LAB collection: barley, Oat?

I would have to say yes being that LAB lives on everything and everywhere and that the starch collection will still attract the LAB from the air and that by propagating in the milk u should still get a LAB only full spectrum solution afterwards One of the ideas behind KNF is that u use what is natural to u theres not many very specific things that r done only X way i think many things r more bullet points that u wanna hit like in LAB its attract with a simple starch propagate in any animal milk i dont feel the source of starch  or milk really matters as much as the method to achieve the end results Same as would be in the next step of LAB to preserve it well how much sugar u add is irrelevant because its the super saturation point u r trying to achieve and the amount of sugar u will use to get there is undetermined what matters there is u use brown sugar to lock up all the water to place the LAB in hibernation for storage Things to think of is what may work it Korea may not work in Arizona but the method still does its how to adapt to your Naturel environment and make it work for u

I have never tried with oats but I am sure it’ll work, especially since rolled oats have so much starch dust, similar to white rice. brown rice doesn’t have nearly enough starch to wash off, and barley is probably similar. But enough theorizing. Let me tell you what I HAVE seen work (besides white rice.) Cassava starch wash, cooked taro, potatoes, and perhaps most surprising of all, mushed up white bread and flour tortillas too. Hey, its got starch, and that is the most important thing next to using real milk.  Let us know how it turns out with the barley and oats!
