Culture Brewing Co. uses Clarity Ferm, a brand of the AN-PEP (Aspergillus niger prolyl endopeptidase) enzyme. It is added during fermentation, where it cuts gluten proteins at proline sites. Brewers typically adopt it to prevent chill haze rather than to reduce gluten.
Prefer a sealed bottle or can. Shared tap lines can carry residue from other beers poured through them, which can reintroduce gluten regardless of how the beer itself was brewed.

Recipes and processes change without notice, and enzyme use can vary between batches; we cannot guarantee this beer is currently gluten-reduced. Confirm directly with the brewery before consuming. Enzyme-reduced beer is not gluten-free. Nothing here is medical advice.
