That sounds fascinating Scary and I would love to know what microorganisms are in there. It just may be a missing bit of a jigsaw. This is not what has become known as EMs because that is a term used by Sustains for their product. Even though it certainly sounds like a different group of effective microorganisms which requires a different growing climate i.e. refrigeration as apposed to a higher temperature.
However there are sites I saw when I first started and information was more freely acceptable, and this would be a sort of starter medium which you would take and put in a wide necked container. Then take it outside put a fine mesh cover over it to keep out litter and unwanted wildlife. Place it in an organically rich area where it can escape disturbance, such as under shrubs or bushes. It can then become infected wioth the wild yeasts and fungi etc which thrive in your local habitat.
After 10 days, bring in and strain. Add 50mls molasses to every litre. Place in a jar and fill to leave only a little airspace. Add an airlock and put it in a warm dark place for 10 to 14 days.
According to the reports you will then have locally grown microorganisms that work and grow in exactly the same way as EMs
I want to try yours though scary and see what it tastes like and what it works with.
Oh my what a trio. Kombucha, EMs and then the scarybrew.
Why sir I could conquer the world
