Then you should love Rolling Rock beer. Brewed in Latrobe, Pa. since 1939 and at one time were one of the largest breweries in the Country. Well known for their small "green" pony bottles. I called on the breweries at one time in my career path and one of the issues with beer was light which would deteriorate the flavor quicker thus many bottles used were brown to limit light infiltration. Of course marketing often played a bigger factor along the way and along came Miller with their clear glass bottle. After a couple beers who cares?
