This category includes still wines, Champagne, Prosecco, Cava, and other sparkling wines that contribute elegance, acidity, and effervescence to cocktails. Sparkling wines are classic lengtheners and celebratory toppers in drinks like the French 75 and Aperol Spritz, while still wines add vinous depth to sangrias and wine-based punches. Their natural acidity and fruit character make them both sophisticated mixers and standalone highlights in low-ABV cocktails.
