From the labelLabel states 'Ale with Lime Juice and Lime Puree' — a sour ale with citrus fruit adjuncts. The style descriptor 'Sour' in the beer name combined with lime-forward copy indicates a fruited sour. The TTB class 906 (Malt Beverage Specialties - Flavored) and 5.5% ABV are consistent with a gose or fruited sour. Gose is the most likely classification given the lime/citrus focus and sour designation, though the label does not explicitly state 'gose' or 'kettle sour.' Confidence capped at 0.75 due to reliance on copy inference rather than explicit style naming.
