I don't use alcohol myself due to my health issues. I have not received my machine yet so I'm not sure about the instructions. I'm leaning towards not using water when making a tincture as I am reading elsewhere that water would just dilute it and make it weaker. The heat would not get high enough to remove enough of the water and if you got it high enough to evaporate your going to lose potency in the evaporation. Kind of makes sense but I'm new to cooking with cannabis. Anyway, I will keep posting with updates when I do finally get it. I'll give an initial review, try a decent dose when its finished, then let it age for a few weeks. I understand from what I have been reading that even when using the heat method to make it faster, letting it sit and "cure" will result in a better product. I have no idea on how true that is but I hope to find out, hopefully it works out positively. As for a recipe, it's pretty simple material, glycerin (if that's what your using), lecithin (optional but I will be using it). For alcohol tinctures replace glycerin with something like grain alcohol. It's the amount of material which seems to be up to the individual as for potency, but finding a solid starting point seems hard unless your using hash. Then it's very easy to determine dosage size, and potency of each dose. But using trim or bud it's a little harder to say because some material will be more heavily frosted, some material more oily, larger heads, smaller heads, that all has to make some kind of difference in transfer of cannabinoids to whatever your working with, be it alcohol or glycerin. At least I think. lol All theory to me right now. But I will get it all figured out. If a run with a good amount of very frosty trim doesn't do it for potency, the next step is using kief. That way I can guarantee what will be in there. Then it's up to my body and how it's breaking everything down and absorbing it. I think I might try to make a single 1 oz vial with bho as well and see how that goes. But that will not be in the machine of course, as that is way too small of an amount.
