Enzymes in Beer: What’s Happening In the Mash

Enzymes in Beer

As homebrewers, we’re usually never satisfied until we know how things work. We constantly ask why and how something is done until we understand the basic concept. When you start brewing all-grain, you hit a certain temperature to hit a specific characteristic because you were told to do so. You start picking up on words like alpha-amylase, beta-amylase, mash out and protein rest, and now you’re more curious than ever about what’s going on in the mash.

Here we’ll discuss the enzymes in beer, which convert the starch in malt into soluble sugars. By understanding and making enzymes work for you, an all-grain brewer can control a multitude of components in their beer.

  • Aroma
  • Flavor
  • Body
  • Overall mouthfeel
  • Attenuation
  • Color
  • Alcohol content
