I just added seltzer to my home bar taps and would like to use it with syrups(hand pump style) to make soda. Ive found a few sources of gallon bottles and bag in box syrups but all of them are made with high fructose corn syrup. I then remembered my local brew store sells those 2oz bottles of soda extract, but they are intended to carb via yeast in bottle. So now what im wondering is if anyone has tried using these as flavoring in homemade simple syrup and then using that as the sweetened soda syrup to make soda from seltzer?
