A $100 bottle of bourbon is equivalent to a $30 bottle of wine in cost per drink (alcohol equivalent drinks). If you buy a 100 proof or cask strength then it's more like a $120-$150 bottle of bourbon is equivalent to a $30 bottle of wine.
And who hasn't bought a $30 wine (or more).
I recently bought a bottle of bourbon for $225 - That's really only like drinking a $65 wine bottle.
And if you think about the myriad great $30-$60 bottles of bourbon, that's really like buying wine for $10-$20 a bottle.
Tell that to the spouse if you have to justify why you spent so much.
