When extracting espresso, the normal flow rate should start slow and gradually speed up, but sometimes the exact opposite occurs—after pressing the extraction button, the coffee liquid bursts out violently, then quickly thins and slows down. This abnormal flow rate—fast first, then slow—often indicates a problem with the extraction yield, and the resulting espresso's flavor is less than ideal. From Front Street's perspective, this article systematically breaks down the four major factors behind this phenomenon: the dose exceeding the basket's standard gram weight, uneven tamping causing channeling, the pressure pump set too high leading to an overly aggressive extraction, and the coffee beans having finished degassing and no longer being fresh. For each cause, the article provides specific adjustment solutions to help coffee enthusiasts find the root of the problem and correct it. [more…]

Recently, an iced Americano method called "flash extraction" has become quite popular in the coffee community. It bears some resemblance to the all-ice Americano, also using only ice cubes and espresso, but the amount of espresso poured in is much larger—almost equivalent to the total liquid volume of a regular hot Americano. Put simply, this method involves rapidly extracting a large amount of espresso all at once, essentially yielding a "long shot" espresso—a Lungo. The difference is that this shot does not come with an excessively high extraction rate, and contains fewer bitter compounds, so when made into an Americano, it has low bitterness and a pronounced sweetness. For those who don't have an espresso grinder, or whose grinder can't grind fine enough, this method is especially friendly—you just need to appropriately increase the water amount to compensate for the lack of extraction efficiency caused by coarser grinding and insufficient puck resistance. Below, Front Street Coffee will discuss the specific parameter ratios and recommend a few medium-light roast beans suitable for this method. [more…]

When making espresso at home, have you ever run into the problem of a fast flow and a weak, watery taste? Even if you follow a 1:2 coffee-to-water ratio, the result still lacks the rich, full-bodied mouthfeel of a coffee shop. The root cause is often an improper grind size, which leads to insufficient extraction efficiency. Starting from the underlying logic, this article will teach you how to quickly judge and adjust the grind size using just two core parameters—a 1:2 coffee-to-water ratio and a 30-second extraction time—so you can consistently extract a rich, intense espresso suitable for milk drinks. It will also discuss how roast level affects flavor and recommend high-sweetness, full-bodied espresso beans such as Front Street Coffee's signature blend, helping you easily master the art of dialing in your grinder.

Recently, a so-called "Mixue Bingcheng weight-loss method" has become popular on social platforms. The routine involves drinking grape iced Americano, jasmine green tea, and iced fresh lemonade in sequence within one day, while trying not to eat anything else. Some followers claim they can lose three to four jin the next day. This method is essentially similar to a liquid fast, relying on water loss and a reduction in intestinal contents rather than actual fat loss. Many who tried it reported discomfort such as weak hands and feet, palpitations, headaches, and insomnia, and doctors also warn that using it rashly may trigger hypoglycemia, hair loss, and even abnormal liver and kidney function. Both Mixue Bingcheng stores and customer service said that these three drinks have no weight-loss effect. [more…]

In the practice of pour-over coffee, flow rate and circling rhythm are two variables that are easily overlooked yet profoundly affect the final flavor. Front Street Coffee has previously conducted dedicated tests on these two factors separately. This time, we further cross-combined flow rate and circling speed, using two extreme methods—slow circling with a small stream and fast circling with a large stream—to conduct a comparative brewing of a fruity, rich Front Street Colombia Sidra. The experiment was carried out under completely identical conditions of dose, coffee-to-water ratio, grind size, and water temperature. Through concentration measurement and flavor description, it reveals the specific effects of different pouring strategies on extraction efficiency and taste direction. Whether you prefer a full-bodied, rich cup or a light, delicate one, this article will provide reusable adjustment ideas for your daily brewing. [more…]

Ice drip coffee and iced pour-over coffee are often mentioned together, but the two differ significantly in extraction principles, flavor expression, and brewing process. Ice drip is a low-temperature slow extraction, while iced pour-over is a high-temperature fast extraction followed by cooling. Temperature greatly affects the breakdown rate of oils, acids, and sugars in coffee, thereby shaping distinctly different aromas, mouthfeels, and layers. From the perspective of Front Street Coffee, this article systematically sorts out the respective characteristics of high-temperature extraction and low-temperature extraction, and, using Honduras Sherry coffee beans as an example, records in detail the brewing parameters and flavor comparison of ice drip and iced pour-over, helping coffee enthusiasts more clearly understand the essential differences between the two kinds of iced coffee.

When brewing pour-over coffee, the size of the water stream and the speed of the circling often determine the direction of the final flavor. This article analyzes these two variables: how a small stream and a large stream respectively change the thickness of the coffee bed, the drainage speed, and the mouthfeel; and how the speed of circling affects the washing force and extraction efficiency. Using 15g of coffee, a 1:15 coffee-to-water ratio, and a water temperature of 91℃, it conducts a comparative brew of two combinations—"small stream with slow circling" and "large stream with fast circling"—recording the differences in concentration and flavor to help you understand the true role of circling in extraction and adjust your grind and technique accordingly.

To make a decent espresso at home, you need to get three things straight: how much coffee you use, how much liquid you extract, and how fine you grind. The standard reference is a 1:2 coffee-to-liquid ratio—about 9 grams of coffee yielding 18 grams of liquid for a single shot, and 18 grams of coffee yielding 36 grams for a double, with the actual output fine-tuned to taste. As for grind size, watch the flow rate: if it runs fast, grind finer; if it runs slow, grind coarser, until the extraction time falls within the right range. The roast level of the beans also matters a lot—medium-dark roasts and darker make it easier to achieve a balanced flavor. Drawing on the real-world parameters of Front Street Coffee's classic blend, this article lays out the extraction logic clearly in one go. [more…]

Got an espresso grinder and espresso machine, but always stuck at the espresso dialing-in step? Either it sprays everywhere or nothing comes out, either it's too sour or too bitter. The problem often lies in the grind size. Espresso is a pressurized fast extraction, releasing a large amount of aromatic compounds within twenty to thirty seconds, so any subtle change gets amplified. Relying on the grinder setting alone is far from enough—you also need to judge based on the extraction state. This article, drawing on Front Street Coffee's daily production experience, explains how to quickly find the right grind range for a bag of beans through extraction time, brew ratio, and flavor performance, and provides fine-tuning directions and practical advice. [more…]

Want to make a balanced espresso at home but keep struggling with unstable flow rate and flavors that swing between sour and bitter? The truth is, there is no one-size-fits-all fixed parameter set for espresso extraction—coffee bean condition, grinder performance, machine pressure, and water temperature can all skew the results. This article approaches the topic from six dimensions—dose, brew ratio, extraction time, flow rate, pressure, and water temperature—and systematically explains how to customize a suitable extraction plan for the blend you have on hand, with specific references based on Front Street Coffee's classic blend and Strawberry Candy Espresso. It also includes methods for measuring espresso concentration and extraction yield to help you use golden cup data as a guide for adjustments, so you can ultimately find the cup you truly enjoy. [more…]

To make a decent espresso at home, the coffee-to-water ratio and grind size are two core variables you can't avoid. Standard espresso is usually based on 1:2, with a single shot using about 9 grams of coffee to extract 18 grams of liquid, and a double shot using 18 grams of coffee to 36 grams of liquid, but the actual output still needs fine-tuning based on how it tastes that day. The most intuitive way to judge whether the grind size is right is the extraction flow rate: if the liquid comes out too fast, the grind is too coarse and needs to be made finer; if the liquid comes out too slow, the grind is too fine and needs to be made coarser, until the extraction time falls within a reasonable range. Besides the parameters, the choice of beans is equally key—medium-dark roast blends or darker are more likely to achieve a balanced, stable flavor. This article will organize an actionable set of adjustment ideas around dose, ratio, grind size, and extraction time. [more…]

On an espresso menu, espresso is an irreplaceable foundation; whether it's a latte or an Americano, everything is built upon it.
