Hello all, I have a question that I feel can only be answered by an expert, not by random internet searches or by personal experiences. There may not be an answer but, if there is it will come out of a lab or some other lengthy trial. I aim to tincture some reishi mushrooms that have grown under my care and my question is about the proof or percentage of alcohol used. What is the ideal alcohol content for a reishi tincture? Some say to much will damage the compounds, others say to little is ineffective or insufficient as a preservative. Also, for double extraction, do I tincture first and decoct later, does it matter the end result proof or only the proof during extraction? Can I make a decoction first and add that water to create the perfect proof and finish with tinture? I'm really excited about my new mushroom hobby but, as a realist I would like to challenge everyone out there, mushrooms will not be able to save the world, much less me, with out a free flow of accurate information that the worker bees can use to proliferate this technology. Thanks in advance for any accurate, expert feedback on this matter, and thanks to anyone who has taken the time to study these matters and who still has time to play around on the Internet.
