What would a wine game be without a judge? There needs to be someone who steps in to select a fine bottle of wine now and then.
The judge is all that remains of an entirely separate component of the game called the “contest” that we ditched during early playtests. It’s something we might bring back in the future, but our approach wasn’t working. So we’re simply left with the judge, who replaces a wine order to a certain extent (except he doesn’t pay you for it).
