Seems more a case of dutch/english spelling mixup of the word 'saint' (sint=saint). The Sint Sixtus abbey is located in the town of Westvleteren. There are a few 'Westvleteren' beers, the most famous is the Westvleteren 12 Belgian quadruple. It's brewed by monks who only want to cover the expenses of their abbey, so supply is limited. You can try to reserve a spot in the queue (by phone) to come to the abbey to get a case. Some specialty stores carry it but with a heavy markup (>10 euro's per bottle). I'd recommend trying it for the rich flavour, but there are comparable beers for half of the price ;)
