How Long Does Ganache Last? Does it Go Bad?

Ganache is a luxurious, creamy mixture of chocolate and heavy cream that can be utilized in various desserts and pastries.

Whether you’re making truffles, frosting on cakes, or adding a layer of richness to a chocolate cream pie, ganache is a versatile ingredient that many bakers depend on.

But how long can you keep ganache around? Does it go bad, and if so, what signs should you look for?

In this article, we’ll take a closer look at ganache, discussing how to store it properly, signs of spoilage to look out for, and how long it can last before it goes bad.

What is Ganache?

Ganache is a mixture of chocolate and heavy cream that is heated together until the chocolate has melted.

The result is a smooth, velvety spread that can range in texture from thin and pourable to thick and firm depending on the ratio of chocolate to cream used.

In general, the more chocolate added to the mixture, the firmer the ganache will become.

Ganache can be used as a glaze, filling, frosting, or topping for a variety of desserts, including cakes, cookies, and truffles.

It is also a popular ingredient in many candy recipes, including chocolate-covered cherries and caramels.

Ganache is rich and decadent, making it a favorite among bakers and chocolate lovers alike.

How Long Does Ganache Last?

The shelf life of ganache depends on several factors, including its storage conditions, the ingredients used, and the presence of any additives such as alcohol or flavorings.

Unopened Ganache

If you buy ganache from the store or make it at home and keep it in an unopened container, it can last up to two weeks in the refrigerator.

Make sure to store it in an airtight container to prevent it from drying out or absorbing any other flavors from the fridge.

If you need to store it for longer, you can freeze it for up to three months.

However, keep in mind that the texture may change slightly after freezing, becoming slightly grainy or less smooth.

Opened Ganache

Once you open the container, the shelf life of the ganache will be shorter.

The general rule of thumb for opened ganache is that it should be consumed within five days of being made, assuming it is stored properly.

This means keeping it in an airtight container in the refrigerator and making sure that it is not exposed to light or humidity.

Ganache can spoil quickly if not stored correctly, so it’s essential to keep it in the fridge and keep an eye on it for any signs of spoilage.

How to Tell if Ganache Has Gone Bad?

It’s usually pretty easy to tell if ganache has gone bad just by looking at it or smelling it.


If the ganache appears grainy, lumpy or gritty, it has likely gone bad.

You may also notice a white film on the surface of the ganache, which can be a sign of separation or spoilage.

If you observe any of these signs, it’s best to discard the ganache.


If the ganache has an off smell or a strange odor, it’s another sign that it may have gone bad.

Ganache should smell like chocolate and cream, and any unusual or acidic odors should be taken as a warning sign.


If the ganache tastes sour, acidic, or otherwise unpleasant, it’s a clear sign that it has gone bad.

Spoiled ganache may also have a chalky or powdery mouthfeel, indicating a breakdown of the structure.

How to Store Ganache?

Proper storage of ganache is essential for ensuring its quality and longevity.

Store in the Refrigerator

Ganache should always be stored in the refrigerator, as it is heat sensitive and can spoil quickly if left at room temperature.

Kept in the fridge, ganache can last for up to five days after being opened.

If you don’t plan to use the ganache all at once, you can divide it into smaller portions and keep them in airtight containers in the fridge.

Freeze Unused Portions

If you have unused portions of ganache that you want to save for later use, it’s best to freeze them.

Freezing can extend the shelf life of ganache for up to three months.

Just make sure to store it in an airtight container or freezer bag to prevent freezer burn.

Avoid Excessive Heat or Light Exposure

Ganache should be kept away from excessive heat or light, which can cause the chocolate to melt or the cream to separate.

It’s best to store it in a cool, dark place in the fridge, away from any heat sources.

Add a Little Alcohol

Adding a small amount of alcohol, such as rum or brandy, can help to extend the shelf life of ganache.

The alcohol acts as a preservative, helping to prevent the growth of bacteria and yeast that can lead to spoilage.

However, be sure not to add too much alcohol, as this can alter the texture and flavor of the ganache.


Ganache is a delicious and versatile ingredient that is used in a wide range of desserts and pastries.

To ensure its longevity, proper storage is crucial, and it should always be kept in the fridge.

Ganache can last up to five days after being opened if stored correctly, and up to two weeks unopened, refrigerated in an airtight container.

Once you notice signs of spoilage such as a strange odor, sour taste, or appearance changes, it’s time to discard the ganache.
