Is cider gluten-free

Gluten is the collective name for a group of storage proteins found in wheat, barley, rye and their hybrids. In coeliac disease, these proteins trigger an immune response that damages the lining of the small intestine, and the only established management is lifelong avoidance.

Apples and pears contain no such proteins. A cider made by pressing fruit, fermenting the juice and packaging the result has no cereal input at any stage, and no route by which gluten could enter.

This is a genuine structural difference from beer, which is made from malted barley and therefore contains gluten unless it has been specifically produced or treated to remove it. It is the reason cider is often suggested as an option for people avoiding gluten — a suggestion that is broadly right about the category and unreliable about individual products.

Under the Codex Alimentarius standard for foods for special dietary use for persons intolerant to gluten, a food may be described as gluten-free where its gluten content does not exceed 20 milligrams per kilogram. That threshold has been adopted into many national and regional regimes and is the figure behind most gluten-free claims worldwide.

Under Regulation (EU) No 1169/2011, cereals containing gluten are among the substances that must be declared where they are used as an ingredient, and the declaration must be emphasised in the ingredient list. The regulation was retained in modified form in Great Britain after EU exit.

Two important limits follow. First, an allergen declaration covers ingredients rather than cross-contact, and precautionary "may contain" statements are generally voluntary rather than required, so their absence proves nothing about shared lines. Second, the rules on ingredient listing for alcoholic beverages have historically differed from those for other foods and have been subject to ongoing change, so a cider label may carry less ingredient information than a comparable soft drink.

The practical consequence is that a cider without a gluten-free claim is not thereby a cider containing gluten, and a cider without a "may contain" warning is not thereby free of cross-contact risk.

Of a producer: is any barley-derived ingredient used, and is the cider produced, packaged or filled on equipment shared with beer or with any cereal-containing product? Producers answer this routinely and it is the single most informative question available.

Of a bar or pub: is the cider dispensed through a line that has been used for beer? Draught cider in a mixed venue is a cross-contact route that has nothing to do with the cider itself, and the answer often is not known at the bar.

Of a label: does it carry an explicit gluten-free claim under the relevant national scheme, or an accreditation mark from a coeliac organisation? An explicit claim is a regulated statement; an absence of gluten in the ingredients list is a weaker signal.

Where a definitive answer is not available, a definitive answer has not been given, and that is the honest position rather than a cautious one.
