Many coffee enthusiasts, when making espresso, often overlook a step that seasoned baristas repeatedly emphasize—letting hot water run for a few seconds before extraction. This seemingly simple action actually has a significant impact on the final flavor of the coffee. This article will explain the necessity of pre-flushing from two perspectives: brew head cleanliness and extraction stability, and through a comparative experiment at Front Street, demonstrate the specific differences that flushing versus not flushing makes on espresso taste and extraction yield. At the same time, we will also analyze why coffee machines that have been unused for a long time tend to cause extraction deviations, helping you more precisely control the quality of every cup of espresso in your daily routine.

In pour-over coffee, the pouring method after blooming directly affects the final flavor. Is it the "one-pour" method, where all the water is poured at once, or is it divided into two or more stages? These two approaches differ significantly in extraction time, flushing efficiency, and controllability. Staged pouring extends the extraction window, making the release rhythm of sweet, sour, and bitter compounds more controllable, thereby enhancing the coffee's complexity. But more stages isn't necessarily better; in everyday brewing, two to three stages are most common, as they allow flexible adjustment and make it easier to hit the ideal extraction time. This article will compare in detail the differences between the one-pour method and staged pouring, and explain what kind of coffee beans are better suited to staged extraction. [more…]

When using an espresso machine to extract espresso, there is one action that veteran baristas repeatedly emphasize, yet it leaves many enthusiasts puzzled—that is, releasing a few seconds of hot water before locking in the portafilter. This seemingly simple step actually affects both the cleanliness of the group head and the stability of the extraction result. Through comparative experiments, Front Street Coffee found that espresso extracted with and without pre-flushing shows perceptible differences in acidity, concentration, and balance, and the extraction yield data confirms this as well. This article will analyze in detail the two core functions of pre-flushing, helping you produce a good espresso more consistently in your daily routine. [more…]

After the Luckin Yuzu C series returned, it quickly became popular, and many people on social platforms have hailed it as a "fat-flushing miracle," with claims even circulating that "one cup can make you lose two jin." However, actual test data show that although a single cup of the Yuzu C series contains about 105 to 150 calories, blood sugar rises fairly quickly after drinking it, and the blood sugar increase of Yuzu C Iced Tea can reach 5.1 half an hour after a meal. In addition, the formula contains high-fructose corn syrup and white granulated sugar, so so-called 0 fat does not equal low sugar. For people who need to lose fat or control blood sugar, this drink may not only fail to help with weight loss, but may instead promote fat synthesis and increase hunger due to a large secretion of insulin. This article, combining netizen reviews and formula information, restores the true picture of the Luckin Yuzu C series. [more…]

Besides refreshing the mind and waking you up, coffee can also promote intestinal peristalsis, which unexpectedly makes the restroom experience an important standard for judging whether a coffee shop is comfortable. Recently, a netizen from Shandong posted on social media, reviewing some of the coffee shops they had visited from the perspective of the restroom, with a unique angle and rich details. Cleanliness and hygiene, along with smooth flushing, are the basics, while spaciousness and ventilation, pleasant aromas, and the provision of disposable toilet seat covers, wet wipes, sanitary pads, and hand cream become bonus points. A layout with dry-wet separation and a reasonable flow also greatly increases favorability. At the same time, many coffee shops cannot provide restrooms due to space or plumbing limitations, or they impose restrictions on customers using the toilet. Those shops with complete facilities not only meet physiological needs, but also win repeat customers and reputation through detailed service. Front Street Coffee reminds us that paying attention to these often overlooked experiences may bring coffee shops an unexpected win-win effect. [more…]

Coffee, wine, and tea are all flavor foods, yet China's coffee bean production accounts for only about 1% of the global total, and most beans on the market are imported. If you just want to try brand-name beans with a sharing mindset, feel free to give them a try; but if you're giving them to someone who knows coffee, it's best to give up on shopping at large supermarkets. Whether espresso or single-origin, there is only one core principle when buying: fresh roasting. Beans from supermarkets or chain brands are often already months past their roast date, with their aroma severely lost—even nitrogen-flushing and other preservation techniques can't save them. In addition, if you can obtain information on variety, altitude, and processing method, and the more specific the origin, the more guaranteed the quality usually is. This article recommends several freshly roasted specialty coffee brands and explains why small bean merchants deserve more attention. [more…]

When the weather turns hot, iced coffee becomes the first choice for many people. Iced pour-over preserves the flavor layers of pour-over coffee while adding a refreshing chill, but making a good iced pour-over isn't as simple as adding ice cubes to hot pour-over. Melting ice dilutes the coffee's strength, and directly applying hot-brew parameters often results in a weak glass of iced coffee water. This article centers on the two cores of extraction yield and strength, and compiles four zero-threshold iced pour-over methods: the high-strength high-extraction method, the ice-rinsing method, the stirring method, and the ice-bath cooling method. Each method comes with specific parameters and operating steps using a medium-light roast Front Street Coffee Kafa Forest as an example, helping you easily make a full-flavored, sweet-and-sour balanced iced pour-over at home.
