ABV is pretty toasted. Should have very little moisture, if any at all, and seems to keep fine in a closed jar. I've read somewhere that ABV, left to the light and air, will just continue to metabolize THC to CBD/N, and thus becomes a better ingredient for those chasing pain relief and insomnia. So, theoretically, you could just throw it in a container on the counter and maybe shake it occasionally, until you use it. The canna oil I make has never gone "bad" on me. Coconut oil is a natural preservative agent. Essential oils degrade, but keeping it in a dark, tight jar helps slow that down.
