Questions people ask
Is Stay Chill gluten free?
No. Stay Chill by Black Plague Brewing is gluten-reduced, not gluten-free. It is brewed from gluten-containing grain and treated with the Clarity Ferm enzyme, which breaks gluten proteins into fragments. Reported testing: Less than 20 ppm. Under US TTB rules a beer brewed from barley cannot be labelled gluten-free, and enzyme-reduced beer is not considered safe for people with celiac disease.
Can I drink Stay Chill if I have celiac disease?
No. Stay Chill is gluten-reduced, not gluten-free, and enzyme-treated beer is not considered safe for people with celiac disease. Even trace and fragmented gluten can trigger an immune response. Choose a beer brewed from naturally gluten-free grains instead, and speak to your doctor.
What enzyme is used in Stay Chill?
Black Plague Brewing 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 Stay Chill?
Reported testing for Stay Chill: Less than 20 ppm. Test method: Independent lab tested before packaging. Treat reported ppm as indicative rather than definitive — the standard R5 ELISA test can under-read the gluten fragments an enzyme produces.
Should I order Stay Chill on draft?
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.
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.
