Approximately 50mg per 200ml cup brewed for 4 minutes from one Yorkshire Tea Original bag. Source: Taylors of Harrogate manufacturer data, cross checked against Which? 2023 caffeine testing. For comparison, a cup of filter coffee is 80-100mg, an espresso is 60-80mg per shot.

55-60mg per 200ml cup. Slightly higher than standard Yorkshire because the Gold blend contains a higher proportion of Assam tea, which is naturally higher in caffeine than Kenya or Ceylon.

Approximately 2-3mg per 200ml cup. Decaffeination removes 95-99% of the caffeine, leaving a small residue. Compared to a strong tea (50mg) or coffee (80-100mg) this is negligible, but it is not zero.

Yes, completely. Bedtime Brew contains no Camellia sinensis (tea) base, the malty body comes from chicory and roasted ingredients, not from black tea, so there is no caffeine to remove. Suitable for evening drinking or pregnancy without restriction.

No. A typical cup of Yorkshire is 50mg; a typical cup of filter coffee is 80-100mg, roughly twice as much. An espresso is 60-80mg per 30ml shot, but most people drink coffee in larger volumes than tea, so the per drink caffeine load is higher with coffee.

Roughly 15-30 minutes for the noticeable effect, peaks at 30-60 minutes, half life around 5 hours. The L theanine in tea (which coffee lacks) softens the caffeine release, so the effect is steadier and less jittery than the equivalent dose from coffee.

Probably yes if drunk after 4-5pm. Caffeine half life is around 5 hours; a cup at 6pm leaves roughly half the caffeine still in your system at 11pm. For evening drinking, switch to Yorkshire Decaf or Bedtime Brew.
