The pre-mixed kombucha dry tea I bought was super sour, like an arnild palmer. It hit like lemonade on the first tingly fizzy sip. My wife was sensitive to smell so I stopped brewing. I haven't found any kombucha that had that degree of lemonade and icea tea going. I decant into growlers so I actually get a pretty violent pop, even after refrigeration. What I don't understand is why all kombucha is refrigerated, I only drank mine cold because it is smoother that way, but straight off the 78° bucket was fine too!
