If you don't have access to kif, then a quick wash of chopped, decarbed bud in a small amount of Everclear (just enough alcohol to cover the bud) yields a potent tincture without any boiling or reducing.
I find that decarbing at 300 degrees F for four minutes is effective. Preheat the oven to 300, then turn it off before inserting the weed/kif.
You're talking about using the cold extraction method...There are a few problems with this method, mostly that it takes 4-8 weeks to extract all the thc, which I don't have. I'm not interested in quick and easy method of extracting a partial amount of the bud's thc, and having alcohol soaked weed to deal with. I'm also under the impression that using the hot extraction method is more efficient.
...I am adding water to the alcohol/cannabis mixture for the sole purpose of removing as much unwanted flavors as possible, because I do not want to affect the flavor of my beer. You can most certainly make a potent tincture without doing this, it would be Green Dragon, and even with the cold method it will taste like shit.
I don't have kief or hash, and frankly I wouldn't waste it on a tincture if I did...
You have a very good point regarding loss of resin during the brewing process. It would be unwise to add THC to beer during the fermentation process, as a high percentage of the THC would be lost to yeast cake
. I therefore intend to add the tincture during bottling. It did occur to me that some of the resin may stick to the bottles themselves, but I think it should be minimal. I may be wrong on that final note however, this is an experiment.
FYI: this shit is fucking potent...I don't have an eyedropper so I can't be sure of how many ml I consumed, but I took what I'd estimate to be 2-4 drops and I was FUCKED!
The tincture I made still has a cannabis flavor to it, although it is MUCH milder than Green Dragon. When I added it to a beer, the flavor was detectable, but just barely...it did not have a significant impact on the flavor of the beer. I think that the next time I do this, I will do a two or three rinses with sterile water to further refine my tincture.
