How to Store Ketchup

Keep unopened bottles of store-bought ketchup in a cool, dark place, away from heat or direct sunlight.

Once the bottle is opened, you should refrigerate it to maximize shelf life. Of course, you can leave it at room temperature, but it keeps quality for only a month this way, instead of 6 to 12 months.

Homemade ketchup should also be stored in the refrigerator, in a tightly sealed container.

When using a utensil to get ketchup out of a glass bottle or jar,make sure it’s clean.

Be careful to keep the bottle cap clean, to prevent contamination and possible mold growth. Simply wiping any buildup off of the cap, and making sure it’s dry before replacing on the bottle should be enough to keep contamination at a minimum.

If you tend to store ketchup for a really long time, consider storing it upside down to retain quality for a bit longer.

How Long Does Ketchup Last?

Ketchup is one of those products that last for a considerable amount of time. This period is indicated by a “best by” or “best before” date printed on the package.

In most foods – including ketchup – a “best by” date is an estimate from the producer that a particular product retains its prime quality when properly stored and handled. Hence, it is highly recommended to consume it before this date.

However, ketchup may stay edible beyond its “best by” date. But, you may expect a slight change in flavor or taste. Unopened bottles of ketchup can last for half a year to a year after its recommended date. Check for spoilage signs before use and discard the ketchup if you’re in doubt.

Once opened, ketchup retains its freshness for around one month when kept at room temperature. But, with continuous refrigeration, ketchup stays fresh for around 6 months.

Homemade ketchup has a limited shelf life. It largely depends on the recipe, quality of the fresh ingredients, and preparation method. When kept chilled, homemade ketchup can last up to one month. Consider canning the ketchup to prolong its shelf life up to a year.

How To Tell if Ketchup Has Gone Bad?

Although ketchup can last pretty long, it can spoil, so you should check for the signs of spoilage before using the ketchup. It won’t be hard to tell if your ketchup has gone bad. A watery liquid in the ketchup will separate from thicker liquid over time, but the ketchup will still be safe to consume. You can simply shake the bottle and everything will be fine. But, if the liquid separates out too much from the tomato paste it is a sign that your ketchup is spoiled.

Also, if you notice that the taste of your ketchup is different it means that it has gone bad. If spoiled, ketchup will also change in color and it won’t have a bright red color anymore. It will probably become dark brown. It is also possible that your ketchup smells sour and this is one more sign that your ketchup has spoiled.

What Is the Shelf Life of Ketchup?

Although ketchup is an acidic product, it spoils after a certain period of time. But, we can say that the shelf life of ketchup is quite long.

A best by date is usually 15 months from the date of the ketchup production.

If ketchup is unopened, it can last 1 or 2 years beyond a date stamp, if you provide proper storage conditions. But, when you open the bottle of ketchup, it can last at room temperature for about a month, but sometimes it lasts only a couple of days. If you store opened bottle of ketchup in the pantry it will last about two or three months.

If you keep it in the fridge its shelf life will be much longer. If opened bottle of ketchup is refrigerated, it can last for up to half a year, if it is stored properly.

As you can see, it is always better to store ketchup in a cooler place.

Should You Refrigerate Ketchup?

Storage Practices

Make sure your ketchup is always sealed tight when not in use. That’s the most important thing.

If you want to up your ketchup storage game a bit, there are some options.

First, you can store the bottle upside down. This way, less air gets into the sauce, which slows down oxidation. As a result, the condiment’s quality deteriorates a bit slower.

(Some ketchup bottles are designed to be stored on the cap and sometimes even have the label printed upside down.)

Next, try to keep the tip clean.

Wiping it clean with a dry paper towel after every use would be ideal, but we all know that’s not going to happen. Instead, try to do that every couple of uses, so that the buildup doesn’t become dry and gross.


If the tip is super dirty and a dry paper towel won’t cut it, dampen the towel with a bit of running water. Once the tip is nice and clean, remove any remaining moisture with a kitchen towel.
