Beginner’s guide to tea types

Tea comes from the Camellia sinensis plant. How the leaves are processed—oxidized, steamed, dried—determines whether you get black, green, white, or oolong. Herbal “teas” are infusions of other plants and aren’t tea in the strict sense, but they’re part of the same drinking tradition.

Black tea is fully oxidized. It’s bold, often malty or brisk, and has the most caffeine among classic teas. Great in the morning or when you want a strong flavor.

Green tea is heated soon after harvest to stop oxidation. It stays lighter in color and flavor, with grassy or vegetal notes. Caffeine is moderate. Drink it in the morning or afternoon.

White tea is made from young buds and minimal processing. Delicate and subtle, with less caffeine. A good choice for afternoon or evening if you’re sensitive to caffeine.

Oolong sits between green and black: partially oxidized. It can be floral, fruity, or toasty depending on the style. Versatile for any time of day.

Herbal teas (chamomile, peppermint, rooibos, etc.) are caffeine-free. Use them whenever you want flavor and comfort without affecting sleep. Mix and match types according to the moment—Teagenie can help you choose.
