What’s going wrong?
I’ve been fermenting L reuteri successfully for 6 months with an unspecified strain from swanson, I decided to try out biogaia gastrus since there is a lot of scientific research behind it and dr davis recommends it (I am aware it’s terrible). First time using biogaia (5 tabs as starter) the lid slightly popped itself off during fermentation (probably from gas) and smelt like cheese so I just guessed contamination. The pictures attached are my second attempt after cleaning more thoroughly and sterilising also using 10 tabs instead but this time was the same but worse and it was flowing over the top and out the sides.
Obviously it gets contaminated after the lid pops off but the real problem is the gas inside gets produced to much and I’m not sure what to change. I do 36hrs and 37 degrees (I live in australia) and I heat the milk to 84 degrees beforehand. It leads me to believe I’m not handling the inulin properly like that needs to be sterilised too but I don’t know how. Would I mix it with the heated milk before I let it cool back down to 37 degrees?
Then again I never had this problem with the other strain and this method. Also australia doesn’t have half & half :(
Farmhouse gold full cream milk is fine though.
Any suggestions? I am going to either try mixing the inulin in with the heated milk before mixing or try fermenting at 36 degrees.
Thanks guys.
