I used it on my first batch of SP. I later learned that the Italian juice is not buffered for PH so my SP was EXTREMELY acidic. Unfortunately, I also back sweetened with pomegranate/cranberry concentrate and that added more acidity. It was undrinkable by itself because it would almost eat the enamel off your teeth. Made a good sangria though. So, bottom line, if you use the Italian juice, be ready to check PH and make adjustments.
