Kvass can be as low as 0.5% alcohol by weight, but traditional methods put it around 1%. The widely sold kvass in Soviet Union was 1% ABV. I don't drink at all, so I'm pretty sensitive to the effects of alcohol. I can't detect them at all after drinking kvass. I could feel them after drinking a home-made and even some store-bought kombucha. > There's speculation that letting kids drink the stuff has been a contributor to heavy alcoholism in the former soviet union I doubt it. Other countries also have a tradition of fermented drinks, often based on milk, that are just as alcoholic.
