Not sure what the official stance is on the drinking age but Emerald has been drunk once already and she's 16. Whether that was legal or not I have no idea. :D
The legal drinking age is 16 in Morocco.
And it was 16 until 2009 in France. Most countries though really have a "this is the legal age for you to purchase alcohol" but allow alcohol to be legally consumed under that. It's legal to consume alcohol in private for Frenchies. England has it at the age of 5 when not on licensed premises. Australia just requires parental consent if you're under 18 (and I've taken advantage of that only once - not really my schtick tbh).
And given that the average life expectancy for Huntsman is likely to be low due to their line of work, and the general hellworld everybody lives in where any negative emotion can easily lead to destruction, the cultural background of Remnant would be incredibly different, and would have different laws in regards to such things.
