Front Street's practical approach to daily dialing in at the shop, along with several espresso blend beans suitable for practice, to help coffee lovers find a stable and delicious espresso recipe more quickly.

Front Street Coffee shops always stock over thirty varieties of pour-over beans, so it's inevitable that there will be leftover coffee beans that don't get used up. Simply throwing them away is truly a waste, so Front Street Coffee chooses different handling methods based on the amount of remaining grounds: when the amount is around 10g, it can be brewed directly, but the parameters need to be adjusted or a smaller-dose dripper used; if it's less than 6g, it can be topped up by blending with other beans; the coffee beans can also be made into desserts like lemon zest slices, or turned into decorative items such as aromatic bracelets. This article explains in detail the principles and key operational points of each approach, helping you make the most of every single coffee bean. [more…]

In the practice of pour-over coffee, the coffee dose is one of the key variables determining the extraction result. Many coffee enthusiasts run into this problem: at the end of a bag of beans there are always a few grams left, too little for a single cup on its own, yet too wasteful to throw away. Based on Front Street Coffee's hands-on testing experience, this article systematically explores the differences between brewing with a small dose of around 7 grams and a conventional 15-gram dose, analyzes the extraction challenges caused by a thinner coffee bed and faster water flow, and offers two sets of adjustment plans for different levels of water-control skill—one that relies on a finer grind combined with a thin stream and three-pour approach, and another that uses a heavy stream and staged raising of the water level to lower the barrier to execution. Whether you are a complete beginner or a pour-over player with some experience, you can find a small-dose strategy that suits you. [more…]

When using a bottomless portafilter to extract espresso, you may occasionally encounter a situation where the coffee liquid does not fall vertically but instead sprays out from the filter basket. This phenomenon is known in the coffee community as channeling. Although it does not necessarily make the coffee taste bad, it significantly increases the probability of uneven extraction, making it more likely to produce a cup that is both sharply sour and bitter. In this article, Front Street Coffee systematically sorts out the formation principles of channeling and summarizes five operational steps that easily trigger channeling: uneven distribution of coffee grounds, uneven tamping pressure, knocking or bumping when locking the portafilter into place, too little coffee dose or too coarse a grind, and too many clumps of coffee powder. For each situation, Front Street Coffee also provides specific improvement suggestions to help everyone reduce the probability of channeling occurring in daily extraction. [more…]

Blooming is a key step in pour-over coffee that affects extraction stability. By releasing carbon dioxide trapped in the coffee grounds, it creates the conditions for the smooth release of flavor compounds later on. But blooming is not absolutely necessary—the "one-pour" method previously shared by Front Street Coffee can skip this step entirely. So how exactly should you control the water amount, timing, and technique during blooming? Using 2x the coffee dose and 30 seconds as standard references, this article analyzes one by one the specific changes in coffee flavor when the water amount is too little or too much, and when the time is too short or too long, and offers pouring suggestions suitable for beginners to help you make more accurate judgments in actual practice.
