Guardian Sun is a Grapefruit Hefeweizen. Yep. A Grapefruit Hefeweizen. It was brewed with equal parts German malted wheat and Pilsner malt, and lightly hopped with German Tettnang. After fermentation, we added fresh grapefruit zest and juice to achieve the desired Zest-A-Peel levels of historic, traditionally brewed Grapefruit Hefeweizens.
