interestingly this may have solved a mystery or a myth. rolling rock beer had a 33 on the label that no one seemed to know the meaning of. in slide 52 of chicago there is a huge sign for pabst blue ribbon beer that lists it is blended 33 to 1. wonder if the 33 on RR meant it was also blended 33:1 ( whatever that means)...but it must have been an important selling point at one time...
actually looked it up and found this...
