It's 40%. The number of the proof is twice that of the percentage. Oh, did you know how the "proof" system was invented? What they used to do was make a small pile of black powder, and soak it with the liquor. The alcohol concentration at which a match would ignite the powder was designated "100 proof," which turned out to be around 50%.

40% 1 proof=.5%, so therefore, 80 proof=40%

By convention, "proof" = 2x actual percent alcohol.
That is, 100 percent ethanol is "200 proof"
so 80 proof is 40%

Southern convenience alllll the freaking way! right here is my reason: a million) drinkability- is going down tender(it does not have that harsh burn like maximum severe alcohol drink so circulate forward and drink at once from the bottle) it is ordinary to combine with Coke, Dr. Pepper, and maximum dark soda. 2) severe alcohol content fabric so which you will get below the impact of alcohol quickly 3) because of the fact it is fairly ordinary to drink, females love that s*** so circulate forward and get a effective large cope with of So-Co(that's what each and every of the cool young ones in college call it presently) you could no longer lose!
