The general rule: 12 to 24 months
A properly sterilized jar with an intact seal keeps between 12 and 24 months in a cool, dark and dry place. Beyond that, a well-sealed jar rarely becomes dangerous overnight — but colour, texture and flavour slowly decline. The date on the label is therefore above all a quality marker.
Shelf life by type of preserve
- Jams and high-sugar preserves: 12 to 24 months
- Fruits in syrup and compotes: 12 to 18 months
- Tomatoes and tomato sauces: 12 to 18 months
- Low-acid vegetables (green beans, carrots…): about 12 months
- Cooked dishes, meat and fish: 6 to 12 months
- Lacto-fermented vegetables: several months, ideally in cool storage
The right storage conditions
Light, heat and humidity are the three enemies of your jars. Aim for a dark room with a stable temperature between 10 and 20 °C — a cellar, a pantry or a cupboard away from the oven. Avoid damp rooms, which rust lids, and big temperature swings, which weaken seals.
When a jar must be thrown away
Never taste a doubtful jar. Discard it if the lid is bulging or no longer sealed, if liquid spurts out on opening, if the smell is unusual, if you see mould, or if a brine that should be clear has turned cloudy. When in doubt, throw it out.
Label, date and rotate your stock
Write the content and the month and year of canning on every jar, store the newest batches at the back and always consume the oldest first. An up-to-date inventory tells you at a glance what is left and what should be eaten soon — that is exactly what Jarrito does for you, batch dates and storage locations included.
