I think a better model would be beer paired with a catalog/website that gives rewards in the form of more beer.
An ad needs to be worth more than the advertising value of the packaging itself, and even very niche beers would not likely be seen by more than a handful of people so at $10 CPM wouldn't fetch more than a dime a bottle. Additionally, there would be the personell cost of filling ad inventory and frequently redesigning the bottle.
