Want the Alani Witch's Brew without the caffeine!? ME TOO!! What you'll need to make the Alani Witch's Brew DUPE!-Can/12oz of Club soda (I like to use lime club soda but a flavorless one works as well) -Caramel sauce or syrup -Green apple flavoring -Citric Acid (if you'd like it a little more tangy, but you don't HAVE to use it!)
