Cold Ethanol Extraction Data

Are there any references or rules of thumb that show extraction efficiency vs temperature?

For instance: -60* or colder is 85%, -60-40 is 90% and anything greater than -40 is 98%

I run 6.5 gallons though 3000g at temps ranging from -76 to -86 and usually leave a little over 1% of THC behind. I do 5 quick washes with 5 minute soak times.

It will depend so much on input (potency, dryness, grind) that you’re mostly on your own…which is why I recommend In House analytics early rather than late
