Tried this last night and quite enjoyed it. They've raised the ABV of normal Hersbrucker to 6.4% and dropped back on the bittering hops. It's still very hoppy -- much more so than a German oktoberfestbier -- but it's rather better balanced than normal Hersbrucker, IMO.
Oh, and Oliver said that he wants to set up free tutored tasting sessions every week in Porterhouse Central. If any of the commercial breweries want to take a slot get in touch with them.
