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.

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.

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.
