Black tea is the most drunk tea in Britain and the dominant tea family on the world market. It's the same plant as green or white tea, Camellia sinensis, but processed differently. The leaves are withered, rolled, and crucially fully oxidised before being dried. Oxidation is what turns the green leaf brown black and gives the cup its strong colour, brisk character, malty body and distinctive ability to take milk well.
If you've drunk a builder's brew, an English breakfast, an Earl Grey, an Assam, a Darjeeling, a Ceylon, a Kenyan, an Irish breakfast or a Welsh breakfast tea, you've drunk black tea. It's the tea family the entire British supermarket aisle is built around, and the tea family that the standard kitchen kettle was designed for.
How black tea is made (and why it tastes the way it does)

Four steps separate green tea from black tea: withering, rolling, oxidation, and firing. The decisive step is oxidation. Once the rolled leaves are exposed to oxygen for several hours, enzymes inside the leaf convert the catechins (the green, vegetal tasting compounds) into theaflavins and thearubigins, the compounds responsible for black tea's amber brown cup colour, its tannic mouthfeel, and the brisk, slightly astringent character that takes a splash of milk so well.
Two production styles dominate the global supply:
- CTC (Crush Tear Curl) processing produces small, uniform pellets of leaf that brew fast and hard. CTC is what's inside almost every supermarket tea bag, Yorkshire, PG Tips, Tetley, Typhoo, Twinings English Breakfast, Lyons. The fast extraction is why a teabag brews a usable cup in three minutes.
- Orthodox processing keeps the leaves whole or only lightly broken. The result brews more slowly but with more nuance. Orthodox black teas are usually sold loose or in pyramid bags. Single estate Darjeelings and most Sri Lankan single origin Ceylons are orthodox.

| Origin | Character | Best for | Stocked from |
|---|---|---|---|
| Assam (India) | Malty, full bodied, dark amber cup, takes milk and sugar well | Builder's brew, breakfast tea, anything with milk | Backbone of every UK supermarket breakfast blend; Yorkshire Tea, PG Tips, Tetley |
| Darjeeling (India) | Light, floral, slightly muscatel, called the "champagne of teas" | Black no milk afternoon cup; collectors | Twinings range |
| Ceylon (Sri Lanka) | Bright, brisk, slightly citrussy, copper coloured cup | All day cup, with or without milk; iced tea base | Hyson (single origin from family owned gardens), Dilmah |
| Kenyan and East African | Strong, bright, fast extracting, slightly fruity | Bulk supermarket blends; the colour driver in builder's tea | Williamson Tea (single estate Kenyan), most supermarket budget blends |
| Chinese (Keemun, Yunnan, Lapsang Souchong) | Lighter body, smoother, sometimes smoky, often drunk without milk | Earl Grey base, after dinner cup, tea and pastry pairings | Twinings Lapsang and Earl Grey blends |
How to brew it properly

Black tea is the most forgiving family. Boiling water won't damage it. The risk runs the other way, lukewarm water leaves the cup thin.
- Temperature: 95 to 100°C, freshly drawn. See the water temperature guide for the full family by family detail.
- Steep: 3 to 4 minutes for a brisk cup; 4 to 5 minutes if you want full body and you'll add milk. Don't go past 5, the tannins start dominating.
- Leaf: One bag per mug, or 1g of loose leaf per 50ml of water (one rounded teaspoon per mug).
- Milk: Optional. A splash of whole milk softens the tannins and rounds the cup. Oat milk works particularly well with maltier blends.
For the proper builder's brew technique (more leaf, not longer time), see the strong builder's tea guide.
Caffeine in black tea

Black tea typically delivers 40 to 70mg of caffeine per cup, around half a cup of brewed coffee. The exact amount depends on the leaf, the steep time and the water temperature; longer steep + hotter water + finer leaf = more caffeine. For the breakdown by family and brand see the ultimate caffeine guide.
If you want black tea character without the caffeine, the decaf British teas guide covers the major UK decaf options. Black tea decaf goes through a CO2 or water process decaffeination that removes 99% of the caffeine while preserving most of the flavour.
Black tea vs green tea: the practical difference

Both come from the same plant. Black is fully oxidised, green is not oxidised at all. The cup level differences:
- Colour: Black is amber to mahogany; green is pale yellow to gold.
- Body: Black is full bodied and tannic; green is light and sometimes vegetal.
- Caffeine: Black 40 to 70mg; green 20 to 35mg per cup.
- Milk: Black takes it well; green does not, milk overwhelms the cup.
- Brewing: Black wants 100°C; green wants 70 to 80°C.
