Brewery of Westvleteren, inside the Trappist Abbey of St. Sixtus, where the best beer in the world, the Westvleteren 12 (judged by RateBeer.com), is brewed.
The monks don't make this pilgrimage easy. To get the beer, you have to call up weeks in advance, reserving your small quantity, and giving your license plate number so they'll know you're the one who called. Then, when you get there, the silent monks hand the beer out through a slot in the door.
Gesloten. Ferme. Closed.
