As coffee consumption becomes increasingly widespread, food safety has naturally become a focal point of public attention. Recently, a post circulating on social media questioned whether the white spots on ice cubes in beverages were mold, quickly sparking heated discussion among netizens. In response, Luckin officially stated that the ice cubes have a hollow structure, and when preparing drinks, air or foam enters the grooves, causing light refraction that visually appears as white spots, which disappear after stirring. Meanwhile, an on-duty barista came forward to detail Luckin's ice machine cleaning procedures and handwashing standards, vigorously proving that the store's hygiene standards are strict. Whether this incident stems from consumer misunderstanding or hidden hygiene risks, opinions vary. Front Street will also continue to monitor food safety developments in the coffee industry, providing reliable information for enthusiasts. [more…]

When drinking iced coffee in summer, it tends to become diluted toward the end, so some people have thought of using stainless steel ice cubes instead of traditional ice. Are these reusable metal ice cubes really suitable for coffee? Front Street conducted an actual comparison test, analyzing the structure of stainless steel ice cubes, their cooling speed, and their impact on flavor. The results show that although stainless steel ice cubes have the advantage of not melting, their cooling effect is far inferior to homemade ice cubes, especially performing poorly in the ice pour-over step. The article also shares a pour-over plan using a mix of the two types of ice cubes, and explores why coffee shops rarely use stainless steel ice cubes. [more…]

On a scorching summer day, you want to drink iced pour-over but worry the flavor will be watered down, so a friend suggests: use stainless steel ice cubes to cool down hot pour-over—wouldn't that give you both full flavor and a refreshing chill? This idea sounds beautiful, but through comparative experiments, Front Street Coffee found that although stainless steel ice cubes can preserve coffee concentration, they fall short of traditional ice cubes in temperature and mouthfeel. This article documents in detail the parameter differences between regular iced brew and the experimental iced brew with stainless steel ice cubes, the actual measured temperature results, and the inherent shortcomings of stainless steel ice cubes—slow cooling and not cold enough—to help you decide whether they are worth using in iced pour-over.

Luckin's cold drinks do not offer a "no ice" option, and the problem of excessive ice has repeatedly trended on social media. To get a drink that suits their taste, consumers have begun to "report" the exact number of ice cubes in the remarks section, and even make various demands about the shape and temperature of the ice, leaving store employees utterly exhausted. From "less ice, 10–12 cubes" to "two little heart-shaped ice cubes," and even "no ice but with a frosty feel," these bizarre remarks not only reflect consumers' obsession with ice levels but also push Luckin's workers into a dilemma where "whatever they do is wrong." This article compiles a large number of real order remarks, presenting this tug-of-war over ice cubes. [more…]

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…]

Iced pour-over coffee needs rapid cooling, but ordinary ice cubes melt and dilute the coffee's strength. Some friends suggested using non-melting stainless steel ice cubes, but that attempt failed; then someone else recommended dry ice, which cools quickly and doesn't cause dilution. Dry ice can indeed chill coffee rapidly without turning into water, but when it sublimates it releases carbon dioxide, which dissolves into the coffee and turns a cup of iced pour-over into carbonated coffee—essentially deviating from what's wanted. This article provides a detailed analysis of dry ice's physical properties, its everyday uses, and why it's unsuitable for making pour-over coffee, along with Front Street Coffee's key points from their dry ice experiments and a recommended bean list.

On a scorching summer day, iced coffee naturally becomes a hot topic of discussion among coffee lovers. Some coffee enthusiasts have raised the question: for iced pour-over coffee, is it better to simply add ice to dilute it, or to let the coffee liquid flow over ice to dilute it?

Cold brew coffee is popular in summer and usually requires steeping coffee grounds in the refrigerator for 12 to 18 hours. Although it takes a long time, the flavor is outstanding. Compared with hot coffee, iced coffee is more like a dessert in a cup. With ice cubes, coffee, flavored syrup, and dairy products added, the combinations are rich and easy to make at home. Choosing the right coffee beans is key. Deep-roasted Front Street Brazil coffee and Front Street Mandheling coffee are both good base choices; if you prefer floral cold brew, Front Street Fruit Ding Ding can be the first choice, if you want black coffee with obvious fruit flavor, buy Front Street Strawberry Candy, and if you are after ripe tropical fruit notes, Front Street Xizhua is recommended. In addition, the type of ice cubes affects the drinking experience, and the storage time of leftover cold brew coffee also needs attention. Front Street suggests drinking low-temperature extracted coffee within 5 days. [more…]
