Westy 12 - Arguably my favorite beer, wish it was more available
Rogue Old Crustacean - Great Barleywine, maybe my favorite.
Dogfish Head World Wide Stout - Did not like this at first, then I realized it's because I didn't follow the instructions and drank it cold. I know much better now.
Victory Old Horizontal - Between this and OC for my favorite Barley Wine
Troegs Troegenator - Mmmm doublebocks
Dogfish Burton Baton - OMG how I love this beer
Founders KBS - Even better than the original Breakfast Stout
Ramstein Winter Wheat Eisbock - Not nationwide at all but an awesome offering from an NJ brewery.
Troegs Mad Elf - It's not christmas time in NJ without Mad Elf
Gulden Draak - First favorite Belgian
Three Philosophers - Great Quad
Old Rasputin - Not a big stout guy as you may have guessed by bock, Belgian, and IIPA dominated list so far, but this one is great.
Brooklyn Black Chocolate Stout - Whoops another stout. Love Russian Imperial stouts.
Oscar Blues Ten Fidy
Carton Decoy - Very wintery and warm.
Founders Backwoods Bastard - Best Scotch Ale
Allagash Four - Swear that's it. That's my last suggestion.
