rye bread should ideally not be refrigerated, as the bread will dry out and become stale faster than at room temperature. If you must refrigerate rye bread (eg, due to a lack of pantry storage space or very hot, humid room conditions), the bread will typically last for only about 2-3 days before getting stale.
Does rye bread stay fresh longer?
Bottom line is rye bread has a really nice shelf life, even after it's been sliced and opened. I have had it last several weeks on a repeat basis. It doesn't go bad, moldy or stake in that time. Eventually it all gets eaten no matter how long it's been.
Does rye bread keep well?
To maximize the shelf life of packaged rye bread, keep tightly closed in original packaging and store at room temperature. Properly stored, packaged rye bread will last for about 5 to 7 days at normal room temperature.
