Bitter Lemon is a carbonated lemon soft drink with bright citrus acidity, light sweetness, and a dry bitter edge. In cocktails it adds volume, bubbles, and a more grown-up lemon profile than ordinary lemon-lime soda. The bitterness makes a drink feel drier and can help balance recipes with juice or syrup. But if a recipe already contains bitters, bitter lemon can push the drink too dry. Add bitter lemon cold and close to service. Like other carbonated drinks, it should not be shaken; a gentle stir in the glass is enough.
