Boiling water on green tea destroys the cup. Tepid water on black tea makes coloured water. The right temperature for the right tea takes a thermometer or a phone timer trick, and once you know it, every cup gets noticeably better.

The \"right\" temperature for each tea is the one that brings out the desired balance.\n Black tea: 95-100\u00b0C. Black tea has been fully oxidised, the catechins have already converted to theaflavins/thearubigins, which extract well at boiling. High temperature releases the malt and body that make a strong cup. Below 90\u00b0C the cup is thin. Green tea: 75-80\u00b0C. Catechins (notably EGCG) are bitter when over extracted. At 80\u00b0C they emerge in balance with the amino acids; above 85\u00b0C they dominate and the cup turns harsh. Water above 90\u00b0C is the single biggest reason most UK drinkers think they \"don't like\" green tea. White tea: 80-85\u00b0C. Delicate; high heat scalds the buds and produces a flat cup. Slightly higher than green because white needs longer steeping. Darjeeling first flush: 85-90\u00b0C. Lighter and more delicate than other blacks; full boiling is overkill and over extracts. Second flush Darjeeling can take 95\u00b0C. Oolong: 85-95\u00b0C. Wide range because oolong itself spans light (close to green) to dark (close to black). Light oolongs at 85\u00b0C; dark roasted oolongs at 95\u00b0C. Pu erh: 95-100\u00b0C, rinse first. The first 30-second steep is poured away (\"rinsing the leaves\") to remove dust and wake up the leaf. Subsequent infusions hot. Rooibos and herbal: 95-100\u00b0C, long steep. Caffeine free, no over extraction worry. Long steep (5-8 min) brings out the volatile oils.\n How to hit the right temperature without a thermometer \n\nSource: Teas.co.uk.

Or boil and pour into a cold cup, leave another 30 seconds, then add the leaf. For 85\u00b0C white/Darjeeling first flush: Boil and leave 60 seconds, then pour. For 95\u00b0C black/herbal: Pour straight from the kettle the moment it clicks off, into a pre warmed cup. (Pre warming keeps the temperature in range during the brew.)\n\nA \u00a315 variable temperature kettle from Argos pays back in under a year if you drink mixed teas.

For black tea this is fine; for green tea it accidentally helps you hit 80\u00b0C. For black tea brewed in a cold mug, the water is at 85\u00b0C by the time the bag has bloomed, under extracted. Pre warm the mug with a splash of hot water poured out before brewing. The cup is noticeably better. Soft water vs hard water\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Soft water vs hard water, Best Water Temperature for Tea. Canonical: https://teas.co.uk/wiki/best-water-temperature-for-tea-the-thermometer-guide/\nUK water hardness varies massively by region. London, the South East, and Cambridge have hard water (high calcium); Scotland, Wales, and the North West have soft. Hard water flattens delicate teas (green, white, Darjeeling) and over extracts strong blacks. Soft water makes everything brighter. More on water hardness and tea. Filtered water (a Brita style jug) closes most of the gap. FAQ\nShould you boil water for tea? Depends on tea. Black, herbal, rooibos, chai: yes (95-100\u00b0C). Green and matcha: no (75-80\u00b0C). White and Darjeeling first flush: between (80-85\u00b0C).\nWhy does my green tea taste bitter? Almost certainly water too hot or steeped too long. Try 80\u00b0C for 90 seconds.\nDoes water temperature affect caffeine? Slightly, caffeine extracts faster at higher temperatures, but most caffeine is out within the first 30 seconds at any temperature. Brew time matters more than temperature for caffeine content.\nIs filtered water better for tea? Yes, especially in hard water regions. Removes excess calcium that flattens the cup. Brita style jug is enough. Curator's note: a \u00a315 variable temperature kettle is the single best tea related purchase you can make. The 80\u00b0C button transforms green and white tea drinking. The 95\u00b0C button is also more accurate than \"let it stand 10 seconds\" guesswork. Lee, Teas.co.uk, Tunbridge Wells. Quick take\n\nSource: Teas.co.uk.

Boiling (95 to 100C) for black, rooibos, herbal and chai; 75 to 80C for green and matcha; 80 to 85C for white and first flush Darjeeling. Below 90C a black cup is thin; above 85C a green cup is bitter. Caffeine extracts fast at any heat, so steep time, not temperature, controls strength. No thermometer needed, a timed wait, a pre warmed mug and a filter jug get you most of the way, and a variable temperature kettle gets you the rest. \nBrew it right: a robust black from Yorkshire Tea, whole leaf green from Teapigs, or matcha from Pukka.
