Canonical: https://teas.co.uk/wiki/cold-brew/\nLast reviewed by the teas.co.uk team in February 2026.\nCold brew tea is the overnight method that produces a smoother, less bitter, sometimes higher antioxidant cup than hot brewing. Method: tea bags or loose leaves in cold water, fridge 4-12 hours, strain, drink. No heat, no fuss, no acrid notes. Works with any tea, transforms green tea, and is the secret to good iced tea at home. Why cold brewing works \n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Why cold brewing works, Cold Brew Tea. Canonical: https://teas.co.uk/wiki/cold-brew/\nHot water extracts everything, caffeine, aromatic compounds, amino acids, AND tannins (the bitter astringent compounds). Cold water extracts caffeine and aromatic compounds quickly but extracts tannins much more slowly. Result: a cup with the flavour layers but without the bitter edges.\nSpecifically:\n Tannins are reduced 60-80% compared to hot brewed equivalent. The cup tastes smoother, less astringent. Caffeine extraction is moderate. Cold brew typically delivers 60-80% of hot brew caffeine, still meaningful, slightly gentler. Catechins (in green tea) are preserved better. Some research suggests cold brewing produces higher catechin retention than hot brewing. Aromatic complexity is preserved. Heat volatilises and damages some aromatic compounds; cold brewing keeps them intact.\n The basic cold brew method \n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for The basic cold brew method, Cold Brew Tea. Canonical: https://teas.co.uk/wiki/cold-brew/ Standard recipe (1 litre) \n 4 tea bags (or 4 tsp loose leaf) in a 1-litre jug or jar with a lid. Fill with 1 litre cold filtered water.

Note: theoretical concern about bacterial growth at warmer than fridge temperatures over long periods. Refrigerator cold brew is safer. Iced tea (the British/American way)\nBrew tea hot at double strength, pour over ice. The dilution from melting ice brings it to drinking strength. Faster than cold brew, slightly more bitter. The American sweet tea approach. Flash chilled cold brew\nHot brew tea normally, then immediately pour over ice to cool rapidly.
