Decaf Tea UK, every decaffeinated blend, every brand.

No, decaffeination removes 95-99% of the caffeine, leaving 2-5mg per 200ml cup compared to 40-55mg in the caffeinated version. For comparison, a cup of coffee is 80-100mg. Decaf is not zero, but it is well below the threshold most caffeine-sensitive drinkers can detect.

Three methods are used commercially: CO2 (the cleanest, expensive, used by premium brands), water-process (no chemicals, slightly more flavour loss), and ethyl-acetate (a naturally-occurring solvent, sometimes flagged as "natural decaf"). All three are food-safe. CO2 generally produces the best-tasting cup.

Yorkshire Tea Decaf (closest to standard Yorkshire), Twinings Earl Grey Decaf (the only widely-available decaf Earl Grey), and Clipper Organic Decaf (organic, ethical sourcing) are all reliable. We stock all three plus several others.

Yes, UK NHS guidelines say up to 200mg caffeine per day is safe in pregnancy, and a cup of decaf tea is 2-5mg, well within the limit. Several cups per day pose no problem. If avoiding caffeine entirely, switch to caffeine-free herbals (chamomile, rooibos, peppermint).

Slightly. The decaffeination process strips a small amount of flavour along with the caffeine. Most drinkers cannot tell side-by-side, but very sensitive palates notice that decaf tastes a fraction lighter or less brisk. Brewing for an extra 30 seconds usually closes the gap.
