I feel compelled to comment on this, being a parent of a 19 year old boy. We have traveled with him to Europe and Asia where there are no legal drinking ages for consumption (not sure what the legal age is for purchase in France). We realize he drinks at least some alcohol when his is with his college buddies. When we are home together, we offer a small amount of whatever we are drinking with dinner (beer or wine) to model good social drinking behavior. We have zero tolerance for drinking and driving (even a small amount) and we have discussions about the difference between social drinking and binge drinking. Every family should examine their own behavior around alcohol, assess their own child and then decide what makes sense. Personally I would never "bring the party home" because that promotes binge drinking, which is extremely dangerous.
