Dr. Pepper is my go-to, to be honest. I'm surprised that it isn't very popular at all outside of my state.
There also used to be a brand called Old Tyme that was like that. I miss it.Gimme a strong ginger beer. Not sweet or fruity. I like the kind that takes the back of your throat off, it burns so good.
Stewarts made one like that, a long time ago. Never found anything close to it again.
