The answer starts with the water, because a cup of tea is almost entirely water and only a sliver of dissolved leaf.

Canonical: https://teas.co.uk/wiki/best-water-for-tea/The best water for tea is fresh, low to moderate hardness, low in chlorine, and freshly drawn and boiled once. It does not have to be bottled or special; for most homes a simple filter jug delivers exactly this. The goal is clean and gentle, not pure, see distilled water and tea for why pure is wrong.\nWhy not just any tap water\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent.

Canonical: https://teas.co.uk/wiki/best-water-for-tea/Tap water is safe but variable: hardness, chlorine and freshness change the cup dramatically, see tap water for tea. In hard water areas it mutes flavour and films the surface; chlorine adds a faint pool note tea amplifies.

UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Why water changes the cup, The Best Water for Tea (A Practical Guide). Canonical: https://teas.co.uk/wiki/best-water-for-tea/A cup of tea is, by weight, 98 to 99 per cent water and only one or two per cent dissolved leaf, so the water is most of the recipe, not a detail. Hardness is the biggest lever: the dissolved calcium and magnesium common across much of the south and east push the brew slightly alkaline, where tea polyphenols oxidise and bind with calcium, the single reaction behind both the dull surface film and the flat, muted taste of hard water tea. Very soft water swings the other way and can over extract a strong black into something thin or sharp. Chlorine adds a faint swimming pool note that a filter or even a short rest of the water removes, and water boiled fresh once tastes livelier than water reboiled flat, which has lost its dissolved oxygen. Distilled or zero mineral water is the opposite mistake: with nothing dissolved to take part, extraction goes thin and unbalanced, harsh and hollow at once. Between those failure modes sits a broad, forgiving middle, a modest, gentle mineral content near neutral, and a simple filter jug moves ordinary tap water toward exactly that, knocking back chlorine and the harshness causing carbonate without stripping the water bare. That is why the cheap fix beats every expensive alternative.\nWater for tea, at a glance \nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent.
