Canonical: https://teas.co.uk/wiki/tea-brewing-temperature/\nIf you fix only one thing about how you make tea, make it water temperature, because it is the single most consequential brewing variable and the one most people get wrong. The headline is blunt: pouring fully boiling water onto delicate teas is the most common reason people think they dislike green, white or fine oolong tea, when in fact they have only ever tasted those teas scalded.\nLast reviewed by the teas.co.uk team in May 2026.\nWhy temperature matters so much\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Why temperature matters so much , Tea Brewing Temperature: The Master Dial. Canonical: https://teas.co.uk/wiki/tea-brewing-temperature/\nHotter water extracts faster and pulls more of everything, including the bitter, astringent compounds (catechins and, with over-extraction, a harsh tannic edge) that ruin delicate teas. Robust, fully oxidised or roasted teas have the structure to take very hot water and actually need it to give their body; delicate, lightly processed teas do not, and boiling water strips out their sweetness and aroma while forcing out bitterness. Temperature is essentially a control dial for the balance between a tea's pleasant and harsh compounds, which is why it matters more than almost anything else.\nThe type-by-type guide\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for The type-by-type guide , Tea Brewing Temperature: The Master Dial. Canonical: https://teas.co.uk/wiki/tea-brewing-temperature/\nApproximate but reliable. Black tea (robust, breakfast, most CTC): a full 95 to 100C. Roasted or heavily oxidised oolong, pu-erh, aged dark tea: 95 to 100C. Lightly oxidised oolong: around 85 to 95C. Most green tea: 75 to 85C. Delicate Japanese greens (sencha) and fine Chinese greens: around 70 to 80C. Gyokuro: unusually cool, 50 to 60C. White tea: 80 to 90C (cooler for delicate Silver Needle). Yellow tea: 75 to 85C. Herbal and fruit tisanes: full boiling, 100C, because there is no tea leaf to scald and the botanicals need the heat. The pattern is simple: the more delicate and less processed, the cooler.\nHow to do it without a thermometer\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for How to do it without a thermometer , Tea Brewing Temperature: The Master Dial. Canonical: https://teas.co.uk/wiki/tea-brewing-temperature/\nYou do not need a gadget. Boiling water is 100C; if you let a just-boiled kettle stand with the lid off, it falls roughly 10C every minute or so in a normal room, so about 80C is roughly five minutes off the boil and 90C a couple of minutes. Alternatively, boil and then add a splash of room-temperature water to a delicate-tea pot to knock the heat down. A variable-temperature kettle removes the guesswork and is the one piece of tea kit that genuinely earns its cost, but the standing-and-cooling method is free and works.\nThe nuance\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for The nuance , Tea Brewing Temperature: The Master Dial. Canonical: https://teas.co.uk/wiki/tea-brewing-temperature/\nTwo fair caveats keep this accurate. First, temperature works together with time and leaf quantity: slightly too-hot water with a very short steep can still give a decent cup, which is why some people brew delicate teas hot but fast. Second, these are starting points, not laws; tea, taste and water vary, so the real skill is tasting and adjusting. But the core frankness stands: when in doubt with any lightly processed tea, cooler is safer than hotter, and \"use boiling water for everything\" is the single most damaging piece of common tea advice.\nDoes temperature change the health story\nMarginally, and not usefully. Hotter water extracts more polyphenols and caffeine faster, so a near-boiling long brew is somewhat stronger, but every cup, brewed well or badly, is still ordinary true tea: caffeine, polyphenols, hydration, no miracle. One genuine, separate safety note unrelated to flavour: very hot drinks of any kind are best allowed to cool slightly before drinking, which is general sense, not a tea-specific claim. The reason to master temperature is flavour.\nTemperature by tea type \nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent.

Let the kettle stand a few minutes, or add a splash of cold, so delicate leaf gets roughly 70 to 85C while robust black and tisanes keep the full boil they actually need. Everything else, time, leaf quantity, re-steeping, is refinement on top of getting that one dial right, and it costs nothing, the recurring theme of the common tea brewing mistakes guide. A leaf worth the care is in the loose leaf range or the full tea shop.\nReference noted\n\nEFSA Scientific Opinion on the Safety of Caffeine (2015)\n\nFrom the curatorteas \u00b7 Freshness beats provenance for most drinkers.
