The Boilermaker House Sour bridges the gap between cocktail bar and brewery, layering smoky blended scotch against the citrus punch of a classic sour before finishing with a crown of hoppy IPA. The egg white creates a dense, creamy foam that carries bitters aromatics to the nose, while passionfruit adds a subtle tropical sweetness that tempers the whisky's peat. It's a textural experience as much as a flavor one—the silky body giving way to the beer's effervescence and bitter edge.
