Rye is a traditional cereal grain that finds its way into many homebrewer's recipes. It has become a popular ingredient in IPAs, with homebrewer's using it to make fine Rye IPAs. It is also the main ingredient in the traditional Roggenbier, a beer made with rye as the base. Rye is known to have a spicy flavor that goes well in small amounts in many types of beer. It is fully modified and has a small kernel that can get quite sticky when used in large amounts. Rice hulls are recommended when using a large amount of rye in an all-grain recipe.
