decoction process
Học thuậtThân thiện
Definition
Noun: 1. A specific mashing technique in brewing: A process where a portion of the mash (a mixture of crushed grains and hot water) is transferred to a separate vessel, boiled, and then returned to the main mash tun. This step is repeated to raise the mash temperature through distinct rests, aiding in starch conversion and enzyme activity.
Usage
The decoction process is a traditional method, primarily used in brewing certain beer styles like German lagers, to develop specific malt characteristics. - The brewer used a decoction process to achieve a richer, more complex malt flavor in the bock beer. - While time-consuming, the decoction process can enhance the beer's color and body.
Advanced Usage
- Triple decoction: A lengthy version of the process involving three separate decoction steps, historically used for very pale malts.
- Single decoction: A simplified version using only one decoction step to reach the saccharification temperature.
Variants and Related Words
- Decoction mashing (n): A synonymous term for the decoction process.
- Decoction (n): The act of boiling a substance, especially plant material, to extract its essence. In brewing, it refers specifically to the boiled portion of the mash.
- Infusion mashing (n): A simpler, more common mashing technique where hot water is added directly to adjust temperature, contrasting with the decoction process.
Synonyms
- Decoction mashing
- Step mashing (via decoction): This specifies the step-wise temperature increases are achieved through decoction.
Related Terms and Concepts
- Mash-out: The final step of raising the mash temperature to halt enzyme activity, which can be achieved via a decoction.
- Maillard reaction: Chemical reactions during the boiling phase of the decoction process that contribute to color and flavor development.
Noun
- (brewing) a process in which part of the mash is removed and boiled and then returned
