What are peoples thoughts on shelf life of E85? Meaning how long before it's bad(in tank or out), or not something to worry about? Believe it absorbs water correct?

My gut says the stuff in the dsm is junk, but curious what others have read, or had experience with.

FYI, I just realized I didn't drive the dsm last summer.. which means it's been sitting since Nov 2010 with the same E85. Basically last April I started the car up for the season and went down the block, car ran like shit, I parked it, and never got back to it(a that point, the fuel would have been 5 months old). Wondering if its likely the fuel? Being lazy because I think it's almost a full tank of bad E85 I'd have to drain if so.
