What enzyme is used in All beers (entire lineup)?
Key City Brewery & Eatery 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.
How much gluten is in All beers (entire lineup)?

Gluten claims on this page are independently researched from published sources and community reports — they are not verified by lab testing by Off Label. Recipes and processes change without notice, and enzyme use can vary between batches; we cannot guarantee this beer is currently gluten-reduced. If you have celiac disease or severe gluten sensitivity, confirm directly with the brewery before consuming. Enzyme-reduced beer is not gluten-free. Nothing here is medical advice.
