Why it works
Moussaka combines lamb savor, eggplant umami, tomato acidity, and creamy bechamel. Tart medium red works here because its acidity keeps tomato, cheese, and roasted flavors lively while moderate tannin gives just enough grip. The important move is respecting umami so the wine does not taste hollow or metallic, staying in the same weight class as the dish, so the wine supports the food instead of becoming a separate event.
Wine style
