Keep potatoes in a cool, dark, well-ventilated place such as a pantry or cabinet. Avoid high temperatures such as next to appliances or under the sink, and keep potatoes away from too much direct sunlight (no countertops).
Do not refrigerate or freeze fresh potatoes before cooking. Colder temperatures lower than 50 degrees cause a potato’s starch to convert to sugar, resulting in a sweet taste and discoloration when cooked.
There is no need to store your potatoes in a bag; you can store them loose. If you store potatoes in a bag, make sure there are holes so the potatoes can breathe. Wait to wash your potatoes until you’re ready to cook them, as dampness will lead to early spoilage.
