I will say this, I do yogurt home for a long time, they are very helpful for the stomach, in case of problems with Candida, as well as to enhance immunity. I use yogurt Vitek owners manual, I tried many starters, some better, some worse. This starter is not bad, but if I lived in Russia, I'd better buy something there, because the choice of a lot more than on this site. For my taste turns sour yogurt, especially when it ferments again, but in principle this acidity typical for yogurt with probiotic cultures (by the way it is these yogurts perezakvashivat better not at all). Price is good for 6 bags, so I think that I will take more if you do not wait parcels with Russia.
