When the December cold wind picks up, friends who order hot coffee delivery start worrying again: by the time it arrives, it's often just lukewarm, and drinking it is really not comforting enough. To preserve that warm sip, coffee shops are pulling out all the stops. Recently, netizens noticed that Manner's baristas wrap each hot delivery cup in shiny silver foil, as if adding a winter coat to the cup—a sight that is both surprising and a bit amusing. Some joked that spending ten yuan on a coffee actually gave them the feeling of being cherished. Is this layer of foil just for show, or can it really lock in the heat? Consumer feedback is almost unanimously one-sided: when peeling off the foil, the contents are shockingly hot, so much so that you have to turn on a fan to cool it down. In fact, this is not Manner's first year trying it out; it was already implemented last year. Behind heat preservation lies a common drinking principle: as temperature drops, acidity and bitterness become more pronounced. Is Manner's move just formalism or a scientific plus? Front Street is here to take you on a deep dive. [more…]

As the weather turns cold, hot milk tea tends to get cold during delivery, and many consumers try to reheat it in a microwave, only for accidents to happen frequently. Recently, multiple customers have reported that when heating Jasmine Naibai drinks, the paper cups showed burn marks and even nearly caused a fire. In contrast, heating milk tea from brands such as Bawang Chaji, Mixue Bingcheng, and Nayuki did not cause similar problems, raising questions about the quality of Jasmine Naibai's paper cups. However, onlookers rushed to defend the brand, pointing out that the cup sticker already has a reminder, and that the metallic substances in the cup's gold-stamped pattern reflect microwaves in the microwave, which is the main cause of the accidents. This article reviews the course of the incident and the underlying principles, and reminds readers: heating milk tea in a microwave poses safety hazards, so do not imitate it rashly. [more…]

However, once merchandise has quality problems, after-sales disputes follow one after another.

Green coffee beans are the starting point that determines the flavor of a cup of coffee. From color and luster to moisture content, every detail reveals the quality code of green beans; the terms "new crop," "current crop," "old crop," and "aged crop," named by harvest year, record how time shapes flavor.

The ultimate preservation challenge points to a simple yet expensive answer: vacuum packaging followed by freezing. This article systematically organizes the complete knowledge of green beans from identification to storage, and includes practical advice from Front Street Coffee, taking you deeper into understanding this green seed.

After the weather turns cold, many coffee enthusiasts find that using the same brewing parameters makes their coffee taste weak and lacking in sweetness. The problem often lies in the water temperature—a low-temperature environment accelerates heat loss, causing the actual extraction temperature to be lower than expected. Through actual testing, Front Street has found that at the same initial water temperature, there is a clear difference in the temperature of the coffee bed between summer and winter. This article will analyze the gap between the water temperature in the kettle and the extraction temperature, provide specific recommendations for adjusting water temperature in winter, and share practical techniques to reduce heat loss, helping you consistently produce a cup of pour-over coffee with full flavor even in the cold season.

The chain milk tea brand Grandpa's Tea launched a limited-edition garden thermos to celebrate its sixth anniversary, attracting many fans to collect the merchandise. However, some consumers discovered rust at the rim of the cup along with a strange odor after use, raising concerns about product quality.

Front Street Coffee reminds coffee lovers that when choosing a thermos, they should pay attention to material and craftsmanship details, and promptly defend their rights if they encounter quality issues.

Recently, some consumers reported that when buying a cup of Yidiandian milk tea at a store, staff actually packed the drinks in thin transparent plastic bags or even black garbage bags, sparking heated discussion online. Behind this is not stinginess on the part of the store, but the fact that the paper bags promised by headquarters as replacements had still not arrived, leaving some stores in the awkward situation of "having no bags to use." Employees revealed that before the Chinese New Year, headquarters notified them that plastic bags would be replaced with paper bags, but there has still been no sign of them, and they were instead told they would have to wait until April. During this period, they went through the Chinese New Year and Valentine's Day consumption peaks, and many stores saw their packing bag inventories run critically low. At a time when many chain brands are launching co-branded paper bags, Yidiandian's insistence on plastic bag packaging has also sparked polarized discussion among fans. This article will walk you through the whole incident and the reactions from all sides. [more…]
