I was really young when I tried this and very intoxicated so I'm not sure if this is any good, but I thought it was unique. Grab a tall glass full of ice then add the Vermouth; root beer is next. Mix it .70/.30 respectively, or whatever you like. I thought at the time it tasted like grape pop, but I don't have the ingredients at this time to try it again. Let me know what you think.
