Need some advice on long term aging!

Big D scores!! Nice job, man. I'm sure you'll be very happy with it.

In answer to the question of sealing a mason jar without the Foodsaver. Yes, you can.

You have to heat it up with boiling water inside. Let the glass heat up and boil the lid in water at the same time. Dump the water out. Put the tobacco in quickly, put the lid on, and secure the ring. When the glass cools, and the air inside cools, it creates a vacuum. You'll know if you did it right when you press on the lid, and it doesn't pop up.

There is some concern that you can "cook" the tobacco with heat while doing this process. I've only done it this way a few times, and didn't have a problem. Maybe if I got the glass hotter it would have happened, I dunno. The glass cools down fairly quickly.

Best of luck.
