Non alcoholic wine should not be bad for your liver. It is the (excess) of alcohol that damages the liver. The “normal” human liver can safely process about one “normal” alcoholic drink per hour. Drinking more than that starts to stress the liver.

Most of the drinkers forget about alcohol free wine or when they think about various types of wine they drunk or desire to drink. Non alcoholic wines are great option for pregnant women, designated drivers and for persons on medications due to some heart or some other disease. This type of wine is also good for those people who want to keep the taste of wine in their life without the effects of alcohol.

Not a fundi but this will not seem practical as sugar and yeast are naturally occurring in wine though yeast is added.Non alcoholic wine usually has alcohol extracted by different methods as alcohol is the the result of sugar and yeast combining. Perhaps better to just add alcohol percentage of 11 -15% as per your preference which should be clean without and flavor enhancements.
