I'm going to put a rootbeer recipe here and if you follow it exactly I promise you will not think it is thin. I promise. And, don't use any maltodextrine.
- 1 Bottle Rainbow Flavors Rootbeer Extract
- 4 gals of water
- 2 lb Dark Brown Sugar
- 6 Cups White Table Sugar
- 2 Teaspoon Vanilla
Heat 1 gallon of the water and add the sugars. Stir until dissolved. Dump this and everything else into the keg and carbonate.
I can't help you if you're bottling, I don't do that with soda.
