Dirty coffee has become a staple in specialty cafes thanks to its high aesthetic appeal and unique taste, yet there has always been debate over whether an ice-cold cup is essential during preparation. Through side-by-side testing of glass cups at room temperature, refrigerated, and frozen, Front Street found that milk quality is the key to layering, while cup temperature mainly affects the chilled mouthfeel and the preservation of crema. The article also traces the practice of Dirty's originator, Katsuyuki Tanaka, who did not pre-chill his cup. If you're after photogenic presentation and a layered experience, Front Street recommends chilling the cup together with the milk and paying attention to the optimal tasting window. [more…]

The proliferation of single-use plastic cups is raising global concern, with governments and food service brands introducing restrictive measures.

Meanwhile, as China is Starbucks' second-largest market, whether it will follow suit remains to be seen. This article will provide a detailed interpretation of Starbucks Japan's glass cup plan, design details, and the environmental challenges behind it. [more…]

On the menu at Blue Bottle Coffee shops, there is a drink with a tongue-twisting name that is particularly intriguing—the Gibraltar. It is at once the name of a port city, the designation of Libbey's classic glassware series, and a rich little milk coffee that sits somewhere between a latte and a macchiato. This drink was not deliberately developed, but arose from an accidental purchase of the wrong glass: a 4.5-ounce small glass could not hold a regular milk coffee, yet it was just right for observing espresso crema, so a barista blended a small amount of thin-microfoam milk into a double espresso, accidentally creating an off-menu hit. Today, Front Street takes everyone through the origins of the Gibraltar, compares its similarities and differences with the cortado, and finally provides a home recipe with parameter references.

Dirty has always been a popular product in coffee shops thanks to its high aesthetic appeal and the unique experience of hot and cold colliding. When making a Dirty, using a chilled glass can extend the layering effect between the espresso and the milk, but should you use a refrigerated glass or a frozen glass? Through comparative experiments, Front Street Coffee found that although a frozen glass can widen the initial temperature difference, it also accelerates the dissipation of the layers, and the milk's mouthfeel and aroma are slightly compromised. The rise in popularity of -86°C Dirty has brought frozen glasses into the spotlight once again. This article explains in detail the differences between refrigerated and frozen chilled glasses, the points to note when making a Dirty with a frozen glass, and why purified milk is the best partner for a frozen glass, helping you fully understand the intricacies behind this dirty coffee.

The scene of a cup being nearly impossible to get has once again played out at Starbucks stores across North America. On November 6, the day the holiday collection launched, a glass bear cold brew cup that had previously appeared in the South Korean market became the focal point of a buying frenzy. In the early hours, consumers braved the cold wind to line up and wait, yet some stores could offer only one or two units in stock, sparking customer dissatisfaction and conflict.

Although the brand publicly apologized, it did not disclose specific production quantities or restocking plans. [more…]

Manner has always been known for its frequent free cup promotions, and the combination of set meals plus giveaways was once regarded by many users as a high-value choice. However, the recently launched retro glass cup giveaway unexpectedly fell flat—the cups the staff had prepared in advance went untouched, and the expected surge in orders never materialized. Why did a giveaway that was once so popular fail this time? A mix of factors is at play: the appearance not matching expectations, the set meal pairings not suiting people's tastes, the cup material not being heat-resistant, and consumers becoming increasingly rational. When buy-one-get-one promotions can no longer easily spark the urge to purchase, the promotional logic of coffee brands may be facing a turning point. [more…]
