You’ll find the Best By Date stamped on the shoulder of the jar, on the glass itself, near where it curves into the lid. Just above this is a production code.
By the way, we have a 24-month date on our cut products, and a 30-month date on everything else. Because of the way we make our pickles they do not spoil over time. They may just get dark and soft. If you have a jar that’s past its Best By Date, there’s no harm in trying it for taste and texture. If it still tastes fine, enjoy!
