eli5 : What is alcohol proof and the difference between alcohol with high and low proof

Answer 1

Proof is just a way to say “how much actual alcohol % is this liquid”

“2 Proof” = 1% Alcohol.

So a 100 proof bourbon would have 50% alcohol by volume. A 70 proof vodka has 35%. A moonshine could be 150 proof or higher.
