Why Does Relish Go Bad?

Even though relish contains vinegar which may act as its natural preservative, relish can still go bad. Why?
That’s because the acidity levels of vinegar decrease over time. When it does, there will be room for bacteria to grow in the relish, which will cause it to spoil, rendering it unsafe for consumption.
How Long Does Relish Last?
Since it contains vinegar, you can expect relish to last long—as long as it’s unopened. However, its shelf life will be a lot shorter once it’s opened. This is because it gets exposed to both air and heat upon opening.
To help you determine when you can enjoy relish at its best quality, check out the table we’ve prepared for you below:
Type of Relish | Shelf Life |
Store-bought (Unopened) | 2 years |
Store-bought (Opened) | 1 to 3 months |
Homemade relish | 1 week |
As mentioned, opened store-bought relish will spoil faster than the unopened one.
And if you love making your relish at home, you should keep in mind that it will have a shorter shelf life than the commercial ones. Since it’s less likely that your recipe includes the use of artificial preservatives.
Last but not least, please take note that all the above-mentioned shelf lives are just estimates. These apply only if it has no signs of spoilage.
How Do You Know if Relish Is Bad?
Of course, you would need to check the expiration date first. If it’s been years past the expiry date, you shouldn’t use it. If it’s only months past the expiry date, you should inspect it closely.
The good news is you can easily tell if relish has gone bad. But of course, you need to take the time to inspect it for any of these signs.
The first and most obvious sign would be mold growth which you can see as a fuzzy green or white growth at the surface of the relish. If you’ve seen some, we don’t recommend just simply scooping it out (like most people do) since the relish might have already been contaminated. Instead, throw away the entire jar or can right away.
You might also notice a slimy texture on tit. Yes, we know that relish is naturally slimy. However, it will have a mucilaginous film on its surface when it gets spoiled. If this is the case, you should no longer use your relish.
Another way you can easily tell that it has already gone bad is to check out its smell. If it smells off, sour, or pungent, you should discard it already.
How to Store Relish Properly?
The best way to prevent relish from going bad is to store it the right way. Check out our tips on how you can do it:
1. Place it in a tightly sealed jar.
When it comes to keeping it fresh, the most important thing you can do is protect it from air. You can place it in an airtight container or tightly sealed jar.
Pro Tip: As much as possible, use glass jars and avoid plastic containers with PVC as this can harm your health. (*)
2. Store unopened relish at room temperature.
As long as it’s still unopened, you can store relish at room temperature. Just make sure that it’s placed in a dry, dark, and cool place to protect it from air, heat, and light.
3. Store opened relish in the refrigerator.
Once opened, you should refrigerate the relish to delay the spoiling process.
4. Don’t freeze.
Freezing is the best move if you wish to prolong the shelf life of a food item. Since relish already has a decent shelf life, freezing it won’t be necessary.
Because of this, freezing will no longer be beneficial. It may even do more harm than good since it can change the texture and color of the relish.
