What is light whiskey? Light whiskey is a legal term that was built in the '70s for people who wanted to distill their whiskey straight to proof, generally 80 proof, rather than distilling it to a higher proof and then watering it down to proof. It's lighter. I'm told it's easier drinking. I've literally never seen the stuff. I don't even know who makes it. It's sort of a style that's fallen out of favor. I don't even know if it's actually ever in style, frankly. But the '70s were a weird time. What can I say? So I'm told. Pretty sure I wasn't dead yet. Or alive yet. And that's a quick summary of light whiskey.
