Takes 1.3 cups of mix to make 1qt of rootbeer. Compared to half a cup of Pepsi products. Yet I really enjoy the taste. The. Calculation of the mix is a bit of a pain. The cost is a bit higher than I'd like, but that might just be due to the size of the bottle. Yet if my math is correct. Make approximately 14 qts $0.4 per 1qt soda stream bottle.i miss Barqs, so this is a great alternative.

Fantastic
