Kombucha alcohol content

[Boochdaddy]

Hello. I am a kombucha home brewer who’s in the process of going commercial. I had some kombucha I brewed tested for alcohol content and it was over the 0.5% level. I am trying to get the alcohol level below 0.5% by reducing the amount of sugar in my first brew, lower the temperature of F1, and avoiding sugary additions in F2. I am hopeful that this will help and result in good results. Does anyone have similar experiences and advice to offer?
Thanks !
