How Long Can chocolate sit out?

Chocolate is a delicious treat that many people enjoy. However, chocolate can go bad if left out at room temperature for too long. So how long can chocolate really sit out before it spoils? Here is a comprehensive guide to how long different types of chocolate last and how to store chocolate properly.

Quick Answers

Here are quick answers to common questions about how long chocolate can sit out:

  • Dark chocolate can sit out for 1-2 weeks if properly stored.
  • Milk chocolate and white chocolate will last only about 1 week at room temperature.
  • Filled chocolates and chocolate with nuts or fruit will last about 1 week unrefrigerated.
  • Melted chocolate that has resolidified can last 2-4 months at room temperature.
  • Chocolate is best stored in a cool, dry place between 60-70°F.
  • Refrigerating or freezing chocolate can cause condensation and texture changes.
  • Look for signs of spoilage like white spots, dull color, soft texture, or lost aroma.
  • Chocolate may develop a grey sheen called fat bloom when stored improperly.

How Long Does Dark Chocolate Last at Room Temperature?

Dark chocolate has a longer shelf life than milk or white chocolate. The high cocoa content and low dairy act as natural preservatives. Properly stored dark chocolate can last:

  • 1 month past the “best by” date.
  • 3-6 months in a sealed package.
  • 1-2 weeks when opened.

The shelf life depends somewhat on the specific cocoa percentage. Dark chocolates with 70% cocoa or more tend to last a bit longer than chocolates in the 50-60% range. Storing dark chocolate properly is key for maximizing shelf life.

How to Store Dark Chocolate

Here are some tips for storing dark chocolate:

  • Store in a cool, dark place between 60-70°F.
  • Keep chocolate away from direct sunlight, which can cause melting.
  • Use an airtight container or wrap tightly in plastic wrap.
  • Don’t refrigerate, as condensation can form.
  • If chocolate has a creamy filling, refrigeration may be needed.
  • Freeze for long term storage up to one year.

How Long Does Milk Chocolate Last?

Because of its milk content, milk chocolate has a shorter shelf life than dark chocolate. Properly stored, milk chocolate will last:

  • 2-4 weeks past the printed date.
  • 3-4 months in a sealed package.
  • About 1 week when opened.

The higher fat and dairy content make milk chocolate prone to spoilage by heat, humidity, and air. Take steps to store milk chocolate properly.

Storing Milk Chocolate

Follow these tips for storing milk chocolate:

  • Refrigerate opened packages for up to three weeks.
  • Freeze unopened milk chocolate for up to 8-10 months.
  • Use an airtight container at room temperature.
  • Keep away from heat sources like the oven.
  • Avoid temperature fluctuations.

How Long Does White Chocolate Last?

Since it contains no cocoa solids, white chocolate has the shortest shelf life. Properly stored, white chocolate will last:

  • 2-3 weeks past the printed date.
  • 3-4 months in a sealed package.
  • About 1 week when opened.

White chocolate is highly prone to spoilage so proper storage is important. Take care not to let white chocolate get too warm or be exposed to excess moisture.

Storing White Chocolate

Here are some tips for maximizing white chocolate’s shelf life:

  • Refrigerate opened packages.
  • Double wrap in plastic wrap or foil.
  • Freeze for 4-6 months to extend shelf life.
  • Put in an airtight container.
  • Keep away from heat and humidity.

How Long Do Chocolate Bars Last?

The shelf life of chocolate bars depends on the type. Here’s how long different chocolate bars last:

Chocolate Bar Type Unopened Shelf Life Opened Shelf Life
Dark chocolate 1 year 3-4 months
Milk chocolate 8-10 months 3-4 weeks
White chocolate 6-8 months 3-4 weeks

Proper storage like keeping bars cool and dry in airtight containers helps maximize freshness.

How Long Do Filled Chocolates Last?

The shelf life of filled chocolates depends on the filling:

  • Chocolate with creams or ganache: 1-2 weeks unrefrigerated, 2-3 months refrigerated
  • Chocolate with caramel or fudge: 2-3 weeks unrefrigerated, 3-4 months refrigerated
  • Chocolate with nuts: 2-3 weeks unrefrigerated, 4-6 months refrigerated
  • Chocolate with fruit: 1 week unrefrigerated, 2-3 months refrigerated

The dairy and high moisture content in fillings make filled chocolates highly perishable. Keeping them cool helps prevent spoilage.

Storing Filled Chocolates

Use these storage methods to keep filled chocolates fresh longer:

  • Refrigerate opened packages.
  • Seal boxes tightly between uses.
  • Freeze for long-term storage.
  • Avoid temperature changes.
  • Keep away from direct sunlight.

How Long Does Melted Chocolate Last?

Melted chocolate that has resolidified and is stored properly can last:

  • Dark chocolate: 2-4 months at room temperature.
  • Milk chocolate: 1-2 months unrefrigerated.
  • White chocolate: 2-3 weeks unrefrigerated.

Melted chocolate is still prone to spoilage from heat, humidity, condensation, and air exposure. Follow proper storage methods.

Storing Melted Chocolate

Here are some tips for storing melted chocolate:

  • Let it fully harden before sealing in an airtight container.
  • If condensation forms, gently wipe off.
  • Refrigerate milk or white chocolate.
  • Freeze for longer shelf life.
  • Keep away from heat sources and sunlight.

How to Tell if Chocolate Has Gone Bad

Watch for these signs that indicate spoiled chocolate:

  • White spots or streaks – Caused by fat and sugar separating due to heat.
  • Dull, grey color – Indicates dried out, old chocolate.
  • Soft texture – Chocolate should snap cleanly, not bend or mush.
  • Lost aroma – Chocolate should smell rich and robust.
  • Mold – Visible fuzzy mold is a sign of spoilage.

Chocolate that is past its prime may have diminished flavor and texture but is generally still safe to eat.

What Is Chocolate Bloom?

When chocolate turns gray or gets a dusty coating, it has developed bloom. Bloom is caused by:

  • Improper temperature changes – Rapid warming and cooling causes fat crystals to rise to the surface.
  • Humidity – Moisture interacts with sugar crystals to create bloom.
  • Poor storage – Direct sunlight, lack of packaging, temperature swings.

While visually unappealing, chocolate bloom does not make chocolate unsafe. It can be reversed by melting and resolidifying the chocolate.

How to Store Chocolate Properly

Follow these tips for maximizing chocolate’s shelf life:

  • Store at cool room temperature between 60-70°F.
  • Keep chocolate away from direct sunlight, heat sources, and humidity.
  • Use an airtight container or wrap tightly.
  • Refrigerate milk, white, and filled chocolates.
  • Freeze for long-term storage.
  • Keep chocolate dry – wipe containers before sealing.
  • Avoid temperature fluctuations.

With proper storage and handling, chocolate can maintain optimal freshness and flavor beyond its expiry date.

Frequently Asked Questions

Does chocolate go bad?

Yes, chocolate can go bad over time. Dark chocolate lasts the longest – about 1 year unopened or 3-4 months opened. Milk and white chocolate last about 6-8 months unopened or 3-4 weeks opened. Signs of spoiled chocolate include dull color, soft texture, white spots, and loss of aroma.

Can you eat expired chocolate?

Most chocolate is still safe to eat a few months past its printed expiration date, though the flavor and texture quality will diminish over time. Discard chocolate that shows clear signs of spoilage like mold, rancid smell, or very dull color.

How do you get bloom off chocolate?

Chocolate bloom can be reversed by melting the chocolate down completely then allowing it to fully resolidify in proper storage conditions. Gentle wiping with a dry towel can also help remove some surface bloom. Prevent future bloom by keeping chocolate tightly sealed and away from temperature fluctuations.

Does refrigerating chocolate ruin it?

Refrigerating chocolate, especially milk or white varieties, helps extend its shelf life. However, cold temperatures can cause sugar bloom on the surface. Let refrigerated chocolate come completely to room temperature before unwrapping to prevent condensation which leads to bloom.

Can you freeze chocolate bars?

Yes, freezing is an excellent long-term storage method for chocolate bars. Freeze the bars in their original packaging for 8-12 months. Allow frozen chocolate to fully thaw in the fridge before using to prevent condensation from humidity.

How long does homemade chocolate last?

Homemade chocolate lasts 1-2 months stored in an airtight container at cool room temperature. Since there are no preservatives, homemade chocolate has a shorter shelf life than store-bought. Store in the fridge or freezer for maximum freshness.


Knowing how to properly store chocolate is key to maximizing its shelf life. Dark chocolate lasts the longest at room temperature, while milk, white, and filled chocolates require refrigeration. Look for signs of spoilage like dulling, soft texture, and white bloom. With the right storage methods, chocolate can retain optimal flavor and texture well beyond its printed expiration date.
