Many have asked which size is best for wine ..
A typical wine bottle size is 750 ml which contains 25.4 fluid ounces
Growler & Hydration Bottles
The one bottle theory 32oz is best - it will give you a little extra room to mix some fruit and make it a Sangria
The two bottle theory is tricky because you really have 3 solid choices
1. Get a 64oz and you'll have room for fruit to make Sangria or add anything else you enjoy in your wine
2. Get a 40oz and you'll have 15.4 ounces left to fill a 20oz Tumbler for drinking right away
3. Get a 32oz and an 18oz and you've got it all in there with just a sip left before you close it up
