A delicate, pale-green infusion made from unoxidized Camellia sinensis leaves, known for its subtle, grassy, and slightly sweet flavor with a light, clean mouthfeel. With zero calories, protein, carbs, fat, fiber, or sugar per 100g, it is a pure, hydrating beverage that delivers a gentle caffeine-free lift. Its vibrant, vegetal aroma and smooth finish make it a staple for mindful sipping.
💚 Why it's loved
People love it for its clean, refreshing taste that pairs beautifully with light meals, desserts, or simply as a calming ritual. Its versatility allows it to be enjoyed hot or cold, and its cultural significance in East Asian traditions adds a layer of mindfulness and heritage.
⚠️ Watch-outs & how to enjoy it better
Some find the grassy or vegetal notes too mild or astringent, and it can be sensitive to over-steeping, which makes it bitter. For those with iron absorption concerns, the tannins in green tea can inhibit iron uptake, so it's best consumed between meals rather than with iron-rich foods.

FAQ
Is decaffeinated green tea completely caffeine-free?
No, decaffeinated green tea typically retains 2-5% of its original caffeine, so it may contain 2-10 mg per cup, compared to 25-50 mg in regular green tea.
How does decaffeination affect the flavor and nutrients of green tea?
Decaffeination can slightly reduce the tea's antioxidant content and alter its flavor, making it milder and less astringent, but it still retains most of its beneficial compounds.
Can I drink decaffeinated green tea before bed?
Yes, it's generally safe for evening consumption due to its low caffeine content, but individuals sensitive to caffeine may want to avoid it close to bedtime.
