Thanks for the followup. Yes, grains will definitely start fermenting once they get wet. The native yeast on the grain is what starts up the ferment. When the ole-timers would make wine they would do what they'd call a "natural ferment" which essentially was leaving the top open and picking up whatever yeast happen to drift by to start up their ferments. The ACV component introduces the bacteria (acetobacter sp.) that converts the alcohol produced during fermentation to vinegar. I like the "scale" you guys utilize. Seems to cut WAY down on the hustle and shuffle that seems to be such a big part of the discussions in this thread.. . . . We didn't even start it w/ acv, didn't know about it, we just started w/ water and grains . . . .
