Not just terpenes but yes terpenes.
No, No matter what you do with them short of co2 extraction all you are going to get is tar, so no I do not bother with freezing them. I used to just keep them in a gallon zip-lock bag on the work bench. A opossum decided it like to eat them and would sneak into the garage if I left the walk door open and eat them - ALL of them. Now I put them in jars. I think the opossum got hit by a car last month as there was a dead one in the main street not to far away. I know she had babies last year so they are probably still around.
