The Malting Process

Malting is a process in which grains are allowed to germinate and then quickly dried in a kiln before the plant has a chance to fully develop. The malting process develops enzymes that are required to modify complex starches in the grain into simple fermentable sugars during a later step in the brewing process called mashing.

Steps in the Malting Process

  • Raw grains are soaked to begin germination.
  • Moisture and germination is maintained until the green 'acrospire reaches a length approximately the size of the grain. This takes approximately 5 days.
  • Green malt is kiln dried until the level of moisture is reduced to about 6%.
  • The brittle acrospires are separated from the grains, and the grains are packaged for shipping.
