How many 750ml bottles of wine are in 4L?

Answer 1

five bottles. You'll also have at least 250ml left over to fill from a sixth bottle, and given that a 750ml wine bottle won't be completely full, you can estimate that actually about half (375ml) the sixth bottle can be poured into the 4l vat or container, given an average of 725ml in a 750m bottle (allowing for corks and margins of error.

Answer 2

5 and 1/3rd bottles of normal sized 750ml bottles of wine.

So 1 liter is 1000ml you have 4000ml/750ml=5.33 bottles of wine.
