What is Decaffeinated Tea? Definition, Benefits, and a Guide to Choosing Herbal Teas | CATTEA®
Many mistakenly believe that all beverages named "tea" contain caffeine, but this is not the case. For those pursuing a clean diet, adjusting their routines, or sensitive to caffeine, understanding the definition and classification of "caffeine-free tea" is the first step toward choosing healthy beverages.
CATTEA® meticulously selects local Taiwanese flowers, fruits, and herbs to compile a knowledge system of caffeine-free teas for you, allowing you to confidently enjoy a cup of tea that echoes the aromas of the land at any time.
01. What is Caffeine-Free Tea?
Scientific Definition:
Any brewed beverage whose raw materials do not contain naturally caffeinated plants such as the tea plant (Camellia sinensis), coffee plant, cacao plant, or yerba mate plant is considered "naturally caffeine-free tea." These non-tea plant infusions are often referred to as "Tisane" or "Herbal Tea" in the West, to distinguish them from traditional tea leaves.
Common black tea, green tea, and oolong tea all originate from the leaves of the tea plant and thus naturally contain caffeine. In contrast, fruit and flower teas, and herbal teas are based on flowers, fruits, roots, stems, or non-tea plant herbs, and are naturally caffeine-free.
Additionally, "Decaf Tea" commonly found on the market, still uses traditional tea plant leaves as its raw material, but has most of its caffeine removed through physical or chemical processing. Consumers should note that decaffeination technology cannot achieve 100% removal, so these teas are not completely caffeine-free and will still contain trace amounts of caffeine, making them low-caffeine beverages.

Common caffeine-free ingredients include: blueberries, citrus, lemon, hibiscus, mint, lemongrass, perilla, indigenous cinnamon, black beans, black rice, roses, chrysanthemums, etc. Rooibos tea, though called "tea," comes from a legume shrub and is also a non-tea plant.
