Approximately 50mg per 200ml cup brewed for 4 minutes from one Yorkshire Tea Original bag. Yorkshire Gold sits slightly higher at around 55-60mg because of the higher Assam content. Yorkshire Decaf is approximately 2-3mg, not zero. Source: Taylors of Harrogate manufacturer data, cross checked against Which? 2023 testing.

Approximately 40-45mg per 200ml cup from one Tetley Original bag, slightly lower than Yorkshire because the blend is lighter on Assam. Tetley Decaf is 2-3mg.

Approximately 45-50mg per 200ml cup from one pyramid bag. PG Tips uses Kenya led blends which sit between Yorkshire and Tetley on caffeine.

Yes, but not radically less. A bagged green tea is typically 30-40mg per 200ml cup, against 40-55mg for a bagged black. The difference is real but smaller than most people assume, switching from one strong black tea per morning to one strong green tea drops your daily intake by maybe 15mg.

No. Decaf processing removes 95-99% of caffeine, leaving 2-5mg per cup. Compared to a strong tea (50mg) or coffee (80-100mg) this is negligible, but it is not zero. Pregnant drinkers advised to limit caffeine to 200mg/day can drink decaf tea freely; people with severe caffeine sensitivity should drink herbal infusions (true zero caffeine) instead.

Strong Assam loose leaf brewed long is the highest commonly available tea, around 60-80mg per 200ml. Matcha tea has 60-70mg per bowl because you consume the powdered leaf. Yerba Mate (technically not tea but often listed as such) is around 80mg.

A typical filter coffee is 80-100mg per 200ml, espresso is 60-80mg per 30ml shot. So one filter coffee is roughly the same as two strong cups of black tea. Tea also contains L theanine which softens the caffeine release, most people report that two cups of strong tea feels less "jangly" than one filter coffee.
