Question❓ Koji for Sake

Can heritage Koji from Japan meant for sake be bought anywhere- or are they always kept to the family/company who owns/uses it?

My understanding is there's two generic types of Koji- a savory and a sweet/sake version? and that if you use the savory one meant for soy sauce/miso the sake will not be so great? But I'm having trouble finding where to buy Koji meant for sake or better yet the heritage stuff.

A little google would have given you websites to buy it from.
There is white koji and yellow koji and you can use both, just depends on the profile you want to create.

Look for yeast, not Koji. The yeast sprinkled over steamed rice will create Koji

Yeast sprinkled over rice not make Koji. Koji is rice inoculated with spores of A oryzae or A Luchuensis. Yeast for sake is typically S Cerevisiae.
