    "content_text": "Plain tea \u2014 black, green, white, oolong, pu-erh \u2014 contains none of the 14 regulated allergens. Neither does plain rooibos, peppermint or chamomile. The questions start when a product stops being one ingredient.\r\nUK rules require the 14 major allergens to be emphasised in the ingredients list, usually in bold, whenever they are deliberately used. GOV.UK: ingredients list \u00b7 Food allergy advice for consumers\r\nWhere allergens turn up in tea\r\n\r\n\r\n\r\nAllergen\r\nWhere you might find it\r\n\r\n\r\n\r\n\r\nMilk\r\nChai latte powders, matcha latte mixes, instant tea drinks, some \"creamy\" flavoured blends\r\n\r\n\r\nCereals containing gluten\r\nBarley tea (mugicha), blends with barley or oats, some genmaicha-style products with added cereal\r\n\r\n\r\nNuts\r\nAlmond, pistachio or marzipan-flavoured blends, and \"may contain\" warnings from shared lines\r\n\r\n\r\nSoya\r\nLecithin in chocolate pieces in chocolate teas, and in some latte powders\r\n\r\n\r\nSulphur dioxide / sulphites\r\nDried fruit pieces in fruit blends (apple, papaya, pineapple)\r\n\r\n\r\nSesame, celery, mustard\r\nRare, but possible in savoury or spiced blends\r\n\r\n\r\n\r\nTwo that surprise people: barley tea is not gluten-free, and dried fruit in a fruit blend may be sulphited.\r\n\"May contain\" is a different statement\r\nAn emphasised ingredient means it is deliberately in the recipe. A \"may contain\" or \"made in a factory that also handles\" line is voluntary precautionary labelling about cross-contamination risk in the factory. It is not a promise that the allergen is present, and not a promise that it is absent.\r\nIf you are seriously allergic, treat those warnings as meaningful and ask the manufacturer if you need more detail.\r\n\"Vegan\" does not mean \"free from milk\"\r\nThis one matters. A vegan label describes the recipe, not the risk of cross-contamination with animal-derived allergens during production. A product can be labelled vegan and still carry a \"may contain milk\" warning.\r\nIf you are choosing for a milk allergy rather than a dietary preference, read the allergen information, not the vegan badge.\r\nLoose tea, scoops and caf\u00e9s\r\n\r\nLoose tea sold from a jar or scooped in a shop is not pre-packed in the usual sense, so the allergen information is given in another way: ask staff, who must be able to tell you.\r\nShared scoops and infusers carry blends between jars.\r\nIn a caf\u00e9, say the allergy clearly and ask about the whole drink: the tea, the milk, the syrup, the topping and the equipment. \"No milk\" is not the same as \"no milk anywhere near it\".\r\n\r\nA quick routine before you buy\r\n\r\nCheck the exact product, size and market \u2014 recipes differ between formats and countries.\r\nRead the full ingredients, not the front of the pack.\r\nLook at the emphasised allergens, then any \"may contain\" line.\r\nKeep the box while the tea is in a caddy, or photograph the label.\r\nRe-check when you buy again: recipes change.\r\n\r\nOur herbal and fruit infusions guide covers what is in those blends, and tea for vegans covers the dietary question separately.\r\nIf someone has a reaction, follow their emergency plan and get medical help. This page is general information about labelling, not advice about an individual allergy.\r\nCommon questions\r\nIs tea gluten-free?\r\nPlain tea is. Barley tea is not, and some blends contain barley, oats or malt.\r\nIs there milk in a chai tea bag?\r\nNot usually \u2014 chai bags are tea and spices. Chai latte powders are a different product and often contain milk powder.\r\nDo tea bags themselves contain allergens?\r\nThe filter paper is not an allergen, though some bags contain plastics. That is a separate question \u2014 see plastic in tea bags.\r\nWhat about \"natural flavouring\"?\r\nIt is a flavouring ingredient, and any allergen used in it must still be declared. See what natural flavouring means.",
