Wine Please!

They will never implement such a feature in the game because it would result in a major reclassification of the game in many countries who have censorship restrictions on media depicting consumption of alcohol - FFXIV's current classification in most countries is the equivelant of 'mid teens' and such an inclusion would result in it requiring a more adult classification, something SE would not want as it means losing a major share of it's player base. This is the same reason the player cannot smoke despite there being an ashtray furnishing for houses.

They can get away with depicting NPCs drinking alcohol or producing it, but the moment they make it gameplay that changes the as it's 'interactive' and thus 'encourages alcoholism', and requires a tougher more restrictive classification (I don't agree with such censorship, but that's how many countries' governments have responded and their attitude towards it, if you're unhappy with it contact your local government representative and try and get them to change it).
