OngTeh reference library
A world of tea, in one searchable atlas.
Explore 101 true teas, regional styles, herbal infusions and other brewed plants. Understand the caffeine difference and follow source-aware guides—not exaggerated health promises.
First, know your leaf
Tea and tisane are not the same thing.
True tea is made from Camellia sinensis and naturally contains caffeine. Rooibos, chamomile, lemongrass and peppermint come from other plants. Decaffeinated true tea can contain traces of caffeine; herbal blends may contain caffeine if they include tea, yerba mate or related plants.
