Back then,we used to shop at a grocery store called Meyer Goldburg (yeah! Goldburg!lolz). That was when we noticed Stroh's Bock. It wasn't just coloring,it actually had a smooth darker flavor to it. Even Pizza Hut in our area carried it for years. And since I & my buddies were 18 when it came out (legal age at the time),we ordered a few pitures of it. It was really good. Seems to me it was in a yellowish can as well.
Sure wish they still made that one. Good stuff!
