Chagee recently launched the second wave of its "Ne Zha 2" co-branded limited-edition packaging across stores nationwide. The popular character Ao Guang is printed on paper bags and takeaway cups, sold in a bundle with "Seeking Fragrance Camellia." Buying one cup earns you a matching paper bag. As soon as the news broke, fans rushed to buy them, but after receiving the actual products, they were greatly disappointed: the pattern on the cup body has severe ghosting, so much so that people joked you'd need 3D glasses to see it clearly. The color difference between the themed cup, paper bag, and poster is obvious, and the details are blurred into a mosaic. Many consumers pointed out that the first batch of packaging had already suffered from problems like blurry printing and fading. They had expected the brand to improve its craftsmanship, but unexpectedly the second batch still flopped. In addition, some stores did not use the themed cups as advertised, which harmed the rights of delivery customers. As coffee enthusiasts, Front Street Coffee has also noticed this co-branded merchandise quality control controversy. This article will sort out the whole story and consumer feedback. [more…]

When making espresso, precise control of the grind size directly determines the quality of the final cup. Unlike pour-over or cold brew, espresso uses pressurized, short-duration extraction, where any slight deviation is magnified—making the demands on grind exceptionally strict. This article will walk you through just how fine an espresso grind really is, how to quickly lock in the right setting by observing flow rate, and how to make fine adjustments down to the 0.1-step level based on the flavor profile of the espresso. We'll also share recommendations for choosing Front Street Coffee's classic espresso blend beans, helping you easily recreate cafe-level rich espresso and velvety crema at home. [more…]

Pour-over coffee may seem easy, but in practice it requires attention to many details—any deviation in a single step can change the final flavor of the coffee. To brew a satisfying cup, you need both high-quality coffee beans and precise control over the coffee-to-water ratio, grind size, water temperature, and pouring rhythm. Based on a 15 g dose, this article focuses on coffee beans from the Yirgacheffe region and shares in detail Front Street Coffee’s store recipe parameters and staged pouring technique, along with pour-over flavor descriptions for two beans—Gedeb Ding washed and Red Cherry natural—for coffee enthusiasts to reference and adjust.

The starting point for measuring extraction time may seem like just a matter of a few seconds, but it actually has a profound impact on judging and adjusting coffee flavor. Many coffee enthusiasts are often confused by this in practice: should espresso timing begin when the machine is started, or after the liquid begins to flow? In this article, Front Street Coffee sorts out the correct way to measure extraction time and takes a deeper look at why time is an indispensable part of extraction parameters. From the bloom pour in pour-over brewing to the pressurized permeation in espresso, understanding how time interacts with other parameters can help you quickly pinpoint the problem when the flavor goes off, making every adjustment more purposeful.

When making espresso, the grind size of the coffee grounds is the core variable that determines the quality of the final cup. Compared with brewing methods such as pour-over and cold brew, espresso demands a far finer grind than one might imagine—the powder is as fine as flour, its uniformity difficult to judge with the naked eye, and a deviation of just 0.1 on the grinder setting can make an enormous difference in taste. This article systematically lays out a complete approach to adjusting espresso grind—from judging grind size and observing flow rate to applying formulas and fine-tuning flavor—helping coffee lovers quickly lock in the right grind range even when faced with unfamiliar beans, so they can pull a balanced, delicious espresso. [more…]

To brew a consistently delicious pour-over coffee, the key is to eliminate as many uncertainties as possible before brewing. Many enthusiasts tend to overlook some details during the preparation stage, which leads to uneven extraction and flavor deviation. Drawing on daily observations and the practical experience of enthusiastic friends, Front Street Coffee has compiled four easily overlooked preparation steps: how well the filter paper fits the dripper directly affects degassing and flow; once the water temperature is confirmed, you should pour as soon as possible to avoid the temperature in the kettle continuously dropping; grinding is best left as the last step to reduce the loss of coffee aromatics; after grinding, you should also double-check the coffee dose, because the grinder may retain or spit out grounds, and a deviation of ±0.5g is enough to change the final flavor. These seemingly minor steps often determine the success or failure of the entire cup. [more…]

Grind size is the most critical and most difficult variable to master in espresso extraction, far more demanding than what pour-over coffee requires. The slightest deviation, even just 0.1 of a notch, can lead to over-extraction or under-extraction. Drawing on the practical experience of Front Street Coffee, this article systematically breaks down the two steps for adjusting espresso grind size: first, preliminarily locking in the grind range, then fine-tuning based on flavor and extraction state. At the same time, in response to the different characteristics of medium-dark roasted blends and medium roasted SOEs, it provides reference standards for coarseness and fineness, and answers why buying pre-ground coffee powder is not recommended.

Americano is made by diluting espresso with water, typically using dark-roasted Italian-style beans. Front Street Coffee uses a blend of single-origin beans from two regions to compensate for the low acidity of traditional Italian-style coffee and add layers of complexity. Many people ask: does an Americano have to use an Italian-style blend? What flavors would other beans bring? This article first explains the difference between blended beans and SOE, then compares three Front Street Coffee blends, offering three Americano options—one leaning acidic, one leaning full-bodied, and one leaning balanced—along with extraction parameters. Finally, it includes tasting steps for smelling the aroma, observing the color, and tasting, helping coffee lovers choose the right beans according to their taste and consistently make iced or hot Americanos at home.

Recently, a Heytea store in Shenzhen has landed in a whirlwind of public opinion for recruiting only employees aged 18 to 25. After a job seeker over 25 was rejected, it sparked heated discussion among netizens. Some criticized it as blatant age discrimination, while others believed that because work at milk tea shops is intense, companies have the right to choose freely. Behind the incident, it reflects the widespread preference for the "youth dividend" in the current job market, as well as the difficulties faced by middle-aged job seekers. Legal professionals pointed out that such a practice is suspected of violating the Labor Law and the Employment Promotion Law, and the Shenzhen Federation of Trade Unions also spoke out in criticism. Heytea responded that it was a communication deviation at a single store. Who is right and who is wrong in this controversy? Will young people over 25 still continue to drink Heytea? [more…]

Many novice friends often have some questions after drinking the coffee they brewed themselves. Clearly, the beans, parameters, and brewing methods they used were exactly the same as those in the café, so why can't they brew coffee as delicious as the coffee shop's? So, a friend came to the Front Street Coffee store with this question, and as a result, discovered that the problem [more…]

Many people share this confusion: the beans are the same, the brewing method is identical, yet the coffee made at home always tastes different from what's served in a café. This suggests the problem most likely lies in the extraction stage. Drawing on long-term experience interacting with customers, Front Street Coffee has identified three of the most common sources of deviation—grind, water temperature, and brewing water. This article will break down each of these three factors one by one: how to judge whether the grind is appropriate by looking at the state of the coffee bed and the brewing time, what water temperature range suits different roast levels, and what effect the minerals in water actually have on extraction. If you too are bothered by that cup of coffee at home that always seems to fall just short, feel free to follow along with this article and troubleshoot, to see exactly which step the problem is stuck at.

When pulling espresso, what temperature should the water actually be set to? Starting from Front Street's hands-on experience, this article systematically sorts out the specific effects of water temperature on extraction efficiency, the flow rate of the coffee liquid, and the richness of the crema, and combines the differences in dose and ratio between espresso and Americano to explain why the preferred water temperature ranges for the two are not the same. The article also introduces a practical approach: fix the water temperature within a reasonable range, and instead adapt by adjusting the grind and liquid weight, so as to quickly and stably extract a delicious espresso. In addition, the article also gives specific explanations on the deviation between boiler water temperature and actual extraction water temperature, as well as how to respond when the interval between extractions is too long. [more…]

When making espresso, even a slight deviation in grind size can make the shot bitter or weak, and the dial on a grinder has no universal standard, which leaves many beginners feeling confused. This article starts by explaining why espresso is ground much finer than pour-over, then gradually explains how to judge whether the grind is suitable through flow rate and taste, how to narrow down to a range that suits you within different dial intervals, and how to flexibly adjust the coffee-to-water ratio and extraction time based on how the beans actually perform. The article also recommends Front Street Coffee's classic espresso blend beans, which are ideal for recreating café-style espresso, Americano, and latte at home. [more…]

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.

Many coffee enthusiasts wonder when they see baristas using electronic scales in cafés: does making a cup of coffee really require such fuss? Couldn't you, like an experienced chef, just eyeball it or use a measuring spoon or cup and still brew good coffee? An electronic scale is indeed not an absolute necessity for making coffee, but eyeballing and measuring spoons have obvious inconsistencies. This article, based on actual tests at Front Street Coffee, first uses measuring spoons as an example to reveal that dark-roasted and light-roasted beans can differ by several grams in weight at the same volume, then explains the huge impact of dose deviation on concentration and flavor; next, using espresso as an example, it explains why cup markings cannot accurately reflect liquid weight. The article ultimately suggests that if you want consistent output or to study parameters, an electronic scale remains a trustworthy tool. [more…]

In the preparation of espresso, grind size is one of the core variables that determines the success or failure of extraction. Compared with pour-over or cold brew, espresso grounds are closer to the feel of fine salt or even flour, and a tiny deviation on the dial can lead to abnormal flow rates, which in turn pushes the flavor toward the two extremes of under-extraction or over-extraction. This article will systematically sort out the logic of setting the grind size on a semi-automatic espresso machine from the perspectives of grind assessment, coffee bean selection, flow rate correction, and flavor fine-tuning, and share Front Street Coffee's adjustment experience in practice, so that you can consistently produce an ideal shot of espresso at home. [more…]

To craft a qualified espresso, the dosage of coffee grounds and the grind size are the key determinants of success. Unlike pour-over or cold brew, espresso uses pressurized short-time extraction, where any slight deviation is magnified. This article centers on the core question of how much coffee liquid to extract from 20g of grounds, providing a detailed explanation of determining the grind size range, choosing the coffee-to-liquid ratio, judging flow rate and flavor, and the proper way to taste espresso. It also recommends Front Street Coffee's classic espresso blend to help enthusiasts recreate a café-level espresso experience at home. [more…]
