Another Tincture Thread - Try it, You'll like it

That's correct but you can also throw a second run in there if you want.

 

It rinses the first run and gives you a few more percent of cannabinoids, not as much as the first run but enough to give it a boost.

 

It's in the guide at the front of the thread. Follow the guide. That's what it's for.

Correct.

 

Don't let it go to your head.

 

It's a matter of diminishing returns and isn't really worthwhile to do a third run. If you combine the leftovers with a lot of other leftover batches and really concentrate it then you get something you can use. Take a little of the wet material from the second run after straining and let it dry out then smoke it and see for yourself.

This is probably the last of the test results for heated decarb since it now has been established that the parameters for a successful conversion is the same for newly harvested or aged up to a year at least. Not only does it show a 98.5% conversion rate but it also illustrates how to tell the approximate harvest time of the sample if you have an original, raw, sample.

By looking at the ratio of THCA to THC of each sample, we can see that the older one has considerably more THC than THCA due to the aging process but the point needs to be made here that it still took the same time/temp to get full conversion. That indicates to me that unless the material is so aged that it has less than 1/4 unconverted, it will still need 240/40.

We also see in this fresh material that more of the cannabinoids were retained than the older one. One interesting thing is that the raw sample had undetectable CBG, CBN and CBC but quite a bit of CBDA and the decarbed sample detects some fairly high values of CBG, CBN and CBC but no CBD which indicates that at this temp/time combination the CBDA is going directly to the other cannabinoids. And by conjecture, since it isn't listed, the raw sample had a good count of CBGA which is the building block that determines the ratio of the other cannabinoids other than the THC isomers. The CBGA works in conjunction with enzymes in the plant material to transform it into the other cannabinoids, like RNA, not DNA, in the human body. This is really the first of these dry samples that we've seen that at work but we've had a hint of with the GD samples

So look it over. I think it's enough verification to definitely say 240/40 is the way to go. I may have some two year old Blue Jewel to check again to get a better idea on aging but I suggest the full time/temp up to 2 years of age until I get results that show otherwise. If someone else has some aged material with the known age then this would be a good project if you have access to a lab and some curiosity.

That's my theory at the present time projected from the information we already have. We've seen that it takes that temp/time whether the material was a year old that's already half decarbed or a few weeks old with negligible THC. If it has over 75% conversion due to age then I think you could probably do a lighter decarb for the rest so that you can try to keep more cannabinoids. This is just conjecture at the present time, just some extrapolation since it's so hard to keep enough of something for testing over a matter of years which is the only way to really know, I guess.

 

It seems to me that once it reaches 2 years it's probably at the same decarb level as we have at 225/30. I've used 2 yr old material without decarb a lot and got great results and I probably would do the same today. The fact that you didn't decarb the material after that age doesn't matter with the topicals. Those cookies of mine at the time, using 225/30, probably had a lower conversion rate than your non-decarbed freezer stored older stuff. And you probably got more of the other cannabinoids since you didn't heat it.


There's a lot of factors at play and as we've seen, there may be reasons to not fully decarb so in a way it's going to wind up as personal preference instead.

 

I'm excited, too, especially if that Everclear is 190 proof. 8 bottles should last a couple of days. That new thermometer should help. Let us know how it turned out.
