Simplify your brew day with the Large Grain Drawstring Mesh Bag. Specifically designed for the "Brew In A Bag" (BIAB) method, this massive 31.5" x 21.7" bag acts as a liner for your kettle, replacing the need for a separate mash tun and false bottom. Constructed from high-strength, food-grade polyester mesh, it allows for high-flow recirculation and excellent wort drainage while containing even the finest grain particles. Featuring a heavy-duty drawstring and reinforced seams to handle the weight of up to 25+ lbs of wet grain.
