It works in a different way. Creates an anoxic environment that favors the metabolic process to made the tannins insoluble. Really the same thing as the alcohol in a sealed chamber trick. I have yet to have any personal to try it on, but from my reading, if you can hold the temp at somewhere between 105 and 140, it will done in hours instead of days.
@tonyOmahaz5 these methods have been shown to work on a number of the hybrids. No one’s gotten it working on American persimmons yet, but I haven’t been super impressed with most of the attempts I’ve seen documented. I suspect it’s just a matter of adjusting the time and temp variables.
