Canonical: https://teas.co.uk/wiki/english-breakfast-caffeine/\nLast reviewed by the teas.co.uk team in April 2026.\nEnglish Breakfast Tea contains 40-50mg of caffeine per 200ml cup, brewed for 4 minutes from one standard tea bag. The exact figure varies by brand, Yorkshire Tea is at the higher end (50mg), Tetley is at the lower end (40-45mg), Twinings sits in between. This is the working caffeine guide for the UK's most drunk tea. The number, broken down \n\"English Breakfast\" isn't a single tea, it's a blend, and different brands use different ratios.

CTC (small pellets) extracts faster and more completely than orthodox (full leaf). Most EB blends use CTC. Bag fill. Premium brands typically use slightly more tea per bag. Yorkshire bags are notably full. Source variability. Even within one brand, batch to batch caffeine varies based on harvest conditions.\n Brewing changes the number \n\nSource: Teas.co.uk.

About a third to half the caffeine of filter coffee.\nDoes EB have less caffeine if I brew shorter? Yes, 2-minute brew has ~30% less caffeine than 4-minute brew.\nIs decaf EB safe in pregnancy? Yes, 2-5mg residual is well within NHS limits. Curator's note: most British drinkers underestimate how quickly caffeine adds up across the day. Four cups of Yorkshire Tea = 200mg.
