ABV shelf life ?

How long will my ABV remain viable for either cooking or for vaping later a a higher temp (as an emergency stash) ?

My initial sessions are around 356F / 180C ... that goes in a jar to vape later at 365F / 185C ... then retired to a second jar.

I'm wondering how long i can keep this material on hand before it goes bad ...
Thank you :-)

I haven't had my abv tested, but it has retained potency for years kept in mason jars in a dark, cool pantry.

I think as long as it is air tight and kept out of light (just like mj prior to vaping) it can keep for a good long while. My son doesn't even keep his in a jar and has had good results cooking with abv that was left out in the air for months.

It's not going to go bad, maybe ever. Think of it like jerky....pre-cooked, dried, all the moisture content removed. The element that can cause it to go bad (water/moisture) is largely absent. It's almost like wondering when paper will go bad.
