I am not trying to be difficult here, so forgive me for asking... would it be advantageous to vacuum seal them and NOT freeze them, or would the glass jar be the best way? I have m-a-n-y glass jars, so storage like this would not be a problem. I was just wondering if keeping air away would keep their potency for a longer period of time. I am new to storing herbs, so need experts to guide me!!! Thank you!!!!
