I need help. I have some black tea flavoring from TPA. I mixed it at 5% flavor 15% sweetener and 80% 50/50 base blend. And it is not good. Am I supposed to dilute the flavoring be for I mix it? If so at what %. Am I useing to much flavor. If so what is a good % to start at. Please help I love southern sweet tea but this is not it! Thanks Matt
