The SCAA Coffee Flavor Wheel is a core tool for specialty coffee enthusiasts to identify flavors, yet many people are still unfamiliar with it. This article systematically breaks down the left-right structure of the flavor wheel: the right side, the normal flavor spectrum, reveals the three major aroma sources of fermentation, sugar browning, and dry distillation, while the left side, the negative flavor spectrum, corresponds to the defective flavors produced by improper green bean processing, storage, and roasting. It also explains in detail the deduction rules for different defects in SCAA cupping—serious defects deduct 4 points, minor defects deduct 2 points—and how roasting and organic matter loss, although not deducting defect points, can lower flavor performance. The article includes the latest high-definition Chinese-English flavor wheel images and retains Front Street Coffee's communication channels, making it suitable for readers who want to gain a deeper understanding of coffee sensory evaluation.

Cupping began as a quality control method used in the trade to verify whether coffee beans met standards.

At present, the two globally recognized authoritative scoring systems come from the SCAA and the COE. This article focuses on the SCAA cupping scoring system, breaking down one by one its eleven scoring dimensions, the required number of sample cups, the division of score ranges, and how defect deductions are calculated, to help readers fully understand how a cup of coffee is quantified into a score.

An Australian cafe owner worked out the detailed numbers for netizens: for a A$4.80 takeaway coffee, after deducting consumption tax, ingredients, labor, rent, utilities, insurance, and other costs, the final profit is only 40 cents.

Brazil, as the world's largest producer of Arabica coffee, accounts for about thirty percent of global coffee consumption. Its coffee industry relies not only on its unique geographical and climatic conditions but also on industrialized operational models that have created considerable economic benefits. Brazilian specialty coffee is mainly rooted in regions such as Minas Gerais, São Paulo, Paraná, and Mogiana.

When tasting coffee, flavor and mouthfeel are usually the first focal points, but there is another relatively abstract yet crucial dimension—balance. It does not mean blandness or absolute equivalence, but rather an overall state of harmony in which the acidity, sweetness, bitterness, and other elements in the coffee coordinate with one another, with none being overly prominent or too weak. Balance involves not only taste, but also mouthfeel, finish, and performance at different temperatures. This article will start with the definition of balance and the criteria for judging it, and recommend several Front Street Coffee beans with excellent balance, helping readers gain a comprehensive understanding of this concept.

The Starbucks app recently completed an upgrade, officially adding the Diamond tier to its membership system, and simultaneously launched a limited-time lottery event where members can participate using stars. The top prize of 888 stars looks tempting—converted at 9 stars for a grande beverage, that's equivalent to 98 free coffees. However, many users only discovered after spending their hard-earned stars that most results merely returned a small number of stars valid for just two weeks, or even came up empty-handed. The odds of winning, the expiration period of rewards, and issues like accidentally tapping and having stars automatically deducted have led some people to jokingly call this event a "star recycling program."

Recently, a post about a Luckin Coffee store refusing to provide ice to a customer for her child to use as a cold compress to reduce swelling sparked widespread discussion online. The customer, whose child had suffered a head injury and urgently needed ice, was politely declined by staff citing company policy, and was suggested to seek help at the KFC across the street. Behind this incident lies the dilemma that chain beverage brands face between food safety control and customers' emergency needs. Luckin employees revealed that the rule against providing ice separately stems from a previous incident in which someone sent store ice for testing, triggering an economic dispute. Since then, bar-counter surveillance has been monitoring in real time, and those who violate the rule may face bonus deductions. However, when customers face special emergencies, should there be room for flexibility? Front Street Coffee takes you into an in-depth discussion of this topic. [more…]

On a scorching summer day, iced drinks become the top sellers at beverage shops everywhere, yet the debate over "can you order it without ice" never dies down. A customer ordered an iced drink at Manner, noting that they only wanted two ice cubes, but after receiving it still found the temperature too low and asked the staff to remove the ice, only to be refused.

Similar situations have occurred at Starbucks. Why are chain brands so "particular" about the amount of ice? And how should baristas choose between customer needs and company rules? This article will guide you through the industry logic behind the controversy over removing ice from iced drinks. [more…]

How much can you actually lose by opening a coffee shop? Many shop owners have shared their real earnings on delivery platforms: a cup of coffee originally priced at over twenty yuan, after deducting various discounts and commissions, may leave them with only a few cents, or even result in negative-order losses.

During peak periods of exploding orders at tea beverage stores, staff inevitably make small mistakes such as forgetting to include straws, failing to affix expiration date labels, or knocking over tea containers, which are usually addressed with internal reminders or minor penalties. However, after employees at some Gu Ming stores filmed mocking videos featuring staff wearing placards around their necks, which were shared on social media, they sparked strong backlash from numerous netizens due to scenes involving employees having "crime" cardboard signs hung on their chests and their hands being cuffed with cup holders. The controversy centers on whether this form of imitation public shaming respects workers and whether it was appropriate for the official account to participate in posting it. Gu Ming subsequently responded that the video borrowed from a popular platform meme, has taken down the related content and apologized, and also distributed a thousand free drink vouchers. [more…]
