The Henan Provincial Market Supervision Administration recently published its 2024 No. 39 food safety notice, showing that of 1,040 batches of food across 21 major categories sampled, a total of 24 batches failed. Among them, a "Yangtze River North Bank" oolong tea-flavored beverage, nominally produced by Xunxian Fuxinyuan Beverage Factory, was blacklisted because its total bacterial count did not meet national standards. An investigation found that the manufacturer not only had a prior record of product sampling failures, but was also ruled by a court to have infringed upon Nongfu Spring's packaging through counterfeiting, and has now been listed as a dishonest judgment debtor. More notably, the outer packaging of this oolong tea is highly similar to Suntory oolong tea, and many consumers who mistakenly bought it on e-commerce platforms complained loudly after being duped.

During the May Day holiday, "group leaders" in several Shanghai communities organized group buys of a Little Tea, with over 8,000 cups of drinks transported across provinces from out-of-town stores, arriving in consumers' hands overnight or even after nearly 24 hours. The group-buy price was double the official price, and the resellers were accused of profiting about 250,000 yuan. The total bacterial count in these milk teas rose sharply over time at room temperature, and some consumers developed gastroenteritis symptoms after drinking them. The Little Tea brand later issued a statement expressing shock at the high-priced reselling and reminding consumers to choose compliant channels carefully. This article reviews the course of the incident, the food safety data, and responses from all parties, while also offering coffee lovers Front Street Coffee's professional purchasing advice. [more…]

The new-style tea beverage industry has once again exposed food safety issues. Naxue's Tea's Shanghai East Changzhi Road store was fined and had its illegal gains confiscated by the Hongkou District Market Supervision Administration because the freshly made and sold Golden Mountain Treasure Tea exceeded the total bacterial count limit. Before this, the brand had already been exposed by the media multiple times for chaotic store hygiene, even alarming the State Administration for Market Regulation. From Xinhua reporters' undercover investigations to tea beverage brands frequently trending on social media across various regions, consumers pay high prices but do not necessarily receive matching safety guarantees. This article will sort out the ins and outs of this penalty, review the food safety crisis Naxue's Tea encountered this year, and ask: after tea beverage brands apologize, compensate, and rectify, have the fundamental problems actually been solved?

Nayuki Tea has once again been thrust into the spotlight due to food safety issues. The Market Supervision Administration of Jing'an District, Shanghai, recently imposed a penalty on Nayuki's Shanghai Meilongzhen Plaza store for selling expired grape-flavored cakes to consumers, with a fine of 50,000 yuan. This is not an isolated case—since its listing on the Hong Kong Stock Exchange in June this year, Nayuki's stores have repeatedly been exposed for food safety scandals such as cockroach infestations, spoiled fruit, and excessive bacterial counts. Consequently, its stock price has plummeted from the issue price of HKD 19.80 to around HKD 9, leading to a significant drop in market value. From being the "first stock of new-style tea drinks" to being plagued by negative news, Nayuki's brand reputation is facing a severe test. [more…]

This summer, bucket-sized fruit teas quietly took over milk tea shop menus. From Heytea and Nayuki to ChaPanda and CoCo, major brands have rolled out 1-liter or even larger bucket drinks, attracting consumers with high cost-performance. Bucket tea drinks are nothing new—back in 2019, they went viral thanks to Jay Chou fan support, and in 2020 Nayuki even launched a 5-liter "mighty bucket." However, issues like the short optimal drinking window and rapid bacterial growth in bucket tea drinks cannot be ignored. From giant buckets to portable packs, what evolution has bucket tea drinks undergone? And why have this summer's bucket fruit teas made a comeback? This article will break it all down for you.

Recently, the new-style tea beverage brand ChaBaiDao has frequently made headlines due to "large foreign objects" appearing in its drinks. From "real spider milk tea" to nail clippers, and now the latest cockroach incident, consumer complaints have been continuous. These incidents coincide with ChaBaiDao's plan to go public in Hong Kong, sparking discussions about its food safety management and whether there are malicious claims. This article reviews the detailed process of the ChaBaiDao cockroach complaint, analyzes the disagreement between the consumer's claim of 1,000 yuan and the merchant's offer of only 200 yuan, and explores the potential issues of insufficient employee training and "loophole attacks" under the Food Safety Law amid the rapid expansion of chain brands. At the same time, we will also focus on the current state of food safety in the industry and provide professional information for coffee enthusiasts. [more…]

In recent years, with the advancement of plastic restriction policies, plastic straws have gradually exited the food service scene, replaced by paper straws and PLA straws. However, paper straws easily become soggy, and PLA straws are not heat-resistant, greatly diminishing the consumer experience. A team led by Academician Yu Shuhong of the University of Science and Technology of China has taken a different approach, using bacterial cellulose combined with sodium alginate to develop an edible nata de coco straw. Its strength, modulus, and toughness are more than twice those of paper straws, it is thinner, and it can be made in different colors. Buried in soil, it nearly disappears in 45 days and completely degrades in 60 days. Can this new material save the afternoon tea joy of office workers? This article will provide a detailed interpretation. [more…]

Paper straws once swept through the food service industry in the name of environmental protection, yet they have been widely criticized for their poor mouthfeel and tendency to degrade in the mouth, and are now gradually exiting the market. Their replacement, PLA straws, are made from plant starch, are fully biodegradable, and withstand temperatures ranging from cold to hot drinks, but they have a short shelf life and relatively high cost. Meanwhile, research teams have developed edible bacterial cellulose-based straws that completely decompose within 60 days when buried in soil. From paper straws to PLA to coconut jelly straws, behind the iteration of eco-friendly straws lies a trade-off among cost, experience, and degradation performance. This article reviews the current state of paper straw production being discontinued, the market prospects for PLA straws, and the research progress on new edible straws, and includes Front Street Coffee's specialty bean news.

Many coffee enthusiasts, when tasting ice drip coffee, are surprised by its faint, elusive notes of wine aroma and character, even wondering if alcohol has been added, or if the coffee beans themselves carry a wine-like flavor. In fact, this unique flavor does not come from any added ingredient, but is closely related to the special way ice drip coffee is made. Freshly dripped ice drip coffee is actually thin in flavor and can even taste astringent; it needs to undergo sealed low-temperature aging to become mellow and layered. This article, drawing on Front Street Coffee's practical experience, will analyze the principles behind how the wine-like flavor of ice drip coffee forms, explain how low-temperature extraction inhibits bacterial growth, and why sealed refrigerated aging can produce a fermentation aroma similar to alcohol. It will also compare the uncontrollability of natural fermentation in hot-brewed coffee, helping readers understand how each step in making ice drip coffee affects the final flavor. [more…]

Cold brew coffee is often served in limited quantities in cafés because a single batch can easily take over eight hours to make. This cold coffee drink, which originated in Europe and is said to have been invented by the Dutch, is also known as DUTCH COFFEE. Because it relies on water dripping naturally through the coffee grounds and then falling drop by drop into the lower vessel to be collected, it is also called water-drip coffee. It is completely different from the simple method of adding ice to hot coffee: the former is low-temperature extraction, while the latter is brewed with hot water and then cooled. This article will cover the production steps of cold brew, bean selection ideas, drip rate control, refrigeration and aging, as well as the specific parameters for iced pour-over, to help coffee lovers clarify the differences between the two kinds of iced coffee, and provide Front Street Coffee bean recommendations and practical reference.

On a hot summer day, cold brew coffee becomes a favorite for many people. But how long can prepared cold brew be stored? What details should be noted when making ice drip and cold brew at home? This article provides a detailed explanation of the shelf life of cold brew coffee, the role of refrigerated aging, the flavor differences brought by different bean varieties, and the extraction parameters and grind size for ice drip and cold brew. At the same time, Front Street Coffee also gives specific suggestions based on the cold brew performance of its own beans such as Kenya, Strawberry Candy, and Gitiding Cooperative. Whether you are a beginner or a seasoned enthusiast, you can find practical references here. [more…]

Freshly brewed hot coffee often has a peak flavor window of less than an hour—once the aroma dissipates and the temperature drops, the taste degrades significantly. This is a common frustration for many coffee lovers. Is there a way to make coffee stay delicious for longer? The answer is to pour it into a thermos. The combined effects of sealing and insulation can significantly slow aroma loss and temperature decline, extending the enjoyable period to two or three times its original length. Front Street Coffee once conducted a test with Panama Boquete Geisha, and the results showed that coffee in a thermos performed excellently for the first two hours, began to decline noticeably by the third hour, and after about three hours was almost only flat. Of course, a thermos is not a cure-all—coffee stored too long in the bottle still carries a risk of bacterial growth, so drinking it as soon as possible is best. This article will explain from three aspects: principles, experiments, and practical suggestions. [more…]

Some may think that cold brew coffee is simply coffee grounds soaked in cold water for a long time. Actually, that's not the case! A delicious cold brew coffee involves more than just these elements; it also requires attention to some small details to assist our extraction. But as long as we do it right, we can easily make it with just a few steps. [more…]

Ice drip coffee and iced pour-over coffee are often mentioned together, but the two differ significantly in extraction principles, flavor expression, and brewing process. Ice drip is a low-temperature slow extraction, while iced pour-over is a high-temperature fast extraction followed by cooling. Temperature greatly affects the breakdown rate of oils, acids, and sugars in coffee, thereby shaping distinctly different aromas, mouthfeels, and layers. From the perspective of Front Street Coffee, this article systematically sorts out the respective characteristics of high-temperature extraction and low-temperature extraction, and, using Honduras Sherry coffee beans as an example, records in detail the brewing parameters and flavor comparison of ice drip and iced pour-over, helping coffee enthusiasts more clearly understand the essential differences between the two kinds of iced coffee. [more…]

What exactly is the difference between cold brew coffee and iced pour-over coffee? This is a question Front Street gets asked every day. Simply put, cold brew is a low-temperature slow extraction, while pour-over is a high-temperature fast extraction, and the two present distinctly different characteristics in flavor and mouthfeel. This article will start with the influence of temperature on extraction, analyze in detail the respective features of high-temperature extraction and low-temperature extraction, then use the Sherry coffee beans from the Honduras Mocha estate selected by Front Street Coffee as a sample to demonstrate the complete brewing processes of cold brew coffee and iced pour-over coffee, including key technical parameters such as coffee-to-water ratio, grind size, and pouring technique, and compare the flavor differences ultimately presented by the two methods, helping coffee lovers find the cup of icy good coffee that suits them.

As soon as summer arrives, for coffee lovers, nothing is better than a refreshingly icy cold coffee. If you reject high calories, care about mouthfeel and lingering finish, and love to explore and try new things, in summer you can try the goddess-level drinks in the iced coffee world, "Ice Drip Coffee" and "Cold Brew( [more…]

Many people tasting cold drip coffee for the first time are surprised: is there alcohol in this cup of coffee? In fact, that boozy note does not come from alcohol, but is the result of the unique cold drip extraction method combined with subsequent low-temperature aging. Starting from Front Street Coffee's actual cold drip coffee-making parameters and drawing on chemical principles, this article explains how ester hydrolysis produces the alcohols responsible for the wine-like aroma, while comparing the differences with the natural fermentation of hot-brewed coffee, and gives the optimal drinking window and safety recommendations for cold drip coffee. [more…]

As temperatures drop, pour-over coffee quickly goes cold. Front Street Coffee conducted an experiment using a washed Yirgacheffe Gedingding, pouring freshly brewed coffee into a 316 stainless steel thermos and sealing it, then measuring the temperature and tasting the flavor hour by hour. At 1 hour, 65.8°C, it still retained floral and citrus notes; at 2 hours, 60°C, there was almost no change; at 3 hours, 54°C, the flavor was slightly weaker; at 4 hours, 50°C, the floral notes had dissipated and the acidity and sweetness became more prominent; at 5 hours, 46°C, only honey green tea and citrus acidity remained. The test shows that a qualified thermos can preserve the flavor well for 2-3 hours, making it suitable for taking to work, but after 4-5 hours the drop in temperature makes it prone to bacterial growth, so long-term storage is not recommended.
