Greetings, I have been working on a decarb/tincture process using grain alcohol and after about a dozen attempts have gotten the strongest product possible. I am now wanting to make a very large batch of this stuff for my own personal use but wanted to find out what the shelf life of thc is in a grain alcohol tincture? Are there any studies on this? Or does anyone have first hand experience with years-long shelf life of thc in a tincture (non-glycerine) like this? I tried the search function but couldn't find anything pertaining to shelf life of everclear based tinctures. Thank you in advance to anyone who can provide insight.
