Homemade soda alternative

With our new family diet I am very limited to what treats my family gets. I have had to be very creative with offering treats. I just can not keep even honey around otherwise my kids eat it in anything from herb teas to yogurt. I finally switched to Maple syrup just because they don't think about it to sweeten.

Today I came up with a good reward treat that works for us. Homemade pop. It's simple and unsweetened. Root beer extract and carbonated mineral water. Other extracts can be used like cherry, anise, or vanilla. I prefer essential oils like grapefruit or wild orange. The root beer really offers the flavor without sweeteners.
For those of you that just can't quit pop or want to offer your kids something other than pop or treats this works well for my family.

Now I just need to find a pure organic extract for my family.
