Saw this. Interesting with oil.

I would just like to say this thread is wonderful! I've been doing research on tinctures too and I would like to add one thing:

Alcohol tinctures have a longer shelf life and kill mold (for those of you who recycled some infected buds) so keep that in mind if you plan on storing your tincture for a long time.

I am wondering, will heating and/or freezing my ALCOHOL tincture increase potency? I've heard mixed reviews.

I am also wondering if anyone has tried using FRESH trim and FRESH buds for their tincture? This is what I am doing because from what I've read, cannabinoids break down as bud dries, and I want to get every last bit of the plant. Is this counterintuitive/fallacious?

I've also read that grape extract can aid in the extraction process? Any word on this?

*One tip when grinding your bud in a coffee grinder: Grind your fresher/greener trim first (to clean out any spent coffee grounds you may have missed) then grind your highest quality material second. This way you can scrape off the resins left along the side of the coffee grinder, its kinda like finger hash Finish by grinding a bit of fresh or dry stem. All of the remaining resins on the sides will have stuck to the fibrous ground stems, making the cleaning process much more efficient and easy.

Hey guys, i'm a newie here.

thanks for starting this thread, Hobbes, i really want to make tincture 2 weeks out from exams, now :P.
I've got a couple of questions, though.

I plan to do a hot extraction, but i don't have a coffee grinder. what can i use to achieve similar results?
would there be any difference if i used a convection oven? i figured since it's portable i can take it outside (less stink), but the air circulation will throw off my baking time a little bit. plus the fan might just blow all my weed everywhere so i'll have to make a little foil envelope or something to keep it in.
also, about how much rum (volume wise) is in an oz? I'm australian, and maybe it's just an american thing, but our alcohol is sold by the volume.

Cheers
grunt.

Hey guys, sorry for taking so long to get back to the thread.

"I plan to do a hot extraction, but i don't have a coffee grinder. what can i use to achieve similar results?"

A mortar and pestle once the plant material is bone dry. It'll grind into a flour easily. You could use a steel pot or bowl and a wooden dowel rounded on one end.

Another excellent option would be a rolling pin. Probably the simplest, but it won't give you as fine a flour as a M & P. Plant matter must be bone dry.

Convection oven outdoors is great, I often use a hotplate for boiling bud and dregs out doors.

.

"also, about how much rum (volume wise) is in an oz? I'm australian, and maybe it's just an american thing, but our alcohol is sold by the volume"

1 oz alcohol ~28.37 ml

A standard shot of alcohol in Brittan is 25 ml.

Hey True

"I am wondering, will heating and/or freezing my ALCOHOL tincture increase potency? I've heard mixed reviews."

My understanding - once the THC is decarboxalized (by air/water/bake cure) any additional heat will degrade the THC, making the tincture more sedative and fuzzy headed until too much heat destroys all of the THC over time. Freezeing will slow or stop the degradation of THC but will not aid in decarboxylization. The only method of freezing that may help with potency (I haven't read anything on it yet, speculation) is a cold alcohol extraction in the freezer below 0 C.

.

"I am also wondering if anyone has tried using FRESH trim and FRESH buds for their tincture? This is what I am doing because from what I've read, cannabinoids break down as bud dries, and I want to get every last bit of the plant. Is this counterintuitive/fallacious?"

I do, but how I prepare the fresh bud depends on the method that I'm using. If the method has enough heat and time to decarboxalize the THC during the process then I put the fresh bud in as is. If it's a cold or warm method I bake the bud (in a toaster oven, in my grow room, beside my carbon filter) to do a quick cure. The cannaboids must be cured somehow before you ingest.

.

"I've also read that grape extract can aid in the extraction process? Any word on this?"

No, but if the grape extract is acidic it may help dissolve the resin quicker. Thanks, that's some good stuff to think about. I use grape seed oil as a medium, it doesn't dissolve resin any quicker than olive oil. I'll pick up some grape seed extract.

That's a great video, thanks Grinch!

Make a light grape seed oil tincture and cut it with alcohol for quick absorption. Fantastic!!

Hey just wanted to keep this awesome thread going by adding a VERY useful link I've found while reserching.

THC Vaporization points:

(c to f conversion: http://www.wbuf.noaa.gov/tempfc.htm)

Also, I believe that heating pads DO aid in decarb. for the old fashioned method because it has made my tincture much more 'milky' since using it.

For reference, Sunbeam heating pad surface temps:

Thanks to Sweet Baby Ruth & Hobbes for inspiring me to go ahead and try this. Nice info on the grape seed oil, let me know how the seed extract works, if at all.

Does anyone know if its possible to boil everclear @ 225F? Or will it ignite? I know the boiling point of alcohol is 172F...

Maybe a good pressure cooker can contain those gasses and raise the boiling point. Don't know how much though, just that they can cook beans MUCH faster then stove-top.

Make sure you have a good one, don't want the top to blow off and release a huge cloud of alcohol vapor. Test a new pressure cooker on a batch of beans or something first. Definitely do it outside as well, so if it does blow no worries.
