Most have an alcohol content of about 0.5%…its a fermented product, so not possible to make it completely alcohol-free. Most carry a mention on the label, but its not enough to be a huge risk…less than eating a main dish cooked with wine. Ymmv.
There are a few that carry a 21 and up label…I haven’t tried them.
I would highly doubt that you’d find a brewery that makes it…the fermentation and the SCOBY are very different than the brewing process for beer.
