According to Benz Beverage Depots’ facebook site, the 2013 Bells Expedition Stout is out and on Eastern Iowa Shelves. At Benz, it is selling at $16.99. I still think you can find the 2012 in select Hy-Vees throughout Eastern Iowa as well. Here’s more about Expedition Stout from Bells website:

The darkest beer we make; this Imperial stout contains double the malt and five times the hops of our Kalamazoo stout and is perfect for cellaring as its complex character will evolve over time. Available October-March.
