Storing potatoes in plastic bags is a common practice, but it may not be the best way to keep them fresh for extended periods. Plastic bags can trap moisture, creating an environment that causes potatoes to spoil more quickly. Therefore, it is recommended to store potatoes in a cool, dry, and dark place with good ventilation. This helps prevent sprouting and keeps them fresh for longer. Various alternatives to plastic bags, such as paper bags, baskets, or mesh bags, are suggested to ensure potatoes remain in optimal condition.

Plastic bags can trap moisture, creating a damp environment for potatoes
Plastic bags are not ideal for storing potatoes. Potatoes are plants, and if they are exposed to sunlight, they will photosynthesize and turn green, eventually wrinkling and rotting. Plastic bags can trap moisture, creating a damp environment where potatoes are likely to spoil more quickly. This is because potatoes need air circulation. They are high in water content and need a humid environment, but they also need air circulation to prevent mold and rotting.
The best way to store potatoes is to keep them in a cool, dry place, in something that is not airtight. If you buy potatoes that come in a plastic bag, you should take them out of the bag for storage. A paper bag, a hessian sack, or a basket are all good options that allow plenty of air circulation.
It is also important to keep potatoes in a dark place. If they are stored in a warm, dark place, they will happily send forth sprouts if you don't keep them cool enough. The perfect temperature for storing potatoes is 45°F to 55°F, which is only slightly above refrigeration temperature. Think garages, sheds, cellars, porches, or the coldest, draftiest spot in your kitchen.
It is also worth noting that potatoes should not be stored next to produce like onions, bananas, and apples, as these produce ethylene gas, which can cause nearby produce to ripen and spoil more quickly.

Potatoes need air circulation, so avoid containers or plastic bags
Potatoes are a versatile vegetable with a long shelf life and can be boiled, fried, sautéed, mashed, roasted, baked, or turned into chips, fries, or hash browns. They can be stored for months if stored correctly. However, one of the most common mistakes people make when storing potatoes is failing to keep them cool. Potatoes need to be stored in a cool, dry, well-ventilated place, away from direct sunlight. The ideal temperature for storing potatoes is 45°F to 55°F, which is slightly above refrigeration temperature. Good places to store potatoes include a garage, shed, cellar, porch, or a drafty spot in the kitchen, avoiding hot spots such as next to the oven, on top of the fridge, or under the sink.
It is important to note that potatoes need air circulation, so they should not be stored in containers or plastic bags. Plastic bags can trap moisture, creating a damp environment where potatoes are likely to spoil more quickly. Instead, potatoes can be stored in a paper bag, a small hessian sack, a basket, a cardboard box, or a bamboo vegetable steamer—anywhere that is dark and well-ventilated. If you do store potatoes in the plastic bag they came in, make sure it is well-perforated and that the top is not tightly sealed.
Some people recommend storing potatoes in a single layer on a screen and covering them loosely with burlap or straw in an unheated area of a basement or cellar. This allows for the necessary air circulation while also providing a humid environment, as potatoes are high in water content and need humidity to prevent mould and rotting.
Additionally, it is important to store potatoes away from certain types of produce, such as onions, bananas, and apples, as these produce ethylene gas, which can cause potatoes to ripen and spoil more quickly.

Store potatoes in a cool, dry place, like a pantry or paper bag
Storing potatoes in a cool, dry place is essential to keeping them fresh for longer. While it may be tempting to store potatoes in the plastic bag they came in, this is not ideal as plastic bags can trap moisture, creating a damp environment that causes potatoes to spoil more quickly. Instead, transfer your potatoes to a paper bag, which allows for better air circulation and helps prevent moisture build-up.
The pantry is an excellent location to store potatoes as it typically meets the desired cool and dry conditions. Keep the potatoes in the original packaging when storing them in the pantry, ensuring the bag is not sealed tightly. Alternatively, transfer them to a paper bag or mesh bag, a basket, or a well-ventilated container. Avoid storing potatoes in the open on the countertop, as sunlight will cause them to turn green and eventually wrinkle and rot.
If you don't have a pantry, there are other storage options to consider. A closet or kitchen cupboard is a suitable choice, providing a cool, dry, and dark environment for your potatoes. Basements and garages can also be good alternatives for storing potatoes, as long as they are not too cold or damp. Keep the potatoes off the floor and consider using shelves or storage containers to improve air circulation.
In addition to maintaining a cool and dry environment, it is essential to ensure proper ventilation in the storage area. Potatoes release carbon dioxide and water vapour, so adequate airflow will help prevent moisture build-up and mould growth. Avoid storing potatoes in sealed containers or plastic bags, which can restrict airflow and promote spoilage. Instead, opt for paper bags or baskets, which allow the potatoes to breathe and stay fresh for longer.

The ideal temperature for storing potatoes is 45°F to 55°F
Storing potatoes in plastic bags is not ideal. Plastic bags can trap moisture, creating a damp environment where potatoes are likely to spoil more quickly. Plastic bags can also allow potatoes to see sunlight, which will cause them to turn green and eventually wrinkle and rot. Potatoes stored in plastic bags can also sprout more quickly.
Instead, potatoes should be stored in a cool, dry, dark place with good ventilation and out of direct sunlight. A paper bag, basket, cardboard box, or large bowl are ideal for storing potatoes since they allow for plenty of air circulation. If storing in a plastic bag, it should be well-perforated and not tightly sealed.
It's also important to avoid storing potatoes with produce such as onions, bananas, and apples, as these produce ethylene gas, which can cause potatoes to ripen and spoil more quickly.

Avoid storing potatoes in the fridge or freezer
Storing potatoes in plastic bags is not recommended as they tend to go bad quicker. Potatoes are best stored in a cool, dark, and humid environment with good air circulation. A paper bag or a potato bag made of breathable material is ideal for storing potatoes. They can also be wrapped in tin foil and stored in a dark cupboard or pantry.
While storing potatoes in the fridge may be common in warmer climates to prevent spoilage, it is not advisable. The ideal storage conditions for potatoes are cool temperatures, not cold, and a dark environment. A cool, dark cupboard or pantry is a perfect place to store potatoes and will help extend their shelf life.
Additionally, it is important to separate potatoes from onions as the gases emitted by onions can cause potatoes to sprout prematurely. Keeping potatoes away from direct light and in a well-ventilated area will help prevent sprouting and prolong their freshness.
In summary, to ensure the best storage of potatoes, avoid plastic bags, refrigeration, or freezing. Instead, opt for a cool, dark, and dry environment with good air circulation, such as a basement, cellar, or dark cupboard, and separate them from onions to maintain their freshness and quality.

The perfect temperature for storing potatoes is 45°F to 55°F, which is only slightly above refrigeration temperature.
Warm and dark conditions are close to a potato's natural growing conditions, and they will quite happily send forth sprouts if kept in such an environment.
The extra-cool temperature can potentially prove harmful by turning the vegetable's starch into sugar, giving them an oddly sweet flavour and an unappealing brown colour when cooked.
