unopened pantry6-18 months (or until 'best by' date)
Signs of Spoilage
Bulging lid or can, leaks, rust on can, foul or off-odor upon opening, cloudy brine (if visible through packaging) that wasn't previously cloudy.
How to Check
Visually inspect the packaging for any damage, swelling, or leaks. Check the 'best by' or 'expiration' date. If the container appears compromised or is past its date, discard it without opening.
Storage Tips
Store in a cool, dark place away from direct sunlight and heat. The brine and pasteurization process make these olives very stable when sealed.
opened fridge2-4 weeks
Signs of Spoilage
Mold growth (white, green, black fuzzy spots) on the olives or surface of the brine, noticeably slimy texture, excessive cloudiness or sliminess of the brine, strong sour, yeasty, or putrid off-smell.
How to Check
Visually inspect for mold or discoloration. Use a clean spoon to gently move olives and check the brine's clarity and consistency. Smell the olives and brine for any unusual or unpleasant odors (a slight fermentation smell can be normal, but a strong sour or off-putting smell is a bad sign). Touch test: if they feel excessively slimy or mushy, they're likely spoiled.
Storage Tips
Always keep the olives submerged in their brine; this is crucial for preventing mold and bacterial growth. Use clean utensils each time you retrieve olives to avoid introducing contaminants. Ensure the lid is tightly sealed after each use. Discard immediately if any signs of mold or off-odor are present, even if within the recommended timeframe.
freezer6-8 months
Signs of Spoilage
Severe freezer burn (dry, discolored spots), off-smell after thawing, extremely mushy or unappetizing texture that makes them unsuitable for consumption, even in cooking.
How to Check
Visually inspect for excessive freezer burn. After thawing, smell for any off-odors. The texture will be softer than fresh olives; if it's completely disintegrated or extremely mushy, they may not be suitable. Taste test a small piece if visual and smell checks pass, but only if you are confident they are safe.
Storage Tips
Drain the olives from their brine before freezing. You can freeze them whole or chopped. Spread them in a single layer on a baking sheet to freeze individually, then transfer to an airtight freezer-safe bag or container to prevent clumping and freezer burn. While safe, freezing can alter the texture, making them softer. They are best used in cooked dishes (like stews, sauces, or baked goods) after thawing, rather than as a fresh garnish.
