Shelf life for different products will vary. Reese takes pride in having delicious products and always encourages consumers to look for the “Best By Use” date on all packaging to ensure the best quality! Products that are canned or jarred can be stored safely for up to two years. If there is no sign of a broken seal, expansion of the packaging or any other physical damages, the product can be consumed. However, flavor can be altered if stored too long in certain conditions, so trust your palate if something doesn’t taste right!
