Jars resealed?

[btp79]

In the process of transferring my jarred cellar to a mylar bag cellar, I've run into a number of jars with an obviously stronger vacuum than when originally jarred, and probably an equal number of positively pressured jars that damn near blew the lid off when I removed the ring.

So aerobic fermentation takes place and the air pressure in a jar is lowered.
Aerobic fermentation takes place in a tin and it puffs out.
Why is that?

One uses the sugars and creates gas as a byproduct, the other consumes the free gas in the container and turns it into other stuff. That's a pretty gross oversimplification of the process and I can't remember which one does what, But you can see the same type process in diy wine making. The balloon expands when CO2 and other gas is produced, then contracts again when something else uptakes the gas.

Wonderful thread guys. This noob needs to research this site better. I havent done any cellaring yet but suppose I will sooner or later.

As a side note to this discussion... if you jar your blends at say 5000' ASL or higher, and then move down to a much lower altitude with your jars intact, that will create a great vacuum all by itself. And if your close to SL and move to a much higher altitude the opposite takes effect. I know this from experience. In Santa Fe, at the grocery stores most everything is puffed up because most everything was packaged at a much lower altitude. The blends I jarred at 8000' now have a large vacuum on them just from the move back to Texas.

This is a good piece to read for those interested in what happens to tobacco when you open a tin and jar it and what happens when you don't
