True tea, fully oxidized

Black tea

Reviewed May 2026

Black tea is fully oxidized, giving it more body, color, and tannin. It is the backbone of breakfast tea, iced tea, Earl Grey, and many chai blends.

What is black tea?

Black tea is tea from Camellia sinensis leaves that are fully oxidized before drying. That oxidation gives black tea its darker color, fuller body, brisk tannin, and the malt, citrus, honey, spice, or dried-fruit flavors common in breakfast tea, Earl Grey, iced tea, and many chai blends.

Common questions

Does black tea need boiling water?

Many black teas tolerate near-boiling water better than green tea, but delicate Darjeeling or lighter styles may taste better slightly cooler.

Is black tea good with milk?

Often, yes. Assam, breakfast blends, Ceylon, and chai-style teas are common milk-friendly directions.

Is black tea a good base for chai or milk tea?

Yes. Strong Assam, Ceylon, English Breakfast, and many other black tea blends are common bases because they keep enough body after milk, spice, ice, or sweetener is added.

Why is black tea dark?

Black tea is dark because the leaves are fully oxidized before drying. That processing deepens the liquor color and creates the fuller body and brisk tannin people expect from black tea.
