Storage Guidelines

Commercial storage guidance for mild or sweet dry bulb onions. Storage life depends on initial quality, maturity, cultivar and handling; this is not a household shelf-life guarantee.

Mild and sweet onions keep for a much shorter time than pungent onions, even in optimal cold storage. Highest freezing point: -0.8°C. Source: USDA Agriculture Handbook 66 (rev. 2016).
