how do i find out the bottle sizes required for different countries? Is there a specific resource out there ?
I would be interested in an official resource for the EU. From past experiences with Tequila/Mezcal, 700ml is only really more tightly enforced in Germany and the UK. Other EU countries like Belgium, Holland, Italy, France, Spain use both 700 and 750ml, but distribution is more limited if you only have 750ml bottle.
