It is not part of the official rules of Bridge, but there is a tradition among some players that if the declarer succeeds in making the contract and wins the last trick with the beer card, dummy must buy the declarer a beer. In the same way, if the opponents defeat the contract and one of them wins the last trick with the beer card, the opponent who wins the last trick is bought a beer by the other opponent.
Saw this in a friends house about 15 years ago. I wonder if it is still in production? I remember the card deck had special markings so you could deal out a training hand, play it and then the book would tell you what you should have bid and what the best contract was, and how to play it.
