There’s good news for tea drinkers who are sensitive to caffeine or simply prefer to limit their intake. Thanks to a wide variety of low- and no-caffeine alternatives, you don’t have to give up tea entirely.

Tisanes—more commonly known as herbal teas—are an excellent alternative to traditional tea, all of which naturally contains caffeine. Popular options include chamomile, peppermint, and blends featuring hibiscus, rose hips, and other botanicals.

Most tisanes are naturally caffeine-free. Rooibos and honeybush, both originating from South Africa, are particularly popular choices because they offer a flavor profile somewhat similar to traditional tea, without the caffeine.

Strictly speaking, “tea” refers to beverages made from the leaves of the Camellia sinensis plant. All true teas—whether black, green, white, or oolong—contain caffeine. The only exception is decaffeinated tea, which has undergone processing to remove most of its caffeine content.

In the United States, a tea must have at least 97% of its caffeine removed to be labeled as decaffeinated.

There are two primary methods used to remove caffeine from tea. One method uses pressurized carbon dioxide, which selectively removes caffeine while preserving much of the tea’s original flavor. Another method involves chemical solvents such as methylene chloride or ethyl acetate. While effective, these methods are sometimes viewed as less desirable by tea purists.

A commonly circulated idea suggests that rinsing tea leaves in hot water for about 30 seconds can significantly reduce caffeine content. However, this method is widely debated. Many experts believe it removes flavor along with only a small portion of the caffeine.
