EtOH Recovery and terpenes

I am recovering EtOH post cryo extraction. Although it is low temp under vacuum I am wondering if I am stripping off the terpenes at the same time?

I have not been able to do the smell test yet but figured I’d see if anyone has looked at this yet.

Thanks!

you are most certainly boiling off some of your mono-terpenes. probably some of the heavier ones too. it comes with the solvent.

you may be able to tip things a little more in your favour using pH, but I don’t know the details of that particular trick.

thanks thats what I figured. It would be a miserable mess trying to remove terps from gallons of alcohol…
