Oat Hulls – Gladfield

Oat Hulls are the outer shell layer of the oat, inedible and normally removed from the oat, when used for brewing the hulls improve the filter bed of the mash to decrease the likelihood of a stuck mash.

Oat hulls are non-fermentable, and provide bulk helping prevent the mash from settling and becoming stuck during the sparge. Hulls are generally used when making wheat or rye beers.

Helpful with wheat-heavy mashes

Oat hulls help form a filter bed when a recipe uses a high proportion of huskless Gladfield Wheat Malt. Gladfield also suggests adding a few hulls as the proportion of Crystal Wheat Malt rises. The hulls aid lautering; they are not a fermentable grain.
