December 6 is the Feast day of
St. Nicholas, one of several Patron Saints of Brewing. St. Nicholas, Bishop of Myra, was a wealthy and generous man. His generosity towards others led to him being the inspiration for the tradition of Santa Claus and gift giving. It's not entirely clear why Nicholas was chosen as a Patron Saint of brewing. Tradition states that Nicholas was having a beer at an inn where the inn keeper had murdered three boys and packed their bodies in a barrel of brine. Nicholas was offered some salted meat with his beer. Due to a local shortage of food, Nicholas became suspicious, found the bodies, and brought the boys back to life. He died on December 6, 345 A.D. or 352 A.D.
