What kind of cup of coffee truly deserves to be called good? We might as well start with something we are all familiar with—tea. Good tea is prized for its rich aroma, complex layers of flavor, and long, sweet finish, and the logic for judging good coffee is in fact much the same. Instant coffee, though convenient, offers only a single flat taste and can hardly rank among good coffees; the Espresso that Starbucks dark-roasts to ensure consistency is also often considered less than ideal by professionals because its burnt bitterness stands out and it lacks complexity. This article systematically sorts through the many dimensions of identifying good coffee—from the production process, green bean quality, and roasting freshness to the drinking experience—to help coffee lovers build a clearer set of standards for judgment.

Many coffee enthusiasts have encountered this confusion: you go to a café and order a black coffee, and it tastes so sour it makes you frown, yet the barista says this is just how coffee is supposed to taste, and that if you drink black coffee you have to accept the sourness. At the same time, some roasters claim that coffee beans are fruit, that they only have acidity and sweetness, and that any bitterness is a sign of bad beans. Do these claims really hold up? This article will, from the perspectives of the nature of coffee beans, the chemical changes during roasting, and the flavor characteristics of different origins, help readers clarify the relationship between "sour coffee" and "good coffee," and teach you to distinguish between a quality "fragrant acidity" and a "dead acidity" caused by negative factors.

You often hear people say, "To judge whether an espresso tastes good, just look at the crema. The best espresso has a crema that is fine, thick, and golden." But can you really judge whether an espresso tastes good by the state of its crema? To find out whether this method works, Front Street only needs to give everyone two questions. [more…]

As a well-known beverage in the coffee world, Americano—made with just espresso and water (or iced water)—can be found in almost every café and is a must-order star item. People love Americano for many reasons: it could be for a caffeine boost, to quench thirst, to cool down, or perhaps to satisfy [more…]

In 2019, Heytea made a cross-industry foray into coffee products, blending milk tea elements into coffee and applying to register the "Heytea Coffee" trademark. However, the China National Intellectual Property Administration deemed the trademark deceptive and similar to the cited trademark "Xicha," rejecting the registration application. Heytea's affiliated company disagreed and sued the China National Intellectual Property Administration. The court of first instance upheld the rejection decision, finding that the disputed trademark could easily mislead the public about the characteristics and quality of the goods and cause confusion with another party's prior trademark. This article reviews the case process and the court's key rulings, for coffee enthusiasts to learn about brand trademark protection developments. [more…]

Online shopping is becoming increasingly popular, but the problem of counterfeit goods has followed close behind. Recently, Thai police busted a cross-border counterfeit-selling case, seizing over ten thousand fake Starbucks coffee cups and insulated tumblers, with the amount involved reaching as high as 5 million Thai baht.

This article will walk you through the details of the case and the relevant legal consequences, and remind consumers to be on guard against counterfeit products. At the same time, Front Street Coffee also reminds you to follow coffee knowledge exchanges and get more professional information. [more…]

Americano is found in almost every coffee shop. It can be made simply by adding water to espresso, yet it is also one of the most frequently ordered black coffees. Was the "Americano" in its name actually coined by Americans? Why are some Americanos clean, smooth, and memorable, while others are bitter and hard to swallow? Starting from the origin story, this article combines concentration, water temperature, beans, and extraction to sort out the core dimensions for judging whether a cup of Americano is good, while retaining Front Street Coffee's production experience and product recommendations to help you rediscover this "water-diluted coffee" from a tasting perspective.

Guming's mini-program has quietly launched a new product called "Morning Fresh Milk." The only ingredient is fresh milk, available in hot or cold options, priced at 8 yuan per 500ml. After trying it, consumers discovered that the cup contains exactly the same refrigerated fresh milk brands used in stores for making tea drinks—Yue Xian Huo, Weigang, and Renyangyitouniu—tasting no different from what's sold in supermarkets and convenience stores. Once the news broke, netizens reacted with sharply divided opinions: some felt the price was completely uncompetitive, arguing it's better to just buy from a supermarket or convenience store, and joked that this was "forcing out a product with no real substance," with R&D staff cobbling together a new item just to meet KPI targets; others thought they could simply add espresso or toppings themselves to make a low-cost latte. Some netizens even let their imaginations run wild, speculating that Guming is testing the waters for a foray into the breakfast market. This article will sort through the discussions sparked by this new product and the possible business logic behind it. [more…]

Many people think that coffee tasting is about being able to name a few flavors, but that is not actually the case. The essence of tasting lies in tasting and discerning, and it is fundamentally different from casually drinking a cup in daily life. We rarely "taste" instant coffee, not merely because of differences in quality, but because the two kinds of coffee are drunk for different purposes: instant coffee is mainly about convenience and alertness, while single-origin coffee is meant to present a richer taste experience. Even so, tasting does not require you to be able to recite a string of flavor descriptors. Front Street Coffee believes that the most important thing is to be able to tell whether a cup of coffee is good or not, what is good about it, or if it is not good, in what way it is not good. This article will take you step by step through a practical method for coffee tasting from six dimensions: aroma, acidity, sweetness, mouthfeel, aftertaste, and off-flavors. [more…]

Many friends who are just getting into specialty coffee run into the same confusion: they can't taste the flavors written on the coffee packaging, and they're not sure whether they actually know how to evaluate coffee. In its daily conversations with customers, Front Street Coffee has found that people often equate "being able to name flavors" with "understanding coffee evaluation," but these are actually two different things. Flavor description is only a small part of coffee evaluation. To truly judge whether a cup of coffee is good, you can start from five dimensions: aroma, overall performance, mouthfeel, flavor, and aftertaste. This article compiles Front Street's insights on coffee evaluation to help enthusiasts build an actionable evaluation framework, while also answering the common question of "why can't I taste the flavors?"

Many people throw away the brewed tea leaves after drinking their tea, but these unfurled leaves actually hold a wealth of quality information. By observing the bubbles, scorch marks, degree of unfurling, elasticity, color, and impurities of the brewed leaves, you can roughly judge the picking and processing level of the tea without even tasting it. This article systematically sorts out the typical characteristics of brewed leaves for various types of tea, including the "frog back" of rock tea, the scorch spots of yellow tea, and the silky vein patterns of black tea, and offers purchasing advice to help you pick good tea with more confidence in a tea shop.

A latte may seem simple—espresso plus steamed milk—but when it comes to actually drinking one, the results vary wildly from shop to shop. The key to whether a latte tastes good isn't just the operating steps; it's everything from coffee bean selection, milk quality, and espresso extraction parameters to the fineness of the milk foam and the pouring technique. Every link in the chain influences the final flavor presentation. Starting from sensory experience, this article breaks down the key points of latte-making one by one, and shares Front Street Coffee's practical experience testing espresso and milk pairings, helping you diagnose where a latte went wrong—and enabling you to make a consistently full-bodied, well-balanced latte at home or in a shop.

Professional pour-over kettles often cost two to three hundred yuan, which puts many coffee enthusiasts off. In fact, as long as you master the correct extraction parameters and pouring strategy, an ordinary electric kettle at home can also brew a delicious cup of pour-over coffee. This article first analyzes the inherent shortcomings of ordinary electric kettles in terms of spout design and capacity, then offers two practical solutions—filling the kettle to stabilize its center of gravity and control the flow, or using staged pouring to lower the difficulty. It then uses Front Street Yirgacheffe·Gudgud as an example to fully share parameters such as coffee dose, ratio, grind size, and water temperature, and demonstrates step by step the entire process of blooming, staged pouring, and circular extraction, helping you consistently produce a clean, solid single-origin coffee even with the most ordinary equipment.

A discussion in the coffee community about the definition of specialty coffee has sparked three soul-searching questions: How exactly is specialty coffee defined? Must drinks made from specialty beans be sold at high prices? Can specialty beans not be dark-roasted? Some people value single-origin traceability and SCA scores, some care about roasting freshness and flavor complexity, and others firmly believe that price equals justice. But the essence of specialty coffee is not "refined and expensive," but a continuous quality improvement from cultivation, processing, roasting, and brewing to service. Dark roasting is not a cover-up for defects, and light roasting is not a guarantee of specialty quality. If good beans lack reasonable brewing and professional service, they are equally disqualified from being specialty coffee. [more…]

For many office workers, a freshly ground Americano is the top choice to start a refined day. However, the taste of Americanos can vary greatly from one coffee shop to another. What kind of taste should a good Americano actually have?

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…]

Is it actually feasible to brew coffee with boiling water? Front Street Coffee previously pointed out in a tweet discussing water temperature that water temperature is not the only factor determining whether coffee is good or bad. This article further verifies: 100°C boiling water can absolutely brew good coffee, the key lies in adjusting the extraction plan. The article analyzes the risks brought by excessively high extraction efficiency at high temperatures, introduces response strategies such as shortening time, coarsening the grind, and adopting immersion extraction, and shares in detail the entire process and parameters of using the stirring method combined with 100°C water temperature to brew Sidamo·ALO beans. In the end, this cup of coffee had an extraction yield close to 21%, presenting a full-bodied juicy feel with mango, pineapple, and citrus flavors, and a finish with oolong tea aroma, receiving unanimous praise.

The collaboration between Gu Ming and the hit game "Honkai: Star Rail" ignited a consumer frenzy as soon as it launched, with over 1.2 million people queuing in the mini-program, and the topic quickly shot to the top of trending searches. Store orders poured in like snowflakes, and the limited-edition drinks were all fresh fruit smoothies with complex preparation processes. Under high-intensity operation, multiple smoothie machines were overwhelmed, emitting white smoke and even exploding on the spot, while staff were so busy they didn't even have time to drink water. To deal with equipment failures, some stores prepared backup machines in advance, while others had to borrow juicers from neighboring Shu Yi Shao Xian Cao and Luckin for emergency use. Behind this collaboration frenzy, issues such as excessively high thresholds for obtaining merchandise and enormous pressure on stores were exposed, also triggering discussions on optimization measures such as selling drinks and merchandise separately and cup storage services.
