Recently, a netizen in Fuzhou placed a cold Heytea drink, cup and all, into a microwave to heat it up. Just 30 seconds later, flames erupted inside the microwave, and the upper half of the cup was burned. The person involved described that halfway through heating, the microwave suddenly began crackling, and the moment it was opened, flames burst out. The fire only went out after the cup was knocked over with a spatula. Heytea customer service responded that the drink uses a paper cup containing metal materials, which is not suitable for microwave heating. In fact, many milk tea lovers on social media have a habit of directly heating milk tea, and similar dangerous incidents are not isolated cases. Whether brands should label packaging with microwave use warnings has also sparked discussions among consumers and legal professionals. [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.

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…]

A cup of pour-over coffee, from steaming hot to completely cold, undergoes irreversible changes in both aroma and taste. When the coffee drops to room temperature, most of those pleasant aromatic compounds present at high temperatures have long since dissipated, so it naturally tastes much flatter.
