It’s really not though. The standard understanding is that a 750ml bottle consists of five 150ml (or 5oz) glasses of wine. Calling that amount a “glass” perhaps is unfortunate, but it is convenient and well understood by most. But then again, I’ve also never known anyone who claimed that their 375ml pours were a “glass”. That just strikes me more as ignorance.
