i'm not, we go thru alot of tomatoes but on the other hand, green beans, beets, theres only so many of those we can eat in a year and i keep canning more, yes i do rotate but still have a bunch, i have pear butter thats at least six years old and still good, since we don't eat much bread, no use for the butters i cannedI’m still using tomato juice I canned almost 5 years ago. The lids are nice and tight yet.
