This is listed as a 21°P and 7.5% ABV.
Converting from Plato to SG this is 1.087. Finishing at 7.5% would make the final gravity 1.031. This seems really high. Maybe its the formulas used that are messed up or the stats for the beer are wrong.
Shoot Shaun an email and let him know. I'm sure he will clarify it for you, he is very helpful!!
In case anyone was wondering, I emailed him and he replied, "Yes. On purpose. Crazy right?"
That beer has a very thick and creamy mouthfeel - I'm sure if you degassed a sample it would be around 1.031.
He has a knack for chewy non-farmhouse beers, Edward finishes around 1.015 for a pale ale.
