Mashing is what turns regular malted barley into the wort that ultimately becomes beer. And as with most other aspects of homebrewing, there are as many ways to mash as there are brewers.
If you keg your homebrew, you probably use repurposed soda kegs (a.k.a. Corny kegs).
Homebrewers today enjoy a wider selection of malts than ever -- so wide, in fact, that it’s easy to become overwhelmed.
