This is the classic, clear infusion made from the leaves of the Camellia sinensis plant, prized for its delicate, grassy, and slightly vegetal flavor profile. It's a virtually calorie-free beverage, offering a clean, refreshing taste with a subtle astringency that awakens the palate. Nutritionally, it's a powerhouse of polyphenol antioxidants, particularly catechins like EGCG, with no macronutrients to speak of.
People cherish green tea for its complex, umami-rich flavor that can be both soothing and invigorating, and for its central role in cultural rituals from Japanese tea ceremonies to Chinese gongfu cha. Its versatility allows it to be enjoyed hot or cold, plain or with a hint of lemon, making it a staple for mindful moments.
The tannins can inhibit non-heme iron absorption, so those with anemia should avoid drinking it with iron-rich meals. Caffeine-sensitive individuals may experience jitters or sleep disruption, especially with strong brews or late-day consumption. To mitigate, space tea consumption at least an hour from meals and opt for a lighter brew or decaf variety.
The same plant, Camellia sinensis, produces green, black, white, and oolong teas; the difference lies entirely in how the leaves are processed, specifically the level of oxidation.

Does green tea have more caffeine than coffee?
No. An 8 oz cup of brewed green tea typically has 25-50 mg of caffeine, while the same amount of coffee has 80-100 mg or more.
Can I reuse green tea leaves?
Yes, high-quality loose-leaf green tea can often be steeped 2-3 times, with each infusion revealing different flavor notes. The first steep is usually the most flavorful.
Is bottled green tea as healthy as brewed?
Often not. Bottled versions frequently contain added sugars and may have lower levels of beneficial catechins due to processing and storage.
