    "excerpt": "What the water companies say about hard and soft water in each UK region, and the teas blended for each, led by Yorkshire Tea Hard Water.",
    "content_text": "Hard water tea, in short: Hard water makes tea taste darker and can leave a film on top. If your region's water is hard, start with Yorkshire Tea Hard Water, which its maker blends for mineral rich tap water. In soft water areas a soft water blend such as Scottish Blend is the better match.\nIn a hard water area the simplest fix is a tea blended for it, and Yorkshire Tea Hard Water is the one we stock. Whether you need it depends on where you live, so the table below sets out what each water company says about its own region.\nLast reviewed by the teas.co.uk team in November 2026.\nWhat hard water does to a cup of tea\nHardness is dissolved calcium and magnesium, and the Drinking Water Inspectorate says the level depends on local geology. Yorkshire Tea's buyers say hard water makes tea taste darker and thicker, while soft water brings out lightness and briskness.\nThen there is the film. Anglian Water explains that limescale reacts with the natural tannins in tea to make an oily brown scum on the surface. We look at it more closely in what is the scum on my tea and in hard water against soft water.\nThe Inspectorate gives these bands, measured in milligrams per litre as calcium carbonate: soft up to 100, slightly hard 100 to 150, moderately hard 150 to 200, hard 200 to 300, and very hard above 300.\nHard and soft water by UK region\n\nRegionWhat the water company saysSource\nLondon and the Thames ValleyAll the water in the region is hardThames Water\nEast of EnglandThe water in the region is classed as hard to very hardAnglian Water\nYorkshireHard water mainly in the east, softer water in the westYorkshire Water\nNorth West EnglandMost raw water comes from upland reservoirs and is soft or very soft.

The Inspectorate's advice is to ask your own water company for an accurate figure, and most companies have a postcode checker on their website.\nThe teas to buy for hard water\nYorkshire Tea Hard Water is the direct answer. Taylors of Harrogate describes it as a special blend of Yorkshire Tea, with a few tweaks to the recipe, made for tap water with a high mineral content. It is black tea from Africa and India, in a box of 80 bags. Our page on why the blend exists and who it is for has the detail.\nIf you would sooner stay with a standard blend, choose a fuller one. Yorkshire Tea Gold, which the maker calls its finest blend, and Tetley Extra Strong both give you more tea to work with.\nIf your usual tea tastes different after a house move, check the water before you blame the blend. We cover that worry in has Yorkshire Tea changed its recipe.\n\nSoft water: the opposite case\nSoft water has blends of its own. The maker of PG Tips Scottish Blend says it is blended to complement soft Scottish water, and the Glengettie brand has described its Welsh blend as designed for the soft water of its region. Our Scottish Blend page has more, and both teas are in the block below.\n\nKettle and brewing fixes\nYou can also change the method. Anglian Water's own tips for a better looking cup in hard water are:\n\nput a wire scale collector in the kettle\nmake tea in a pot instead of a mug\nuse tea leaves instead of tea bags\ndo not let the tea stew\nuse a tea strainer\n\nThames Water adds one more: empty the kettle when it is not in use. If you want to change the water itself, read filtered water for tea and is bottled water better for tea. For the pot and leaf route, the loose leaf shelf is the place to start.\nHard water tea at a glance\n\nYour waterTea to try firstAlso\nHard or very hardYorkshire Tea Hard WaterYorkshire Tea Gold, Tetley Extra Strong\nSoftPG Tips Scottish BlendGlengettie Welsh Breakfast Tea\nNot sureCheck your postcode with your water companyStandard Yorkshire Tea in the meantime\n\nCommon questions\nHow do I find out if my water is hard?\nUse the postcode checker on your water company's website, or ring them. Limescale in the kettle is the everyday sign.\nCan I use Yorkshire Tea Hard Water in a soft water area?\nYou can, but it is blended for mineral rich water. In soft water the standard Yorkshire Tea is the one to buy.\nIs the film on top the fault of the tea?\nNo. Anglian Water puts it down to limescale reacting with the tannins in tea, so it follows the water, not the brand. A pot and a strainer keep most of it out of the cup.\n\nReference noted\nRegional statements were opened on 13 November 2026 at the Drinking Water Inspectorate, Thames Water, Anglian Water, Yorkshire Water, United Utilities, Scottish Water, Welsh Water and NI Water. Blend statements come from Yorkshire Tea: Hard Water, Yorkshire Tea: black tea range, the maker's product text for Scottish Blend at Morrisons and Wikipedia: Glengettie.\nMore from the tea wiki\n\nRegional Teas of Britain and Ireland: A Buying Guide\nWhy Does My Tea Have a Film on Top\nPG Tips Scottish Blend\nWhat Is the Scum on My Tea?
