First of all let me say I really appreciate your help here on the forum! When I started diy I bought flavors of Pink Spot, Mom and Pop. You don't have to add anything but unflavored liquid. I like a lot of the flavors but some are just too sweet. I'm not such a sweet tooth and I was wondering how I could tone down the sweetness of these juices, without cutting down on the taste. I thought of bitter wizzard but that's for tobacco's. I thought of Sour but wouldn't it become sweet and sour that way? Is adding vinegar a good idea? Sorry for all the questions but it would be a waiste to buy something I wouldn't use.
