A fifth of vodka is about the same volume as a standard 750 mL wine bottle, so it’s roughly 1 bottle of wine in size, give or take a little depending on the wine bottle and spirit measurements.

Quick math

  • A fifth of vodka = about 750 mL.
  • A standard bottle of wine = 750 mL.
  • So in terms of volume, 1 fifth of vodka ≈ 1 bottle of wine.

Important difference

That does not mean they have the same alcohol content by drink style. Vodka is much stronger than wine, so a fifth of vodka contains far more alcohol than one wine bottle of typical table wine.

Simple takeaway

If you’re asking about bottle size , the answer is: about one bottle of wine.

If you’re asking about alcohol amount , vodka is much more concentrated than wine.

TL;DR: A fifth of vodka is about the same volume as 1 bottle of wine, but it contains much more alcohol.
