Why Texture Matters: Achieving Chocolate Perfection with KADZAMA Melangers

For professional chocolatiers and bean-to-bar makers, texture is as important as flavor. That smooth, melt-in-your-mouth experience is what defines premium chocolate. But achieving it takes more than quality ingredients—you need precise control over texture, and that starts with the right melanger.

The Role of Texture in Premium Chocolate

Texture shapes how we perceive chocolate. Smoothness enhances flavor delivery and overall enjoyment. Grittiness, even if flavors are great, can ruin the experience. The sweet spot? Chocolate with particle sizes refined to around 20 microns—just below the tongue's sensory threshold.

Why it matters:

• Silky Mouthfeel: Particles under 20 microns feel smooth and luxurious.
• Even Flavor: Uniform texture means balanced flavor distribution.
• Professional Finish: Fine texture contributes to glossy appearance.

Achieving such fineness and consistency in texture comes down to production techniques. The key factors are particle size and the even distribution of ingredients (cocoa solids, sugar, cocoa butter, etc.) in the finished chocolate.

Grinding to 20 Microns: The Gold Standard

How fine is fine enough? In practice, top chocolatiers aim to refine their chocolate to about 20 microns (0.020 millimeters). For context, 20µm is about half the width of a human hair – truly microscopic. This target is chosen because it is well below the threshold of what the tongue can feel​.

By reducing cocoa and sugar particles to ~20 microns or smaller, you ensure the chocolate will feel impeccably smooth (often described as silky or velvety) with no detectable grain.

Achieving this level of fineness is a meticulous process. In bean-to-bar production, it’s typically done with a stone grinder known as a melanger. The melanger’s rotating granite wheels crush and grind the ingredients against a stone base.

Why 20 microns?

At ~20µm, particles are small enough that your tongue perceives the chocolate as perfectly smooth, but the chocolate still has enough structure to avoid problems that can occur with over-refining. Too fine – say under 10µm – and the chocolate can become pasty or too thick.

Thus ~20µm is a sweet spot: below sensory detection for grittiness, yet maintaining good flow and snap in the finished product.

However, particle size isn’t the whole story. Equally important is what happens during the latter stages of that 24–48 hour refining period – the conching process.

The Importance of Conching

After fine grinding, the next crucial step is conching—a prolonged mixing, aerating, and heating process. In a melanger, conching happens naturally as the machine continues to churn the chocolate. This stage is vital for flavor development and texture consistency.

Key effects of conching:

• Volatile removal – Harsh acids and bitterness evaporate, mellowing the flavor.
• Emulsification – Cocoa butter coats all particles, creating a smooth, uniform texture.
• Particle rounding – Friction smoothes sharp edges, enhancing mouthfeel.
• Viscosity control – The chocolate becomes fluid and workable for tempering.

In short, conching unites texture and flavor. A well-conched chocolate will have no off-flavors and a delightful aroma, with a consistent, flowing texture.

For many bean-to-bar makers and boutique producers, the melanger combines both grinding and conching in one machine. That makes its performance even more critical.

Not all melangers are equal in this task. The design and features of the melanger determine the quality of texture and flavor you achieve.

What Sets KADZAMA Melangers Apart

A melanger is the workhorse of bean-to-bar chocolate making. High-quality melangers distinguish themselves through thoughtful engineering that addresses common challenges. KADZAMA’s melangers offer:

• Spiral Groove Stones: Better contact and circulation for faster, more even grinding.
• Reverse Function: Clears clogs and ensures continuous, even refining.
• Robust Engine: Built for 24/7 operation without compromising performance.
• Hygienic Design: No lubrication points near food zones; easy to clean and maintain.

Together, these features allow consistent refinement to 20 microns and effective conching in a single machine.

Conclusion: Texture Is Craftsmanship

In fine chocolate, texture is the touchstone of quality. Achieving a sublime, smooth texture requires both scientific understanding and reliable tools.

With KADZAMA’s melangers, you gain the tools to do both—reliably and efficiently.
