Vault City Brewing in Edinburgh specialises in modern sour beers loaded with fresh fruit. Gosebumps: Lemon & (S)lime is a mixed fermentation sour built on fresh lime, lemon juice and zest. This vegan-friendly beer is unapologetically tart and bracing—not for the faint of heart.

The lime and lemon combination delivers a sharp, acidic character that cuts across the palate. At 4.2% ABV, it packs serious citrus punch in a lean, refreshing package.
