How much residual sugar is in zero-proof drinks, and does it matter for health?

Sugar in zero-proof drinks arrives through two routes: residual sugar from incomplete fermentation (relevant in NA beers and wines), and added sugar used to balance the flavour profile after alcohol removal. The latter is the more significant source in most premium NA products, because dealcoholisation — whether through vacuum distillation, reverse osmosis, or spinning cone technology — tends to strip flavour compounds alongside alcohol, leaving a thin, acidic liquid that manufacturers compensate for with sweetness.

NA wine is the most sugar-variable category. Dealcoholised red wines typically contain 2–6g/100ml of residual sugar (well within the "dry" range for conventional wine). Some NA whites and rosés drift higher to compensate for lost fruit aromatics — up to 10–12g/100ml in some commercial examples. This is still less than most fruit juices (10–12g/100ml) but comparable to a medium-dry conventional wine.

NA spirits are generally very low in sugar when made via botanical distillation (Seedlip, Monday, Everleaf). RTD formats of these same products in cans or mixtures may add tonic or juice, bringing sugar content up significantly — the spirits themselves are fine; the canned format isn't always equivalent.

Kombucha occupies a nuanced position: raw kombucha contains residual unfermented sugar (2–8g/100ml) plus the acids and probiotics from fermentation. Commercial kombucha often has added sugar post-fermentation to back-sweeten, which should be listed separately. The sugar in kombucha comes with fibre, acids, and functional compounds that modulate its glycaemic impact somewhat — though individuals with diabetes or insulin resistance should account for it fully.

Practical guidance: anything under 5g sugar per 250ml serving is genuinely low-sugar. Most premium NA spirits qualify. Sweeter fruit-based mocktail mixers, commercial kombucha, and some NA wines require more attention for those tracking sugar closely.
