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!!!!
Either way is fine. If you keep the glass jars full this also helps to exclude air. And contrary to popular belief the powders will oxidize slower than the cut herbs since they will pack tighter and exclude more air.
The advantage of the vacuum packing is for the cut herbs since this will remove the air and take up less space. Therefore I would use the vacuum packing for the cut herbs and jars for the powders.
