In the afternoon, you invite a friend to grab coffee, only to be politely turned down with "I'm afraid I won't be able to sleep tonight"—and instead, they order a milk tea. Sound familiar? But what you may not know is that milk tea also contains caffeine. Caffeine is a natural stimulant found widely in more than sixty plants, including coffee beans, tea leaves, kola nuts, and cacao beans, and it also appears in synthetic form in medications, energy drinks, and even chewing gum. Caffeine content varies considerably across different beverages: a roughly 225-gram cup of coffee contains 95 to 200 milligrams, a 340-gram can of cola about 35 to 45 milligrams, a 225-gram can of energy drink about 70 to 100 milligrams, and a 225-gram cup of tea between 14 and 60 milligrams. This article walks you through how caffeine is absorbed in the body, when it peaks, and its half-life, as well as which factors determine how quickly it is fully metabolized, helping you schedule your coffee and milk tea more scientifically.

Tea is both an everyday beverage and something that can affect rest at night.

Lawmakers in Hawaii's Kona coffee region have recently introduced a series of bills aimed at imposing stricter labeling rules on single-origin coffee and blends containing Hawaii-grown coffee. The core change in the proposals is that the proportion of coffee from a designated region in a blended product would need to rise from the current 25% to 100%, multi-region Hawaii coffee blends would have to list the proportion of each region one by one, and when Hawaii coffee is blended with coffee from other countries, the percentage and Hawaii origin information would also have to be labeled. Accompanying bills also set out enforcement mechanisms, with a proposed fine of $10,000 for each violation. Behind this move is the labeling reform effort that Kona coffee growers and lawmakers have continued to push since 2015, as well as the legal foundation established by a class-action lawsuit involving giants such as Walmart, Amazon, and Costco.
