Expiration & Storage Tips
When does red potato expire?
Unopened: Potatoes are harvested and stored in unopened bags so this doesn't apply. Shelf guidelines after purchase are about 3 weeks at normal room temperature away from light and about 2-3 months in cool places, like a basement.
After Opening: As soon as potatoes are exposed to air they begin to dehydrate, so store them in a dark, cool, well-ventilated place where they'll last for up to 3 weeks.
Frozen: Freezing isn't typically recommended for raw red potatoes as it can seriously alter their texture and taste. If using in a dish such as a stew, they can be frozen as part of the cooked dish.
Compared to Printed Date: Potatoes don't come with a printed expiration date, they’re best eaten within 3 weeks of purchase to enjoy their best taste and nutritional value.
How do you tell if red potato is bad?
Potatoes gone bad are simple to identify. They might have green spots, which should be cut off before consumption as they contain toxins. If the potatoes have begun sprouting, they should be used immediately or removed to avoid rotting. A rotten potato may be shriveled and discolored. The worst case is a very foul smell, indicating the potato is not suitable for consumption in any circumstance.
Tips for storing red potato to extend shelf life
• Store in a dark, cool, well-ventilated place to keep them fresh longer. Light and heat will cause your potatoes to sprout sooner.
• Do not store potatoes in the refrigerator. The cold will cause the starch to turn into sugar, affecting the taste.
• Do not wash potatoes before storing; this can quicken spoilage.
• Reserve the plastic bag potatoes come in for other uses. Instead, store them in a breathable paper bag, mesh bag, or cardboard box to increase their lifespan.
• Keep potatoes away from onions, as both release gases that promote the other’s decay.
• Immediately remove and use any potatoes that have started to sprout to prevent the rot from spreading to other potatoes in the bag.
