Beer and Wine Hobby offers two styles of single-use muslin bags.
The small muslin bag is great for containing hops in the boil. It measures 5" x 11" unstretched and will hold up to 1 oz of leaf hops, and 2 oz of pellet hops.
The large bag measures 5" x 28" unstretched and is great for steeping grain, spices and hops.
Note: Unless specified, use either large or small muslin bags for Beer and Wine Hobby's fine craft brew recipe kits.
