Last I checked it wasnt at their brewery anymore for growler fills and that has also been the only way you could get keane.
Yeah I had it twice on tap 3 separate kegs this year but not at the source. The 1st keg didn't get me to get a growler but the 2nd keg (had yesterday) would. I dont know what's going on with green flash as it sounds like they are having some big problems with their and alpine brands. I've been told their original owner still brews this one and the keg I had yesterday would make me believe that. Looks like unless someone has growlers stocked up you'll have to wait at least 6 months. For me at least it's the best beer they have when its on and a memory of how great that brewery was.
