Storage and Shipping

Vidalia onions have a fairly short harvesting season, but simple modification of our natural atmosphere “puts the onions to sleep” and makes them available into early fall.

Taking a page from the apple industry, the Vidalia industry adapted Controlled Atmosphere (CA) storage technology.

With CA capabilities, Vidalia onions can be stored for several months in an atmosphere where the levels in normal breathing air are adjusted to 92% nitrogen, 5% carbon dioxide and 3% oxygen and the air temperature is maintained at approximately 33 degrees with 70% humidity.

As soon as the market is supplied, “overage” starts going into long-term storage, from which onions will be retrieved as needed for the next several months.

By rendering the harvested onions dormant, controlled-atmosphere (CA) storage makes it possible to enjoy fresh onions through early fall.
