An 8 oz cup of English breakfast tea holds about 47 mg of caffeine, roughly half of what you get from the same size cup of coffee. That is the number Twinings publishes for their blend, 47 mg per cup against 95 mg for coffee. It lines up with USDA FoodData Central, which puts brewed black tea at 47 mg per 8 fl oz. English breakfast is a black tea blend, so it carries whatever caffeine its black tea leaves carry, and the number moves with how you brew it.
Why English breakfast tea is not a caffeine outlier
English breakfast is a blend, usually Assam, Ceylon, and Kenyan black teas married together for a strong, malty cup that stands up to milk. The name suggests something special is going on, but the caffeine comes from the tea leaf, same as any other black tea. There is nothing in the blending that adds or removes caffeine. That is why the published figure sits right on top of the generic black tea number.
The Twinings FAQ gives a working range for unflavoured black tea of 40 to 76 mg per serving, measured as one bag steeped in 200 ml of water. English breakfast sits inside that band. Where your cup lands depends on steep time, leaf mass, and water temperature, not the words on the box. A quick two minute dunk pulls less caffeine. A five minute steep at a full boil pushes toward the top of the range and gets that brisk, tannic edge the blend is known for.
English breakfast tea caffeine compared to coffee and other black teas
Here is how a cup stacks up against the drinks people usually swap it for. All tea and coffee figures are per 8 fl oz unless noted.
| Drink | Caffeine | Source |
|---|---|---|
| English breakfast tea (average cup) | 47 mg | Twinings |
| Brewed black tea, general | 47 mg per 8 oz | USDA FoodData Central |
| Unflavoured black tea (per 200 ml bag) | 40 to 76 mg | Twinings FAQ |
| Yorkshire Tea / strong breakfast blends | top of the 40 to 76 mg band | Taylors of Harrogate, Twinings range |
| Brewed coffee | 95 mg | Twinings |
The headline comparison is simple. Twinings puts English breakfast at about half the caffeine of coffee, cup for cup. Against other black teas there is barely any gap, because they all draw from the same leaf. A strong breakfast blend like Yorkshire Tea from Taylors of Harrogate uses more leaf and brews robust, so it lands at the upper end of that 40 to 76 mg band rather than in a separate category. Earl Grey, being flavoured, actually runs a touch lower because the bergamot oil takes up room the leaf would otherwise fill.
Worth flagging the serving size trap. The FDA quotes black tea at 71 mg, but that is for a 12 oz serving, which works out to the same 47 mg per 8 oz. When a chart looks high, check whether it is measuring a bigger cup.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.
What actually moves the number in your cup
Three things change English breakfast caffeine more than the brand. Steep time is first. Twinings notes the longer the steep, the more caffeine extracts, and recommends three to five minutes for black tea. Pull the bag at two minutes and you get a lighter, lower-caffeine cup. Leave it in for six and you push the top of the range along with the astringency. Second is leaf mass, so a double-bagged builder's brew runs higher than a single bag. Third is water temperature, black tea wants a full rolling boil, and cooler water pulls less caffeine and less flavour together.
Milk and sugar change none of it. A splash of milk in your English breakfast, the standard way most people drink it, adds a little calcium and calories but zero caffeine. If you order it as a latte or a concentrate at a shop, the caffeine only climbs when they use more tea, not more milk. And decaf English breakfast is not zero either. The process strips most of the caffeine but leaves a trace, so it counts as near zero rather than truly caffeine free.

FAQ
Does English breakfast tea have as much caffeine as coffee? No. Twinings puts an average cup at 47 mg against 95 mg for coffee, so roughly half. A very strong, long-steeped brew narrows the gap but does not close it.
Is English breakfast tea stronger in caffeine than other black teas? Not really. It draws from the same black tea leaf, so it sits inside the 40 to 76 mg per serving range Twinings gives for black tea. Robust breakfast blends land at the top of that band, not above it.
How can I make my English breakfast tea lower in caffeine? Steep it for a shorter time. Twinings notes caffeine extraction rises with steep length, so pulling the bag at two minutes instead of five gives you a milder cup. Cooler water or a single bag helps too.
