Diacetyl is associated with which flavor?

• A. Sour
• B. Spicy
• C. Butterscotch
• D. Malty

Answer: (C)

Diacetyl creates a buttery, dairy-like flavor that often carries a sweet, caramel-like edge. In tasting notes, this buttery character is frequently described as reminiscent of butterscotch, which is why diacetyl is associated with that flavor profile. It’s not about sour acidity or spicy heat or simple malt sweetness—the distinctive, creamy butteriness of diacetyl stands apart and line-ups with butterscotch. In practice, brewers and winemakers sometimes manage diacetyl levels through fermentation steps so the yeast can reabsorb it if needed, underscoring that this compound is all about that buttery, dessert-like note.
