decoction mashing

Decoction mashing is a traditional brewing process used to extract flavors and sugars from malted grains. It involves boiling a portion of the mash (the mixture of grains and water) to allow enzymes to break down starches into sugars. This mash is then mixed back into the main mash, raising the overall temperature. This method enhances the beer's aroma and flavor, resulting in a rich, complex profile. Decoction mashing is particularly popular in producing certain styles of beer, like traditional German lagers, offering distinctive characteristics that set them apart from other brewing techniques.
