I've seen older vintages around (not sure if that's a new drop) but nothing from this year. Haven't bought DSDB in a while but I'm interested this year.
If I remember correctly, they are going to put it in cans this year. That is a game changer for me, because it's getting tough to drink a 750 by myself.
It's coming. I had it on tap at The Whistlepunk, in Stone Lake, over the weekend. They had a Bent Paddle rep there, with 4 of their beers on tap. Doubleshot Double Black was delicious.
