Was just doing a search to find out the capacity of a Jeroboam of champagne and found this very informative diagram showing the nomenclature of each different champagne bottle size.
I'm reluctant to say " Every time…", but, every fucking time…
As an FYI, still having a foreskin and having only knowingly met one person of the faith in question, my knowledge is sparse and had to DDG the etymology of the bottle names.
