Q: How long does tempeh culture stay active. The Farm says six months. How much leeway is there? Bulk seems cheaper and more convenient if the culture keep. Would storing itin the freezer, like bread yeast, prolong its life?
A: I’ve stored tempeh spores in the freezer and had fine results a year later. Eventually there’s some loss of vigor. GEM cultures states it this way: “Our laboratory tests show pts (powdered tempeh starter) to remain potent for 6 months or more, after which the incubation time may need to be longer, or more starter may be needed per pound of beans.”

I would like to try making tempeh at home. I live overseas and can have the starter shipped to me as long as it is the dry one you mentioned. Can you reommend where I can buy that type on-line? Also, I was hoping to use my yogurt maker as the incubator. Do you know if that will provide the right temperature for fermentation. Thanks for your advice.
