Understanding the Melting Points of Chocolate: A Chocolatier’s Guide to Storing Fine Chocolates in Warm Weather

As chocolatiers at Rococo Chocolates, we know that the journey of chocolate from our hands to your taste buds involves a fascinating interplay of science and artistry.

One aspect that often puzzles chocolate lovers is the different melting points of various types of chocolate and how this affects storage, especially in warm weather.

We've previously written an article on How To Store Chocolate, but we thought it was worth going into the science of it all.

Let's dive into the delightful science behind this and offer some tips to keep your chocolate in perfect condition, no matter the heat.

The Science of Chocolate Melting

Chocolate is a complex emulsion of cocoa solids, cocoa butter, sugar, and milk solids (in the case of milk chocolate). The key component influencing the melting point is cocoa butter, a fat extracted from cocoa beans.

Cocoa butter consists of several types of fat crystals, known as polymorphs, each with a unique melting point. The main types of polymorphs in cocoa butter are:

1. Form I: Melts at 17°C (63°F)
2. Form II: Melts at 21°C (70°F)
3. Form III: Melts at 26°C (79°F)
4. Form IV: Melts at 28°C (82°F)
5. Form V: Melts at 34°C (93°F)
6. Form VI: Melts at 36°C (97°F)

Melting Points of Different Types of Chocolate

The melting points of chocolate vary depending on the type and composition:

• Dark Chocolate: Contains the highest percentage of cocoa solids and cocoa butter, typically melting between 31°C to 34°C (88°F to 93°F).
• Milk Chocolate: Contains milk solids, which lower the melting point slightly, usually melting between 30°C to 32°C (86°F to 90°F).
• White Chocolate: Lacks cocoa solids and contains milk solids and a higher percentage of sugar, melting at around 28°C to 30°C (82°F to 86°F).

Storing Chocolate in Warm Weather

Now that we understand the melting points, how can we ensure our chocolates remain delectable in warmer climates?

1. Cool and Consistent Temperature: Store chocolate in a cool, dry place away from direct sunlight. The ideal temperature range is between 15°C to 18°C (59°F to 64°F). Avoid refrigeration as it can create moisture, and can cause chocolate to develop a white coating called bloom, which is harmless but affects the appearance and texture.

2. Use Airtight Containers: Humidity is chocolate’s enemy, as it can cause sugar bloom and affect texture. Store chocolate in airtight containers to maintain its quality.

3. Avoid Temperature Fluctuations: Sudden changes in temperature can cause the cocoa butter to separate, leading to bloom. Keep chocolate in a stable environment to preserve its perfect temper.

4. Consider the Type of Chocolate: Since dark chocolate has a higher melting point than milk and white chocolate, it is slightly more resistant to warm temperatures. For extremely warm climates, dark chocolate may be a better choice for maintaining quality during storage and transport.
