As yoghurt is probiotic, i.e. contains live cultures, it can be ‘reused’. However, not all yoghurt cultures and yoghurts are equally suitable. Some yoghurts made with ready-made yoghurt remain very runny after just 2 reuses, which indicates that there is only a small proportion of live bacteria. So it always depends on the experiment.
JG ALLE - Do you always have to buy new yoghurt to make more?
