So, you can distill anything that contains alcohol. Do it to wine, you get brandy. Do it to cider, calvados.
OK, so what about beer?
Hmm, not really thought about it before. And this search engine stuff, fun:
Whiskey is distilled fermented malted grain. So basically beer without the hops addition.
Suppose so, really. Whiskey is distilled ale. Discuss.
Whiskey is famously made by distilling beer, but any distiller will tell you that the “beer” that goes into the still bears little resemblance to the commercial stuff you sip on game day. While it won’t kill ya, those who drink the fermented wash before it is distilled hold little respect in the eyes of the distilling community.
The answer, it appears, is yes.
