Hey there, mustard fans! The debate over whether or not to refrigerate mustard has been going on for ages. Some people swear by storing it in the fridge, while others say it’s perfectly fine to keep it at room temperature. So, what’s the real story?

Let’s dive into the two sides of this condiment conundrum.

Why Some People Believe Mustard Should Be Refrigerated

Those who argue in favor of refrigeration believe that it can help preserve the freshness of the mustard and prevent it from spoiling. In addition, refrigeration can slow down the growth of microorganisms that can lead to foodborne illness.

According to food safety experts, storing mustard in the refrigerator is a good way to prevent bacteria growth and spoilage. This is especially important if you don’t use your mustard very often, or if you’ve had it for a while.

Why Some People Believe Mustard Doesn’t Need to Be Refrigerated

On the other hand, there are those who argue that mustard can be safely stored at room temperature. Some people point to the historical and cultural reasons for storing mustard this way, while others argue that mustard has natural preservative properties that make refrigeration unnecessary.

Basically, if you use your mustard within a reasonable amount of time, refrigeration isn’t necessary. Also keep in mind that many artisanal mustards are sold at room temperature and can be stored that way at home as well.

The Verdict

So, who’s right? Ultimately, it depends on your personal preferences and how quickly you go through mustard. If you use it frequently and finish it quickly, room temperature storage is probably just fine. However, if you don’t use mustard very often or you’re concerned about food safety, refrigeration is the way to go.

It’s also worth noting that some types of mustard may benefit more from refrigeration than others. For example, mustards that contain white wine or other ingredients that can spoil quickly may be better off in the fridge.


At the end of the day, there’s no right or wrong way to store mustard – it’s really up to you. The most important thing is to make sure you’re enjoying your condiment in a safe and tasty way. Try experimenting with different storage methods to see what works best for you, and remember: whether you prefer your mustard chilled or at room temperature, it’s all about the flavor!
