Hello! I've made my very first batch of L Reuteri and it was a very good result. there was some separation, but very little. And the taste was fantastic! I'm looking forward to seeing how my subsequent batches turn out, although I'm rather confident they will be fine as the process of making the yoghurt is so easy with the Reuter-i Pro yoghurt maker. Just make sure the unit and the container are VERY clean, add the ingredients, and with the simple push of a button, you're on the way to making your own nourishing and tasty yoghurt.
