Kefir drink in Poland [79]
bogutynmlyn.pl/go/_info/?id=2987 live kefir cultures in sachets enough for 20 litre of kefir
I have done my own yoghurt which is simple - self made stuff is also tastes much better than the ready-made stuff from shop - all it takes is to buy natural yoghurt once - you need to boil milk let it cool down a bit and then add natural youghurt (half of the cup per litre of milk) and keep the mixture in a warm place (like on the radiator in your home in winter)
if that fails ask around about 'ziarna kefiru' which is the same as kefir grains (use iwona.com to hear how 'ziarna kefiru' is pronounced)
