Tempeh Starter Culture


Tempeh is a plant-based probiotic protein, traditionally made from soy. It is similar to tofu, but many people prefer tempeh due to its probiotics and higher content of protein, fiber and vitamins.

It is a great meat alternative and can be sliced, marinated, or seasoned as desired.

With our heirloom starter culture, you can make an endless supply of rich, nutty tempeh in the traditional Indonesian way!

Easy and straightforward

I found the tempeh incredibly easy to make! My house is cold, so I used an oven with the door left ajar and containers of hot water to get the temperature right. It got cold overnight, but my tempeh had enough of a head start that once I got it warmed up again in the AM, it got right back on track and was white and fuzzy in no time! I think I might have even messed up - I put the inoculated beans in a plastic container, about 1-1.5 inches deep, with no holes on the bottom and a cloth to cover it on the top. I had no issues with the beans going bad. So excited and looking forward to making my next batch!

Delicious tempeh

Although it’s a bit tedious to prepare soybeans for the fermentation process, the resulting tempeh is SO much better than any I’ve ever bought. Really worth my time!

Starter Culture easy to use

I have a book on making tempeh, but the instructions were fairly close. I thought I killed the culture after about 16 hours or so of incubation in the oven with the light on… I checked the temp, and it was up to 111 degrees. I removed it from the oven, and left it on the table top to wait and see. After another 12 hours, I started seeing white mycelium growth on one of the two bags of beans. By the next morning it was getting nicely covered (the other one, not… now I was sure I killed that one). Long story short, both bags covered and filled in nicely with mycelium. I had to try some right away, so marinated it with some homemade shoyu koi, and then pan fried it. DELICIOUS!! Best tempeh ever! Just bought my second batch.

Tempeh Starter

This was fabulous. I made tempeh for the first time, and as most newbies/first timers I was nervous. This starter made the best tempeh I have ever had. I would recommend to one and all.
