The question of the influence of kefir on blood-alcohol-level has been asked in a legal proceeding. The questioned recipe consisted of 21 water, 6 soup-spoons of kefir granules (about 120 g), 150 g sugar, 2 figs and one lemon. The consumption took place after two days of fermentation. Experimentally we found, that one liter of this kefir product may contain up to 38 g/l ethanol after 7 to 10 days. On the second day we measured up to 16 g/l ethanol. Our results may be import for expert appraisements concerning unability of driving
