The Ultimate Guide to Storing Onions: Winter Preparation for a 2-Year Shelf Life!


Ideal Conditions: Onions thrive in cool, dark, and dry conditions, with temperatures between 35°F and 50°F (1.7°C to 10°C). Lack a cellar? A garage or a shaded pantry can suffice, provided there is ample ventilation.

Ensure Good Airflow: To prevent mold and rot, onions should be stored in a way that allows air to circulate freely around them. Mesh bags, pantyhose, or homemade onion strings are excellent choices for this purpose.

Separation is Crucial: Since onions emit gases that can accelerate spoilage in other produce, store them away from potatoes and fruits.

Darkness Matters: Keeping onions in the dark prevents bitterness and sprouting. If using translucent storage options like mesh or pantyhose, ensure they're kept in a darkened room.

Routine Inspections: Regularly check on your stored onions, removing any that show signs of spoilage to prevent them from affecting the rest.
