Clausthaler Grapefruit is the grapefruit variant in the Clausthaler alcohol-free range, brewed in Frankfurt. It combines a Clausthaler non-alcoholic beer base with grapefruit juice concentrate, citrus juices, natural grapefruit flavouring, and beta-carotene, which provides the drink's colour. As a non-alcoholic radler-style option, it sits as one of the fruit-forward expressions within the Clausthaler range.
