I just received 2 250 gram boxes of Samuel Gawaith tobacco that were vacuum sealed by the seller, so I did some research about the pros and cons of leaving it as is, or jarring it. Well I found the answer to this topic that has been discussed on here sometimes. I will definitely jar it as vacuum sealing stops aging from happening
