I thought the 750ml bottle was a single serving size?

For a joke, my family got me a 750ml glass a couple of Christmases ago. I have yet to use it.

750 ml has nothing to do with how much wine people are expected to drink at once; it's an artifact of glass-blowing. A typical medieval glass-blower's lungs allowed them to create bottles of 700-800 ml with a single long breath.

That's a very cool piece of useless trivia. Thanks.

Is there something about glass blowing which makes it air-inefficient? My vague recollection from my time as a low brass player in college is that the prof's lung capacity measuring apparatus (yes, really) put most of us in the 3-4L range, with one outlier around 5L. Granted, we were trained for such magnificent feats of blowing hot air, but so too must glass blowers be.

It is more about the pulmonary strength needed to start the bubble in sufficent glass for the bottle size.

I'd guess that it's also relates to a pressure that glass blower had to create. Then the total volume would be less than free volume.

Sounds like something you should aspire to :)

I can drink a bottle myself lunch to bed on a weekend, but not every weekend.
