A root cellar is an underground area of a house or an outbuilding where root vegetables or other food items can be stored at a specific temperature and humidity. Many people use root cellars to store items such as potatoes, onions, apples, carrots, squash, and beets. Root cellars can be especially helpful if a homeowner does not have consistent access to a refrigerator or freezer.
If you are considering using a root cellar to store your food, it is important to understand that the ideal root cellar temperature and humidity vary depending on the type of food that is being stored. For example, fruits, such as apples and pears, are best stored at 32-40°F (0-4°C) with a humidity of 85-95%. On the other hand, root vegetables, such as carrots and potatoes, prefer temperatures of 32-40°F (0-4°C) with a humidity of 90-95%.
It is important to note that these temperature and humidity levels can be tricky to maintain, especially since the temperature in a root cellar can vary greatly depending on the temperature outside. Homeowners often use a combination of blankets, fans, and thermometers to regulate the temperature in a root cellar. The blankets will help keep the root cellar warm during cold winter months, and the fans will help keep the air circulating. Thermometers should be used to monitor the temperature of the root cellar to make sure that it stays within a safe range.
In addition to regulating the temperature and humidity of a root cellar, it is also important to keep the area clean and free of pests. This can be done by regularly sweeping the floor and making sure that any food items are stored in air-tight containers. It is also important to check the root cellar frequently for any signs of pests, as this could affect both the taste and safety of the stored food.
Overall, root cellars can be an effective way of extending the shelf life of food items. Homeowners should make sure to understand the ideal temperature and humidity for the food they plan to store, as well as take the necessary steps to keep the area clean and pest-free. A properly managed root cellar can provide a great way to safely store food items for months at a time.
