Question

How many beers is one shot of 128 proof moonshine?

Answer 1

I would guess around a case or 2

Answer 2

Approximately 1.6 12 oz servings of beer, or about 19 oz of beer.
   There's no official definition of a shot except in Utah where it's defined as 1.5 fl oz. Elsewhere it can be anything from 1.25 fl oz to 1.5 fl oz. For this problem, I'll assume 1.5 fl oz. At 128 proof, that means that the moonshine is 128/2 = 64% alcohol by volume. Also the alcohol content of beer ranges from 3.9% to 5.9%. For this problem, I'll assume 5% is the concentration of been (10 proof) and 12 fl oz. So
 1.5 * 0.64 = 0.96 fl oz for shot
 12 * 0.05 = 0.6 fl oz for beer.
 0.96 / 0.6 = 1.6 beers.
   So there is about 1.6 beers worth of alcohol in that one shot of 128 proof moonshine.
