78 is a little bit more of a nod to a classic English pub beer. But yeah, so many of the available packaged stouts are laden with lactose, chocolate, coffee and other adjuncts.
A straight Oatmeal Stout or Porter is tough to find these days in the stores. There are still breweries making them but most package stores don't carry them or they are only available on premise at the breweries.
It might be time to bring back the beer thread...
