my Gf has that kefir in her fridge..in fact that pic looks just like her bottom fridge door shelf...gonna try some next time I'm out there..figures too as she is from Armenia(near the caucasus mtns.)...was just plain scared of it when I saw it..on another note,does anyone have any experience with yogurt makers? and is it possible and plausible to perhaps add a protein mix(e.g. whey) to the yogurt?
