Most canned goods are fine for several years but it all depends on the instructions that were used to preserve them and the type of processing used. In other words if a safe amount of vinegar (at least 50%) was used and the jars were properly processed in either BWB or pressure canner they will last much longer than those made with insufficient vinegar and/or not processed.

Don't know where you got the impression that 1 year was all they would good for? But year old peppers should be fine if done properly. We are currently eating potatoes canned in 2009, pickles from the same year, tomato juice from 2010 and green beans from 2010. 5 years old is my personal limit but others use even longer limits.

Thanks, Dave!

I thought I read somewhere that 1 year was the limit. I'm glad to know that's not the case. I'd hate to have to throw out canned goods I didn't get to within a year!

I used this recipe, so in terms of the recipe/processing they should last just fine.

Is the residue on the threads of the jar anything to be concerned about, given that the jars are sealed and not leaking?

I just opened a jar of hot peppers in the cold cellar 2010 they are perfect
