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

That's called a natural decarb and it takes 4 months if using fairly freshly dried material or 3 months if using material that has a large amount of THC already converted due to age/condition, like cartel stuff. I prefer the natural decarb because you lose no terpenes, esters, flavonoids or any other beneficial compound due to heat. Your reduction is done naturally. I swear by it but you've got to have some regular GD on hand to get you by during that 3-4 months.

You make it the same way but without the heated decarb. Over the course of the four months it will usually turn gold, too, if it wasn't before. It can be used after 3 months and have it be as good as a 225°F/30 minute heated decarb but 4 months gives you a really nice profile. Here's my study results on that using freshly dried material. I have a couple of others, too. Another Tincture Thread - Try it, Youll like it

You can also decarb your oils after infusing but that uses heat although the oil preserves the compounds better than the direct heat of an oven decarb of the material.

 

Yes, Stiggy, I would recommend our normal "freeze and squeeze" extraction just to get it out of the way. You don't extract more cannabinoids by letting the material sit in the alcohol for a few months, just chlorophyll. If you strain it first then you don't have all that stuff if you lose it for 2 years.

My thanks go out to OldRose for being willing to help with our CBD project and she has produced profound results right off the bat. These results are from her lab and include the raw flower, 2 decarb temperatures, raw tincture and a lightly decarbed tincture. The large image is the comparison provided by the lab with some highlighting and the addition of the percentage tables added by me. The thumbnails below it are the individual results.

The 175°F temperature range was a result, I think, of a misunderstanding. When the lab tech was asked about the decarb temperature for CBDA to CBD, the result was 176°. I'm fairly certain that should have been Celsius instead of Fahrenheit because that's what all the lab techs I've ever spoken with have used. If that is the case here then that is 348°F. As you can see by the results, 175°F didn't faze it.

Oh, man, but the other two flower samples have nailed it, to my mild surprise, and also to my greater surprise, we have a strain with CBDV. I have never seen it on any of my tests and probably is detected due to the higher CBD isomer profile but my AC/DC and fake Harlequin didn't display any. CBDV is very, very effective for epilepsy and spasms. This needs to be followed up to see how prevalent it is and whether being a Sativa or Indica plays a part. That's exciting to me.

The biggest surprise is found in the reversal of the CBDA and CBD values between the raw flower and the 240/40 oven decarb. The comparison chart uses mg/g and that's why I included the percentages below it for those two since % is what most folks find easier to work with.

The thing we're looking for here is conversion and stability of the CBD isomers. In all of my previous tests I haven't seen much indication that CBDA converted to CBD as much as it did to the other cannabinioids like CBG, CBD, CBN, CBC with little change to CBD from whatever was initially there. One of the things I've been most curious about has been about learning how to get a good CBD decarb without destroying all the other compounds, or most.

The raw flower had a value of 13.9% (139mg/g) for the CBDA and 0.6% for CBD (5.9mg/g). In the CBDA/CBD project my lab ran it indicated throughout the range of times and temperatures that there was little to no conversion so I was pleasantly surprised to see that the values had basically been reversed in the 240°F/40 minute decarb. The CBDA was only 0.7% (6.5mg/g) but the CBD had increased to 13% (129mg/g) and there was no CBN detected at all nor was there any appreciable increase or decrease in any of the other cannbinoids. It should be pointed out that all of the THCA converted to THC, all 6mg of it.

That was a very important discovery because it shows that CBD can be converted from CBDA without losing your other compounds. We need some further independent results to be able to definitively say that this is absolutely true but it does look very promising.

We will follow the progression of the Ringo's Gift raw tincture to see how it cures in comparison to my AC/DC over the next few months. The 175° tincture didn't have much difference and I suggest that it be added to the raw tincture since those values are so close anyway.

There is one feature of these lab results that I really liked until I took a little closer look but it's still interesting. In the individual results the lab included fields for trichome density and maturity. Using a percentage basis they listed the amount of amber, opaque, clear and translucent trichomes there were in the sample. I don't see much difference in the last 2 but what do I know? So, I thought this was a cool feature until I added up the percentages of each of the categories and found that it adds up to 200%. I guess we'll just have to take that one with a grain of salt.

We'll have more on this as we go along. I'm sure I'm forgetting something here but there's nothing new about that.

Oh, not only was I taking 100mg of prednesone daily but also huge doses of immunosuppressants and intense antibiotics and narcotics all at once and the prenesone was the mildest of the stew. I had some nightmares that still give me the chills. Unfortunately, asthma is one of those things where long term use of the stuff can make a difference between life and death. It has some serious side effects that I am now experiencing and makes quality of life quite challenging, though.

Cannabis edibles and tinctures helps considerably and can even help with asthma so that you won't need as much of that pharmaceutical stuff.

 

As of now the trend is 240°F/40 minutes for the conversion of CBDA into CBD but don't take it to the bank yet. We have yet to see if that's really the case. The tests I've done with high-THC stains using the same time and temp hasn't really shown that but it has a lot less total CBD/CBDA in the mix so it may not manifest at those times.

I'll take in the 1 month sample of the AC/DC natural GD next week and we'll see just how that goes.

 

It will become a Gold Dragon by the time that 4 months is over so that shouldn't matter.

 

Boy Howdy! Terpenes are all the rage. These flavors used in the distillates are comprised of terpenes, Live Resin is all about the terpenes. One of dispensaries that I frequent now offers to customize your terpene profile for the oil cartridges they sell.

The science is passing us old farts by faster than we can keep up with but so far I think that we've done a pretty good job here. Just think how I must feel about the highlighted area. I started out here being mocked and ridiculed and now I see all the things we've been doing every time I turn around as if it had been SOP all this time. I'm sure it's just coincidence.
