This appears to be their Fall/Winter offering. I am drinking the offering that must be from this last fall. Still not old enough, in my opinion, to have lost most of it's aroma.
I can see possibly some Vienna in there, but fail to recognize any Crystal in this beer. I am not equating SRM to malt flavor, just to me, it appears to be a very non-complex beer and the SRM for that big a beer appears to be indicative of it not having many other grains in the grist besides a 2-row (american, MO or pilsner) base. A quick calc in Beersmith with 14lbs pilsner at 80%eff and 77% attn comes with numbers that will be close to the Wallop in terms of ABV. This puts SRM at 4.9-5, which is close to my perception.
Maybe it sat around at beer store and got cooled and warmed and skunked a liitle, who knows. Send me a known fresh one from PA and I will reiterate
