Go better, get a sarsaparilla. Many different root sodas to try, go to the nearest novelty soda shop or check online for small brand, real ingredient, glass bottle, root-based soda.
Edit: I don't know the availability of this stuff outside of the us, but it won't be hard to find in your closest large city worst case scenario. Ace hardware even has a small selection of "real" soda at checkout.
Personally I’m a Vernors ginger ale guy though (and makes a good float with homemade vanilla icecream too). A&W or one of the smaller batch places for root beer.
I tried sarsparilla and it felt like the root beer equivalent of going from Coke to glass bottle Mexican Coke. It just tasted a little bit richer/better to me. But I also like an occasional Virgil's root beer, which is kind of its own thing.
When I take sobriety months, I collect root beers and try to find the best.
Dad's came outta nowhere. Easy 2nd place for me. Had never heard of it. Incredible root beer. I was expecting something meh, idk why. I was pleasantly surprised.
barqs is peak big brand in a can. When its an option I'll always go for whatever glass bottle root of unknown brand is in the fancy drink shelf though.
