I came to this site looking for more information on PS128 probiotics.
In particular, I found the posts by WinnieThePoo a great help.
I am learning to produce PS128 Yogurt, notwithstanding the obstacles put in my way by the popular electrical yogurt maker featured in posts having a problem with temperature control.
My first batch failed as the unit heated 10C above the temperature displayed . I managed a second batch by compensating for this, but am tempted to get an old fashioned stainless steel flask type.
