get maybe 6 bottles of the highest proof whisky you can afford.
The structuring of alcohol taxes is interesting. Alcoholic beverages are not taxed by proof. Instead they are taxed by volume.
Before I really got into local made liquors, I did a price comparison. If you look at alcohol prices by proof, you will often see that lower proof alcohols are more expensive than higher proof alcohols.
750ml of 190 proof everclear is available here in the store for $35. [that is a 95% alcohol solution, it has 712ml of pure alcohol in it].
Compared to 80proof whiskeys you pay a lot more for the alcohol in those.
Plus with most commercial grade whiskeys they have included all of the other 'spirits' [Acetone, Methanol, acetates, Propanols, Butanol, and Amyl alcohol] in it for 'flavor'. It is these other spirits that give you a hangover. If you get a chance to drink pure ethanol with all other spirits removed, you can not get a hangover from it. Because the 'bad' alcohols have been removed.
