Made recipe as written, and doubled the root beer concentrate, and did turn these into rootbeer floats. Have to be honest, here in town we have a 24 hour drive-in that makes their own root beer, and these had a better flavor. Do have the leftover ingredients, plan on making the root beer too. Made for I Recommend.
This is very good! I followed 2Bleu's suggestion and double the root beer concentrate, but left everything else the same. The seltzer water seemed to loose its carbonation once I added the sugar/water mixture, maybe I should have let it cool some first...This would be good root beer for floats; since there is not a lot if carbonation it won't be so foamy. Made for PRMR.
Great stuff! Root beer is so good but it seems often overlooked around the Coke and Pepsi. I love that you can control the amount of sugar. I made 2 servings and doubled the amount of root beer concentrate. Next time I will reduce the sugar just a tad. Root beer float next on the menu! Thanks for sharing a great homemade, old time favorite.
