Decarb question

I'm curious. Would heating an alcohol based tincture in a double-boiler to evaporate as a last step accomplish essentially the same thing as decarb? Thereby converting THCa to THC?

Yes and no, mostly no, it will do it a little bit, but the temperature difference between the alcohol solution in a double boiler and just the weed in a oven is big difference. A double boilers max temp limit is about 100c/212f give or take a few depending on atmospheric pressure. A oven set to 232c/450f for about 30 min is twice as much heat. about 52% more. This is the standard temp/time for most decarb tutorials I've read. It would be best if you decarb before hand then diffuse into the alcohol and evaporate out. I like to toss my alcohol extract in sugar then dehydrate at about 130c with the oven door cracked open and the fans on high like as if I was broiling something, OVEN DOOR MUST BE CRACKED OPEN or the vaporized alcohol will flash ignite in the oven and go boom. Stir the mixture every 15 min or so, should take about 1 to 1.5 hrs. The sugar dries and become crystal again. add into teas or bake with it. Can also infuse weed into fats using a crock pot and if temps hit 350ish in the oil then no need to decarb . FYI, use food grade products meant for drinking and eating, no Isopropyl alcohol aka rubbing alcohol. Get everclear or whatever highest proof you can find. Good Luck!

Thanks @mOuse! I make a lot of tincture and typically use Cruxx 190 proof from AB since Everclear is not available in my area in ON. Gosh it's expensive though with the shipping running more than the cost of the product. For these tinctures I decarb of course. My question, poorly explained I'll admit was in relation to sugar leaf tincture made with 152 proof vodka. The material is so small it just dries right up if you try to oven decarb. And it's pretty low potency to start with so I was wondering if a bit of time in the double boiler might help. Thanks so much for the sugar/oven idea. I'll give that a whirl.

I think if you double boiled the tincture at 250 F for 30 mins it would evaporate a heap of that liquid off and you’d be left with FECO but yeah if you did heat it up for that long it would work . Be careful with those alcohol fumes tho they can go up right quick
