Do Hershey’s kisses go bad? Yes, Hershey’s kisses do go bad, but not as fast as other chocolates that contain dairy. As long as the plastic bag the kisses come in is not damaged or punctured, these chocolate minis can last up to eleven months.

But if you do open the bag, it is best to store them in a ziplock bag. Placing the ziplock bag in the fridge is one way to preserve the kisses. But if you place them back in the pantry after they have been opened, that is fine as well. They just won’t last as long.

Hershey’s Chocolate has Dairy – Why Does it Last So Long?

You may think that because Hershey’s kisses have dairy as part of their ingredients, the kisses will only last two months before going bad. After all, dairy goes bad quickly, and even if there is only a small amount of dairy and nutritious kids, that could certainly speed up the expiration date, right? Well, that would be true if Hershey Kisses didn’t have four types of preservatives to the secret chocolate recipe to keep the kisses stable and prevent the dairy from rotting them from the inside.

But this doesn’t mean that you shouldn’t store the kisses the right way or leave them out on the counter. The preservative protects the kisses from spoiling if stored away correctly.

How to Know if Hershey Kisses have Gone Bad

Although they may be delicious and bite-sized for our enjoyment, Hershey’s kisses go bad just like all other foods. So, if you find a bag of kisses in the back of your pantry or fridge, and you don’t know how long they have been there, you need to know the signs that chocolate has gone bad.

White spots – this is difficult or easy to do, depending on the size of the kisses. When you take some of the Hershey’s Kisses out of bed, see if they have any small white spots. The small white spots mean that the chocolate is turning old and it is not good to eat. If you see a small amount of spots, but you want to double-check and be sure, take a knife and cut the kisses in half. If the inside is turning white, then the chocolate is too old.

Unfading flavor – Hershey kisses are known for its rich chocolate flavor, but its rich flavor is usually the first to go when chocolate turns old. To check the quality of the Hershey Kisses chocolate, place one or two kisses in your mouth and let them sit on your tongue. If you notice I do not have much flavor, then the kisses are too old.

No chocolate smell – along with its rich chocolate flavor, the Hershey’s Kisses also have a fragrant chocolatey smell. To check for a good smell, smell the chocolate from inside the bag. There is no need to take the chocolate kisses out and place them in your hand. Just smell the bag and see if you can take in the smell of chocolate. If there is no smell, do not use them in your baking because they will not taste very good.

How to Store Hershey’s Kisses

Depending on how the chocolate minis are stored and if their bag is open, they can last for a short or long while. Just remember, the less contact the chocolates have with air and moisture, the longer they will last.

In an unopened bag – when you first buy the chocolates and store them in your home, place them in a cupboard or a pantry that doesn’t get any light and humidity, and moisture does not seep in. But if the temperature in the pantry rises above 75F/23.9C, then put the kisses in the fridge, or else they will all melt together. 

In an opened bag in the pantry – After you are finished with the kisses, place the kisses in a ziplock bag and store them back in the pantry. It is a good idea to write the date you opened the bag somewhere near the top, so you don’t use it after a certain time.

In an opened bag in the fridge – If the weather is hot or you have an infestation of bugs, then it is best to place the bag of kisses in the fridge. It will be safer in avoiding the bugs who will chew through the plastic and lay eggs on the chocolates. Put the bag in the back of the fridge, so the temperature around the chocolates doesn’t change suddenly every time the refrigerator door is opened.
