Storing olives once opened cannot be reduced to a single universal number of days. What almost all cases do share is the underlying logic: once the pack is opened, the stability provided by the seal and the packing process ends, and the business becomes responsible for keeping the product in good condition. For that reason, the reference for setting shelf lives and temperatures must always be the manufacturer’s information, supplemented by the business’s own food safety management system.
For a purchasing, kitchen or quality manager, this has direct consequences: the format bought, the rate of consumption and the way the product is handled determine how many olives, pickles or skewers are served safely and how many end up being discarded. The sections that follow set out the decisions worth taking before and after opening a professional pack.
While the pack remains sealed, the product is protected from contact with the air, from handling and from microorganisms in the environment. Its shelf life is expressed by the date on the label, which refers to the unopened product stored under the stated conditions.
On opening, several factors change at once: the product comes into contact with the air, utensils and hands are introduced, the temperature rises during service, and the ratio of fruit to liquid may change as pieces are removed. None of these factors is serious on its own, but they accumulate over the days. For that reason, once a pack is open, the printed date is no longer the reference and the specific criteria for use must be applied.
Regulation (EU) 1169/2011 on food information states, in Article 25, that where foods require special storage and/or use conditions, those conditions must be indicated and that, to enable appropriate storage or use once the package has been opened, the conditions and/or the time limit for consumption are to be given where appropriate. The text can be consulted on EUR-Lex.
The phrase “where appropriate” matters: not every product carries the same indication or the same duration. That information may appear on the label or in the technical data sheet, and it takes precedence over any general rule. The article How to read a Technical Data Sheet for olives and pickles explains which fields to review; the one that matters here is what the manufacturer says about the product once opened.
Anyone searching online for how long opened olives last will find very different answers depending on the source. That disparity is precisely the proof that the time limit depends on the type of preparation, the variety, the dressing, the heat treatment, the pack and the producer’s instructions.
For a professional business, applying a generic figure to every product would be a mistake. A green olive in brine, an olive dressed with garlic and oil, a gherkin, a piparra or a gilda with anchovy and cheese are different products, and each may have its own conditions. The operating rule is simple: the shelf life and temperature are taken from the data sheet for each product, not from a single rule covering the whole catalogue.
Whatever the specific time limit, there are handling practices that reduce risk and apply to almost any pickled product. They are worth reviewing with the team and adapting to the instructions for each product:
The format affects how the product is stored once opened. Glass and PET packs can usually be closed again, so they can go back into the cold room after each use, provided the closure is secure and the product remains covered.
With tins, the usual recommendation is not to leave leftover contents in the metal container. Consumer, the Spanish consumer organisation’s food safety service, notes that contact between the food, the metal and oxygen can cause rust spots in an open tin, and therefore advises transferring leftovers to another container. In a professional kitchen, this practice requires a clean, food-grade container with a lid, labelled and marked with the opening date, while also following the manufacturer’s information.
The 5 kg and 10 kg PVC buckets, the 2.5 kg and 5 kg tins and the T-2.5 PET and T-4.5 PET jars in the Olives GARCÍA range are used for high consumption volumes. The larger the pack, the longer it stays open and the more often it is handled, so the usage plan should allow for how many days it takes to finish it. The capacities and products for each format can be found in the article on olive, pickle and skewer packaging formats.
Skewers combine different ingredients in a single piece: olives, piparras, anchovy, cheese, octopus or other components. This means that storage depends on the most delicate ingredient and on the medium in which they are presented.
For that reason, they should not be treated in the same way as olives in brine. For skewers, gildas and banderillas, it is advisable to ask the supplier for the specific storage and usage instructions once the pack is opened, rather than applying by analogy the time limits for a simple pickle.
The manufacturer’s date refers to the sealed product. On opening, the business must decide how long it can be used, and that decision forms part of its food safety management system. A sensible procedure has four steps:
The time limit should not be based solely on popular articles, because they do not take into account the recipe, the pack or the treatment of each product.
Labelling the open pack is the simplest and most effective measure. It shows when the pack was opened, who opened it and until when it can be used. It is advisable to include:
With these labels, FEFO (first expired, first out) rotation can be applied: the product with the nearest time limit goes first, regardless of when it arrived. Applying it to open packs prevents a jar forgotten at the back of the cold room from exceeding its time limit, and reduces wastage.
Beyond the time limit, there are situations in which an open pack should be withdrawn: visible changes in the colour, smell or texture of the fruit, cloudy liquid or liquid with an unusual appearance, packs with a badly closed lid, product not covered by the liquid, or doubt about how long it has been outside refrigeration or whether it has been handled with unclean utensils.
When the team cannot guarantee the condition of the product, the prudent rule is to discard it and record it. The cost of a withdrawn unit is always lower than the risk of serving a product in poor condition.
Often the storage problem starts with the purchase. A 10 kg bucket is efficient for a business with high daily consumption, but it generates wastage in one that takes three weeks to use it. The question the buyer should ask is how many days are needed to finish the pack once opened, and to compare that with the time limit set for that product.
If consumption is low or irregular, a smaller format may be preferable, even if its cost per kilo is slightly higher. If it is high and stable, large formats mean fewer openings and less handling. Each option should be assessed using real consumption data, not estimates.
It depends on the product, the preparation, the pack and the manufacturer’s instructions. There is no universal time limit; the label or the technical data sheet for each product should be consulted.
In general it is advisable to keep them refrigerated and closed, but the specific temperature and conditions must follow the product’s instructions and the business’s food safety plan.
This is not advisable. It is part of the preservation and helps keep the fruit covered. If the level drops, consult the supplier before topping it up.
It is usual to recommend transferring the leftovers to a clean, food-grade container with a lid, and labelling it with the opening date. The manufacturer’s information should be followed.
This is not advisable, even if they are the same variety, because traceability is lost and different opening dates are combined.
Not necessarily. They contain other ingredients and their storage depends on the composition. Specific instructions should be requested for each product.
The storage of olives, pickles and skewers does not start in the cold room: it starts with the choice of format, continues with the manufacturer’s information and ends with a clear procedure for labelling, rotation and withdrawal. A business that has those three elements serves a more consistent product and wastes less.
If you are considering which product and format best suit your business’s rate of consumption, contact Olives GARCÍA and tell us the product, the channel, your estimated weekly consumption and the format you use. With that information, we can suggest the option that reduces unnecessary openings and makes the product easier to control once opened.
