You open the fridge to find a jar of relish that has been sitting there since the last time you cooked. It smells nice, but I don’t know how old it is. Does relish spoil?
Short answer: Yes, relish does go bad, but it is one of the most long-lasting seasonings on the market. Store-bought relish has a long shelf life if unopened, and once opened, it can be stored in the refrigerator for up to one year. Homemade relish is another story.

Important points
- relish goes badHowever, due to its high vinegar and sugar content, it is one of the most stable seasonings in your refrigerator.
- Unopened commercial relish Stays in top quality for up to 2 years in your pantry.
- Opened relish It should be kept refrigerated and will retain its best quality for up to a year.
- sweet relish and dill relish There is no significant difference in shelf life. Both use vinegar as the main preservative.
- homemade relish If not canned, it will only last for 1-2 weeks in the refrigerator. Properly canned, homemade relish will keep for 6 to 9 months.
- bulging lid What you see on an unopened bottle is the most important sign of spoilage to check for before opening.
How long does Relish last?
Relishes belong to the same family as pickles. Both consist of chopped vegetables soaked in a solution of vinegar, salt, and, in the case of sweet relish, sugar. This combination creates a low pH environment that makes it very difficult for bacteria and mold to survive. Therefore, commercially available relishes have a very long shelf life.
| type | Pantry (unopened) | Refrigerator (opened) |
|---|---|---|
| Sweet pickled relish (for commercial use) | up to 2 years | up to 1 year |
| Dill relish (commercial) | up to 2 years | up to 1 year |
| Corn or pepper relish (commercially available) | up to 2 years | up to 1 year |
| Homemade relish (not canned) | Not recommended | 1-2 weeks |
| Homemade relish (properly canned) | 6-9 months | Within 1 year after opening |
Quality estimates are based on proper storage. Regardless of date, always check for signs of spoilage before using. Guidelines are consistent with USDA Food Keeper Recommendations.
Does sweet relish last longer than dill?
Sweet and dill: no meaningful difference
This is one of the most frequently asked questions about relish storage, and the answer may surprise you. From a food safety perspective, sweet relish and dill relish have approximately the same shelf life. Both mainly use the acidity of vinegar as a preservative. Sweet relish also contains an additional preservative, sugar, but the difference in actual shelf life between commercial varieties is negligible.
What you might notice a real difference in is the quality of the flavor over time. Dill’s aromatic compounds are more volatile than sugar or the simple sweetness of cucumber, so an opened jar of dill relish can taste noticeably bland after a few months compared to sweet relish. This is a quality observation, not a safety observation. Both have a basic acidity and can be safely stored year-round during refrigeration.
Signs that the relish has gone bad
when to throw it away
Bulging or dome-shaped lid (unopened jar): This is the most important check before opening a jar of relish. If the lid is uneven and bulges up or slightly concave, this indicates pressure buildup inside, a sign of fermentation or bacterial activity. Please do not open it. Discard the entire jar.
Type: If there is visible mold, fuzzy growth, or a film on the surface of the relish, discard it immediately. Do not skim around. Mold can penetrate beneath visible surfaces.
Foul or strange odor: Depending on the type, fresh relish can have a tangy, vinegary, slightly sweet, or herbal flavor. If it smells rotten, has a doughy, yeasty smell, or has an unpleasant sour smell that is distinctly different from the taste of regular vinegar, throw it away.
Slimy texture: If the relish is unusually slimy or has a slimy consistency, it indicates that the structure of the vegetable is broken and it is rotten.
What is not a sign of corruption:
color change This is the most common misinformation. Relish darkens over time due to oxidation. This is the same process that turns cut apples brown. It’s usually still okay if the green relish turns olive or tan. Check the smell and taste before throwing away just the color.
liquid separation It’s normal. Over time, the brine and solids will separate. Stir quickly to restore texture. If you stir it and it comes back to normal, the taste is fine.
How to store relish correctly
Storage best practices
Refrigerate after opening. Unopened store-bought relish can be stored, but once the seal is broken, store it in the refrigerator. According to FDA Safe Food Handling GuidanceOpened condiments, such as relish, should be kept refrigerated to maintain quality and prevent spoilage.
Keep the original jar tightly closed. Relish is best stored in its original glass bottle. Always make sure the lid is fully tightened after each use to minimize exposure to air and prevent refrigerator odors from transferring.
Always use clean and dry equipment. Food particles and moisture from used spoons can get into the jar, accelerating deterioration. Pour the relish or use a clean spoon each time.
Store unopened jars in a cool, dark pantry. Heat and light will gradually degrade the quality even through a sealed bottle. It is effective to place the kitchen cabinets away from the stove.
Label the jar with the date it was opened. Commercially available relishes all taste similar after being stored in the refrigerator for several months. Having a tape with the opening date on it takes all the guesswork out of it.
Homemade relish is a separate category
Homemade relish made with fresh cucumbers, peppers, onions, and vinegar is much more perishable than store-bought relish if it is canned without proper heat treatment. Commercially available relish undergoes a high-temperature treatment during production that kills bacteria and creates a sealed, sterile environment. A batch made at home and stored in a jar in the refrigerator has no such protection.

Refrigerate your homemade relish immediately and use it within 1-2 weeks. If you want to preserve it longer, proper water bath canning is the right way to go. Properly processed and sealed in sterile jars, homemade relish can be stored for 6 to 9 months in a cool, dark place and up to 1 year if refrigerated after opening. of CDC Food Safety Guidelines Also, resources like the National Center for Home Food Preservation offer reliable canning instructions, especially for relish.

FAQ
Can I use relish past its expiration date?
For unopened commercial relishes, yes in most cases. The expiry date is an indicator of top quality, not safety. Properly stored and undamaged jars will remain safe and flavorful even after the expiration date. Open it, check for any bulges in the lid, smell and taste. If everything is fine, you may be able to use it without any problems. If it is many years old or shows signs of decay, throw it away.
My relish turned black in the jar. Are you still okay?
Probably so. A change in color is the most common but unreliable indicator of relish spoilage. Vinegar-based products oxidize and darken over time, and the vegetables themselves naturally change color. First, check the smell. If it smells the same as usual, taste a small amount. If the taste is flat or slightly lacking in vibrancy, this is a sign of poor quality, not a safety concern. Mold, slime, and bad odors are signals of actual rot.
Can I get sick if I taste it?
Eating spoiled relish can cause indigestion. Commercial relish is highly acidic and therefore resistant to most harmful bacteria, but mold and yeast can develop over time, especially after opening. Do not eat if the lid of the jar is bulging, mold is visible, there is a strange odor, or the texture has changed. For properly stored relish with no signs of spoilage, the risk is very low, even if it is past its expiration date.
Can you freeze relish?
Yes, but considering the long refrigerated shelf life of the relish, it’s rarely necessary. Freezing is the best option for homemade relish that you want to keep longer. After thawing, the texture of the vegetables may become slightly soft, which will affect the quality but is not a safety issue. Freeze it in small airtight containers or ice cube trays for easier portioning. Thaw in the refrigerator before use.
Does relish need to be refrigerated after opening?
yes. Although commercially available relish is highly acidic, which technically means it won’t spoil quickly at room temperature, refrigerating it after opening is the standard recommendation and will greatly improve quality. If an opened jar is left at room temperature, its color, texture, and flavor will deteriorate much faster than a jar kept cold. For a complete storage guide, see the related post.
