Lapsang Souchong is, underneath the smoke, a fully oxidised black tea from the Camellia sinensis plant. That means it shares the well-studied benefits of every other black tea — and a couple of quirks that come with the pinewood drying.
What it brings to the cup
- Polyphenols and theaflavins — antioxidants linked in studies to heart and metabolic health
- L-theanine — an amino acid that produces calm, focused alertness alongside caffeine
- Moderate caffeine — roughly 40–60 mg per 250 ml cup, less than coffee
- Zero calories when drunk black — no sugar, no fat, no carbs
- Hydration — yes, tea counts toward daily fluid intake despite the old myth
A sensible word on the smoke
Naturally smoked foods contain trace polycyclic aromatic hydrocarbons (PAHs). Reputable producers test for these and stay well within UK food safety limits. For a daily drinker brewing a cup or two, the levels are not a concern. If you drink several pots a day, alternate with an unsmoked black tea — your palate will thank you anyway.
Who should go easy
Pregnant or breastfeeding drinkers should keep total caffeine under 200 mg a day — about three cups. Anyone on blood-thinning medication should mention regular black-tea drinking to their GP, as the vitamin K content can interact subtly. Otherwise, enjoy.
