@jz i know that there are soybeans grown ecologically here in germany which you can buy, eg. https://www.rapunzel.de/soja-bohnen-aus-deutschland-bayern.html
i don't know if it works with other legumes
@jz kein problem :) diese kleinen reformhausläden haben manchmal echt ganz gute sachen, lohnt sich da ab uns zu mal hinzugehn :)
wo kriegst du denn die bakterien zum natto animpfen her?
@bonifartius hehe i know, i often go there... but was surprised to NOT find the soy beans there... will look further, thanks!
For the starter i am still in my preliminary phase of research... found this https://www.nattostarter.com/makenatto.php in the EU. If you have any other source i am interested!
@jz thanks! will look at their stuff :)
@bonifartius genial! danke!!
