Cultures for Health Natto Starter Spores | Traditional Soybean Japanese Food | Great Source of Protein, Vitamin K, Probiotics for Digestive Health | Gluten Free Vegan Plant Based Meat Alternative

Clear directions and worked great to make natto.

Never had a failure on the use of these for making Natto. Arrived and was in good complete order.

I tried two times. I had sterile equipment. Filtered water, no chlorine. Properly hydrated and cooked beans. Temperature regulated environment, not less than 100 F no more than 110 F. Proper aeration. On the first batch I was seeing no fermentation and the beans were acquiring a bitter taste. I added an extra packet to that batch. Still nothing. Second batch, smaller, was even more careful. Between 105 F and 110 F. Neither developed natto's signature taste, aroma, or slimy, stringiness. This product is bogus. Don't waste your money. I'm going to try a natto bean powder which users have said is still active and can make natto (available here on Amazon) and frozen natto from a local Asian food mart. Very disappointed.

What can I say? If you want to make tasty Natto, these are the spores for you! I've used the Nattomoto spores in the past, and had several failed starts. Once I found Cultures for Health, I have had multiple successful natto batches with no failed starts. I use the smaller sized soybeans , and the taste, texture, and stringiness of my Natto has been excellent with this starter.

This is a great product that I’ve used consistently over the last few weeks. It makes beautiful and tasty natto. This last package had one of the spore packages open on the bottom so when I shook the package to get the spores away from the top it dusted my kitchen floor. The other 3 packages are fine. Maybe there is a way to do a check before mailing? This is a very good product and I will continue using it.
