Definition

1. Noun:
   • A brewing process involving partial boiling: "decoction mashing" refers to a specific method in beer brewing where a portion of the mash (a mixture of crushed grains and hot water) is removed, boiled separately, and then returned to the main mash tun. This process is used to raise the temperature of the mash through distinct steps and can influence the beer's body, color, and flavor profile.

Usage

• Noun:
  • The brewer used decoction mashing to develop a richer malt character in the traditional lager.
  • Decoction mashing is a more time-intensive technique compared to single-infusion mashing.

Advanced Usage

• "To perform a decoction mash": to carry out the process of decoction mashing.
  • The brewery decided to perform a decoction mash for its annual Oktoberfest beer.
• "A double/triple decoction": refers to performing the decoction process two or three times during the mashing procedure, common in some classic European beer styles.
  • This recipe calls for a double decoction to achieve the desired depth of flavor.

Synonyms

• Step mashing (with decoction): A step mashing regimen that utilizes the decoction method to achieve temperature rises. (Note: Not all step mashing uses decoction, but decoction is a form of step mashing).
