Question: how many beers is equivalent to a bottle of vodka?
Answer: Assuming the beer to be a slightly heavier-than-average 6% ABV in 355 ml serving sizes (eg, US cans), and the vodka to be a 750 ml bottle at 40% ABV, the vodka would have more alcohol in it. Doing the math: You've got 355*12=4260 ml of beer.
