Luckin Coffee's recently launched Fair Isle Latte has quickly become a new favorite among some office workers and tea-coffee enthusiasts, thanks to its flavor reminiscent of Assam milk tea and its powerful energizing effect.

This starkly contrasting feedback has plunged this new drink, which blends espresso with Ceylon black tea, into controversy.

Today, when Arabica and Robusta absolutely dominate global coffee supply, a species once forgotten for its poor flavor—Liberica (Coffea liberica)—is re-entering researchers' view. From 2021 to 2022, climate change-induced droughts tightened coffee inventories and sent prices soaring, with Arabica prices doubling in a short period. Facing the crisis of shrinking arable ranges, academia proposed three paths: relocating production areas, adjusting cultivation methods, and developing new crops. In December 2022, Nature Plants pointed out that Liberica might regain attention in an era of supply chain disruptions. One of its natural varieties, Excelsa, combines disease resistance, drought tolerance, low-temperature tolerance, and a flavor close to Arabica, and is being widely planted by coffee farmers in places such as Uganda. Front Street Coffee takes you through the full picture of this potential variety. [more…]

The "one bean, multiple brews" combo format has been appearing frequently on coffee shop menus in recent years. A pairing of one americano and one latte has caught many consumers' attention. However, the hulu combo cup designed specifically for combos has been exposed for quality issues — some netizens reported that the glass cup suddenly shattered while they were warming it, and customer service explained it was caused by excessive temperature difference. The merchant's product description did not indicate any usage restrictions or temperature tolerance range, which led many coffee enthusiasts to question: is a cup that can't even hold hot water really suitable for making coffee? This article will walk you through the origins of the combo, the original design intent behind the equipment, and this debate over aesthetics versus practicality. [more…]

Recently, the National Consumers League (NCL) filed a lawsuit against Starbucks in the Superior Court of the District of Columbia, accusing its "100% ethically sourced" marketing of deceiving consumers. NCL pointed out that Starbucks emphasizes ethical sourcing commitments in its marketing, yet fails to effectively address labor abuses such as child labor and forced labor in its coffee supply chain. Since 2015, Starbucks has claimed that 99% of its coffee is ethically sourced. Although its C.A.F.E. Practices program includes multiple indicators, investigative journalists in Brazil and elsewhere have still found violations at certified farms. Starbucks responded that it will vigorously defend itself and stressed that it works with farms to ensure compliance with standards. [more…]

The National Health Commission recently solicited public comments on 19 national food safety standards, among which the "Determination of Acrylamide in Foods" includes coffee within its testing scope for the first time, responding to the social debate sparked by the detection of acrylamide in freshly made and sold coffee. At the end of 2023, a report by the Fujian Provincial Consumer Council brought acrylamide in coffee into the spotlight; experts pointed out that this substance is a byproduct of high-temperature processing rather than an artificial additive, and that its content in coffee is extremely low, so there is no need for excessive concern about daily consumption. This revision of the national standard aims to improve the testing system, drive process improvements in the industry, and safeguard consumer rights. [more…]

Heytea recently launched a seasonal limited-edition drink, Litsea cubeba Yunnan papaya, combining western Yunnan sour papaya, Xishuangbanna litsea cubeba, Lingnan fresh carambola, and litsea cubeba pea jelly. Officially, it is positioned as having a distinctive sweet-and-sour taste. However, after the new product hit the market, evaluations on social media quickly split into two extremes: some were put off by the piercing sourness, some chose "less less less sweet" yet tasted only sweetness, and the sugar-free version was criticized for being overall too sweet with the fruit aroma not standing out. Why can the same cup of drink deliver such wildly different impressions as "sugar-free salted lemon Seven Up," "flat salt soda," and "hot and sour noodles"? This article sorts through feedback from all sides and explores how fresh fruit batches and individual differences in sourness tolerance affect the final flavor of this limited edition. [more…]

The freshly made yogurt sector has been hit by yet another food safety scandal. An undercover reporter from The Beijing News worked inside several More Yogurt franchise stores in Beijing and found that oat and highland barley toppings more than forty days past their expiration date were still being used as usual, expiry labels existed in name only, and decisions to scrap fruit relied entirely on staff members' sense of smell. More worrying still, these violations were not isolated cases, but an unspoken rule tolerated by store managers in order to cut costs and boost their personal income. The brand issued an urgent apology a few hours later, announcing that the stores involved would be permanently terminated. This is already the second time this year that More Yogurt has been thrust into the spotlight; previously, the Shanghai Consumer Council questioned the labeling of its product ingredients. This article provides a complete rundown of the undercover details, the brand's response, and the latest status of its stores. [more…]

In the global coffee-growing landscape, origins such as Brazil, Colombia, and Indonesia each have their own renown, while botanically coffee belongs to the Rubiaceae family under the genus Coffea, with over a hundred known species, though commercial cultivation is mainly concentrated in three varieties: Arabica, Robusta, and Liberica. Arabica is known for its elegant flavors and rich aromas, accounting for more than seventy percent of global production, and is often used for single-origin and specialty coffee; Robusta, on the other hand, is heat-tolerant, high-yielding, and highly stress-resistant, and is mostly used for instant coffee and espresso blends. This article systematically reviews the advantages and disadvantages of these two major varieties, the origins and flavor characteristics of common Arabica sub-varieties such as Typica, Bourbon, Catimor, and Maragogype, and introduces the Castillo variety bred from a cross between Arabica and Robusta, while also sharing related product experiences from Front Street Coffee in stores and during cupping.

Caffeine is the most iconic component of coffee, yet not everyone can tolerate it. It is both the primary source of bitterness and a neurostimulant that affects sleep. Thus, decaffeinated coffee was created to remove caffeine. However, the challenge of decaffeination lies in how to remove only the caffeine while preserving the aroma and flavor of coffee as much as possible. Early methods using organic solvents were effective, but left consumers concerned about residues. It was not until the advent of supercritical carbon dioxide extraction technology that a truly efficient and highly selective decaffeination process was achieved. This article will guide you through the principles of this technology, its development history, and its unique advantages in coffee decaffeination, while also introducing Front Street Coffee's attention to and practice of this process.

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…]
