New to the forums, a glass blower buddy of mine told me I should look here for an answer to my question.
I am reworking my gummy recipe, anyone have an idea of what is the best flower to ethanol ratio to get it as strong as possible? Not that it matters, but I am using 195 proof organic cane ethanol from Extractohol. Normally I just wash my RSO off with ethanol while the pressure cooker is still warm (ran at 170-200) but I mix strains in my RSO and am trying to do strain specific extractions for a few prototype batches of gummies.
I’ll take a tek, basic numbers, whatever you got!
and then the whole “strong as possible part”
if thats really all you are after, why not reduce your solvent after the fact? you could extract with 100 gallons for all anyone cares, as long as you reduce your solvent (you should be anyway for formulation) youll have the same amount of thc in the end. “strength” doesnt apply to your amount of solvent (again unless you arent removing it all) it relates to your input crude material FOR extraction, not the solvent being used. (assuming complete extraction ofc)
I am low on ethanol, It looks like I have about 800ml left over from my last gallon. All the herb I’m using is tested. Gotta make a test batch of gummies.
So the 1gal etoh to 1lb ganja ratio is the minimum ratio I should use for this extraction?
edit: and I can just make my ethanol stronger and stronger and stronger by extracting plant material? At what point is the alcohol saturated? Bout to finish some watering and then I will do an in depth search.
So wait with that logic, my tek of washing buds with a hydrocarbon run that’s been ethanol washed (pre winterized) then could actually produce a stronger concentrate? The times I’ve done this tek, it has always been higher in terps than just regular ethanol-winterized hydrocarbon extracts and just regular bucket tek. So… Maybe this confirms a bit of a heightening.
Stronger tincture does not = stronger concentrate once the solvent is removed…
Just more concentrate.
At least to a first approximation. There is certainly some wiggle room around relative solubilities of target vs non-target that might get you a slightly more potent (or less potent) concentrate when pushing the solvent closer to its carrying capacity.
To a point. if you don’t have a centrifuge to remove the tincture from the cannabis by turning up gravity 1000x, you loose a fair amount of solvent (tincture! ie cannabinoids) to each (successive) batch of biomass.
ignoring those losses for the moment, the amount of cannabis you can extract with a given amount of solvent (not actually it’s saturation point, but the point where you decide it’s not worth it to leave so much behind) varies widely with temperature.
I’ve heard tell of 10x more at rm temp than at -40C. haven’t gotten to confirm yet.
at -50C I was getting essentially the same efficiency at 1lb/gal as 3lb/gal. that’s with CBD biomass at 10-12%. knowing how far I could push that without loosing extraction efficiency (or optimizing where i wanted the cutoff to be) would require analytics not currently onsite.
playing with different material at the moment.
starting a 1lb/litre and working my way up.
