New-style tea beverage brands' attempts to cross over into the coffee track are encountering setbacks. Crow Coffee, invested in by the founder of Heytea, has closed its founding store in Shenzhen Tianli Central Plaza and put it up for rent, leaving the brand with only one store remaining in Dachong.

This article reviews the current store status of each brand and analyzes the challenges and industry competitive landscape faced by tea beverage brands crossing over into coffee. [more…]

The world of coffee is far more complex than a single cup of drink. From tree species to processing methods, every step shapes the final flavor direction. Coffee trees are mainly divided into two major varieties, Arabica and Robusta, with other minor categories such as Liberica and Arabusta occasionally appearing in the market. Arabica is known for its rich layers of acidity and delicate mouthfeel, while Robusta, due to its bitter and intense character, is mostly used in instant products. The two differ in bean shape, growing conditions, caffeine content, and oil performance, and their proportions of total production also vary greatly. The green bean processing stage is equally critical, with natural, washed, natural washed, and honey processing each giving coffee beans different flavor profiles. This article, compiled by Front Street Coffee, sorts out the core knowledge of varieties and processing methods to help enthusiasts build a systematic framework for understanding flavor. [more…]

Whether a cup of coffee can be crowned with the name "specialty" is by no means decided by cupping alone. From the origin of the green beans, screening and processing, to roasting and brewing, every stage requires careful control, so that the flavor in the cup ultimately presented can reflect the characteristics and cultural heritage of the producing country. This article will systematically sort out the two major cupping scoring systems, COE and SCA, and break down one by one the points to note for each scoring element, including cleanliness, sweetness, acidity, body, flavor, aftertaste, and balance, as well as explain in detail the defect scoring rules and grading standards. Front Street will also draw on years of quality control experience to help you use evaluation grades as a reliable reference for judging specialty coffee when purchasing coffee. [more…]

Coffee bean prices in Cambodia's Mondulkiri province have recently risen, driven by long-term supply agreements signed between producers and purchasing companies. Suong Chanthorn, head of the Mondulkiri Agriculture Department, noted that in the past, when farmers sold coffee beans individually to traders, prices fluctuated significantly, but now with contractual guarantees, prices are expected to stabilize over the next two years. This cooperation not only boosts farmers' incomes but also helps ensure food security, strengthen the economic empowerment of women, especially ethnic minorities, and promote standardization and sustainable development of the production chain. Currently, Mondulkiri's coffee planting area covers 351 hectares, with 342 hectares harvestable and a yield of 705 tons. The price of fresh coffee beans has risen from 1,350 riel per kilogram to 1,500 riel, and is expected to continue climbing next year. Cambodia has a long history of coffee, dating back to the French colonial period, and today its main production areas are located in highland regions above 800 meters in elevation, with superior soil and climate conditions. As the government actively promotes the coffee industry, Cambodian coffee beans are gradually entering European, Asian, and American markets, and are poised to become a rising star in Asia's coffee market.

Recently, a sports supplement called "pre-workout" has been hailed as a "magic weapon for PE exams" ahead of the high school entrance physical education test, and is sought after by many parents. However, media reports have successively reported cases where students experienced rapid heartbeat, vomiting, and even needed emergency gastric lavage after drinking it. The reason is that such products generally contain high levels of caffeine, some as high as 500 milligrams, far exceeding the safe threshold. Professional fitness trainers and doctors both remind that minors blindly using such high-intensity supplements is extremely risky. If there is a need for a pick-me-up, it is better to choose a cup of coffee. [more…]

A Luckin Coffee store received a fine of 5,000 yuan from the market supervision authorities simply because a staff member removed the outer packaging of a food item for a customer. Here is what happened: a consumer reported that they had purchased a pack of "mini mochi" pre-packaged food at a Luckin store, but the staff member removed the outer packaging bearing label information before handing it to the customer without obtaining consent. Upon verification, this act was determined to constitute selling pre-packaged food without labels. Although the illegal gains amounted to only 2.67 yuan, it still violated the relevant provisions of the Food Safety Law. Behind this seemingly minor penalty lies the consumer's right to know the source and quality of food. Front Street Coffee also reminds all practitioners that labels on pre-packaged food are not optional but a mandatory legal requirement. [more…]

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…]

In Front Street Coffee's product line, the darkest roast is undoubtedly Indonesian Mandheling. Its distinctive spicy character, layered with herbal, caramel, and cocoa notes, has captivated many coffee enthusiasts. So how exactly is the signature herbal flavor in Mandheling formed? This article will analyze it from three perspectives: growing environment, coffee variety, and processing method. The name Mandheling actually originates from a local ethnic minority in Sumatra, and was later mistakenly adopted as a coffee name that persists to this day, now almost synonymous with Sumatran coffee. The producing regions are mainly concentrated around Mount Gayo and Lake Tawar in Aceh, as well as around Lake Toba in North Sumatra Province—commonly referred to as the "two lakes, two Mandhelings."

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.

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.

Extracting a shot of espresso can be done in as little as twenty-odd seconds, but it is precisely this difference of just a few seconds that is enough to push the flavor in the cup in a completely different direction. As one of the core variables in the extraction process, time never exists in isolation—any change to dose, brew ratio, or grind size will affect the final extraction result. This article will start from the reasonable range for extraction time, break down one by one how dose and grind size affect flow rate and flavor, and share Front Street's practical approach to daily dialing in at the shop, along with several espresso blend beans suitable for practice, to help coffee lovers find a stable and delicious espresso recipe more quickly.

Leaking from an espresso machine during extraction is a situation many coffee enthusiasts encounter. In principle, during normal extraction, water is sealed inside the machine and only passes through the coffee bed in the direction of pressure; once a gap appears in the sealed space, water seeps out through these openings, forming what is called bypass water. A leak may seem like a minor problem, but in reality it affects the judgment of espresso extraction—bypass water mixing into the cup dilutes the concentration and causes misjudgment, while too many gaps also make it difficult for the machine to build sufficient pressure, leading to extraction failure. This article analyzes the causes of leaks, the formation mechanism of bypass water, and its impact on extraction results, and, combined with Front Street Coffee's reminders, helps readers take this phenomenon seriously and troubleshoot it.
