Watermelon Marg

From the label“Label explicitly states 'Sour ale brewed with oats and milk sugar, conditioned on watermelon and lime Italian ice' — a kettle sour with fruit (watermelon) added, fitting fruited_sour. The product name 'Watermelon Marg' and descriptive copy confirm fruit-forward sour identity. TTB class 906 (flavored malt beverage specialty) supports specialty classification. This is a keg collar (15.5 US gallons = 58,673 ml). Brewed & packaged at SNAFU Brewing Company, North Charleston, SC — no geography conflict or 'for' language, so producer_relationship is 'self'.”
