Decoction
Decoction is a traditional brewing method where part of the mash (the mixture of grains and water) is removed, boiled separately, and then returned to the main mix. Think of it like making tea, but instead of just steeping once, you take some of the mixture out, heat it up more, and put it back in. Brewers use this technique to get different flavors and characteristics in their beer, especially in traditional European-style beers. While not all breweries use this method today, it's still important in craft brewing and is often mentioned when describing traditional brewing processes.
