It looks like it could keep quite well for up to 6 months in the fridge. If you wanted more storage life, you could use dried onions and garlic, and add a bit more vinegar, which would be soaked up by the dried veggies.

With lots of vinegar and no oil, I would keep it a while too. But I'm sure you could freeze it. I don't believe freezing has any effect on capsaicin (the compound that makes peppers hot).

Thanks for the info! That's good news :) I've started adding hot sauce to my cheese sauce for mac-n-cheese but it's still going to take us awhile to get through it. I feel better giving it out as gifts with telling them how long it should keep. Thanks again!
