What Is Ganache?
Ganache is a smooth emulsion made by combining chocolate and heavy cream. It can be adjusted to different textures depending on the ratio and is commonly used in:
-
Cakes and cupcakes

Chocolate fillings
-
Drip cakes
-
Dessert sauces
Because ganache contains dairy, it is a perishable food, which directly affects its shelf life.

-
Should be covered and kept away from heat and sunlight
Ganache made with dark chocolate lasts slightly longer than milk or white chocolate due to lower dairy and sugar content.
If your kitchen is warm or humid, ganache should be refrigerated immediately.
How Long Does Ganache Last in the Fridge?
Refrigeration significantly extends the shelf life of ganache.
Refrigerated Ganache Shelf Life
-
Dark chocolate ganache: 7–14 days
-
Milk chocolate ganache: 5–7 days
-
White chocolate ganache: 4–6 days
Best Practices for Storing Ganache in the Fridge

Cool ganache completely before freezing
-
Portion into airtight containers or freezer bags
-
Label with date and chocolate type
How to Thaw Frozen Ganache

Thaw overnight in the refrigerator
-
Reheat slowly using a double boiler or microwave at low power
Factors That Affect Ganache Shelf Life
Several variables determine how long ganache lasts:
1. Chocolate-to-Cream Ratio
-
Higher chocolate ratios = longer shelf life
-
Truffle-style ganache lasts longer than pourable ganache
2. Type of Chocolate
-
Dark chocolate lasts longest
-
White chocolate spoils fastest
3. Storage Temperature
-
Warm temperatures speed up spoilage
-
Consistent refrigeration extends freshness
4. Added Ingredients
-
Butter, fruit purées, or alcohol can change shelf life
-
Alcohol slightly extends longevity
How to Tell If Ganache Has Gone Bad
Always check ganache before use. Discard it if you notice:
-
Sour or off smell
-
Mold growth
-
Slimy or grainy texture
-
Visible separation that won’t recombine
-
Unusual taste
When in doubt, throw it out especially with dairy-based desserts.
Does Ganache Need to Be Refrigerated?
Yes, ganache should be refrigerated if not used within 24 hours.
You can leave ganache out briefly for decorating or serving, but for storage, refrigeration is the safest option.
Can You Leave Ganache Out Overnight?
Ganache can be left out overnight only if:
-
The room is cool
-
It’s made with dark chocolate

It’s tightly covered
Otherwise, refrigeration is recommended to avoid bacterial growth.
Can You Reheat Ganache After Refrigeration or Freezing?
Yes. To restore texture:
-
Use a double boiler, stirring gently
-
Microwave in short intervals (10–15 seconds)
-
Avoid overheating, which can cause separation
Tips to Extend Ganache Shelf Life
-
Use fresh heavy cream
-
Avoid introducing moisture
-
Store in airtight containers
