Updated April 2026.
Low-alcohol is not a TTB beer class. Session is bar English. Some states sell 3.2% by-weight beer — that is a license word, not a national type. Official US Guinness Draught is 4.2% / 12 fl oz / 125 cal. A 12-ounce 5% pour is one drink. Non-alcoholic SKUs unused as a ranking. No 2026 list.
