Yes, it's real. From Thrillist:
Weekend Bulletin: The Anchorman's favorite booze — and his own brand at that — is coming to market and a liquor store near you. In some of the best news since Ben & Jerry's made primetime and LEGO got that signature coif, Great Odin's Raven, a Scotch (of course), is hitting shelves sometime this December. While exact pricing and availability are still unknown, there has been breaking updates that it is indeed a 40% ABV blend of whiskies from Speyside, Highlands, and Islay, featuring a healthy amount of jazz flute fruit flavor.
