It is largely a brewing variable you control, see the temperature guide and water.\nBy tea typeBrisk Assam and strong Ceylon are deliberately astringent; fine green and white are low; well made oolong balances it.

Canonical: https://teas.co.uk/wiki/astringency-in-tea/\nIs astringency the same as bitterness? No. Bitterness is a taste; astringency is a drying feel from tannins binding saliva proteins. A tea can have one without the other.\nIs astringency bad? Not in measure, it is the brisk structure that makes black tea refreshing. Only harsh, gripping astringency from bad brewing is a fault.\nHow do I reduce it? Cooler water, shorter steep, less leaf, softer water, or a splash of milk to bind the tannins. It is largely a brewing lever you control, not a fixed flaw.\nWhy does milk help? Milk proteins bind the tannins, softening astringency, which is why robust black takes milk well and delicate tea does not need it.\nQuick take\n\nSource: Teas.co.uk.

Canonical: https://teas.co.uk/wiki/astringency-in-tea/Astringency is a drying texture from tannin, distinct from bitterness, desirable as briskness in measure and a brewing fault in excess. Naming it correctly sharpens both tasting and technique. Browse a brisk black tea, a malty Assam or the wider loose leaf range at teas.co.uk, or the full tea shop. Buy on the cup and the description, check the per cup price, and free UK delivery is over \u00a335.\nFrom the curatorteas \u00b7 The infusion is more important than the shop.
