Eu não sei se ao ar livre seria o melhor lugar para armazenar seus enlatados domésticos. Mesmo em um gabinete isolado, que o sol não bate, a temperatura no gabinete pode subir no verão acima dos níveis recomendados. Além disso, a umidade pode enferrujar suas pálpebras (e bandas, se você deixá-las ligadas).

Label and date the jars and store them in a clean, cool, dark, dry place. For best quality, store between 50 and 70 °F. Also for best quality, can no more food than you will use within a year unless directions for a specific food provide other advice.
Do not store jars above 95° F or near hot pipes, a range, a furnace, in an uninsulated attic, or in direct sunlight. Under these conditions, food will lose quality in a few weeks or months and may spoil. Dampness may corrode metal lids, break seals, and allow recontamination and spoilage.
Accidental freezing of canned foods will not cause spoilage unless jars become unsealed and recontaminated. However, freezing and thawing may soften food. If jars must be stored where they may freeze, wrap them in newspapers, place them in heavy cartons, and cover with more newspapers and blankets.
