The quickest and easiest way to make homemade root beer is to start with Zatarain’s Root Beer Concentrate and mix it with seltzer water or any club soda. Now just find a nice porch swing, sit back and relax – this is living.
Bring water to boil in medium saucepan. Add sugar; stir until dissolved. Add Root Beer Concentrate; stir until well mixed
Refrigerate until ready to serve. Slowly pour seltzer into root beer mixture until well blended. Serve immediately
