homemade fermented soy sauce safe raw?

Question

I am fermenting homemade soy sauce for the first time, and followed this generic recipe (that has no pictures).

Technically I made tamari, because i did not to put wheat / gluten into the mix (just soy bean, water and salt)

I am about 3 weeks into the 'in salt water' fermentation part, and am wondering 3 things:

1. is it safe to eat raw?
2. is the soy sauce supposed to turn black, or is brown normal?
3. subjectively, is it done?

below is how it looks now.

Here is how 'moldy' the wet soy beans were before i started drying them. Only one piece had a big visible piece of mold but i did leave it out for a week.

and this is 'how brown' the dry soybeans were before putting them into the salt water

it has smelled pretty bad the whole time, but now its not smelling so bad, it feels like it smells better, or i am just getting used to the smell.

thanks

Answer 1

Pretty much all the commercial soy sauces, after fermenting is done, press the mash, and the final step is to pasteurize the sauce. This not only kills mold and bacteria, it also alters the flavor in a favorable way, as well.

For both safety and for a better homemade product, I'd recommend heating it, though I don't know enough to say it's dangerous when "raw", specifically.
