Gluten Reducer, or AN-PEP, is a proline-specific peptidase enzyme that degrades proline-rich, haze-forming peptides and proteins during beer fermentation. It is widely used in commercial brewing, and according to the manufacturer, 80% of commercial breweries in the world use AN-PEP to speed up the clarification process and to produce gluten reduced beers. Use 7 drops for gluten reduction.
This enzyme does a good job cutting up gluten proteins in the beer into harmless peptides. It does such a good job chopping up the gluten protein that those who are sensitive to gluten can drink these beers without issue. Those with Celiac disease should still exercise caution when drinking barley and wheat-based beers, even when treated with AN-PEP.
