Good chocolate requires precision and control. Control over particle size, fat crystallization, viscosity, temperature, structure, etc. You will need to work with the right tools to achieve the right goals.
For a new chocolatier, it can sound a little intimidating, but it shouldn’t be. Once you understand the process, picking the right tools is a fun experience.
Preparing the Raw Material
If you’re doing bean-to-bar, working from cacao beans, the process starts with cleaning and sorting them. This part could be done by hand, just visually sorting out the beans and getting rid of any stones, sticks or impurities.
Some makers sort the beans by size using sieves. This improves roasting consistency because smaller beans heat faster than big ones, so this helps to prevent any over-roasting by keeping the beans uniform-sized. Some makers also use magnets to remove metal contaminants.
Roasting: Developing the Base Flavor
Once cleaned and sorted, the beans are roasted.
Tool:
- Drum roaster (preferred)
- convection oven (small-scale alternative)
What it controls:
- flavor development
- acidity reduction
- shell brittleness (important for the next step)
In this step you get to define the base profile of your chocolate.
Cracking and Winnowing: From Bean to Nib
After roasting, the beans are then broken and separated.
Tools:
- Cracker (this breaks the beans)
- Winnower (this tool separates the shells)
- or a combined cracking and winnowing machine
Process:
- beans are cracked into nibs and shell pieces
- airflow removes the lighter shells
-
heavier nibs are collected
After this is done, you are now ready to work with clean cacao nibs!
Grinding / Pre-Grinding
Before refining, cacao nibs are often ground into a paste.
Tools:
- Pre-grinder / cocoa grinder
- or directly into a melanger (small scale)
This step:
- reduces nib size
- turns solid cacao nibs into cacao liquor (paste)
This isn’t always separate, but it’s common in more efficient setups.
Refining: Building Texture
Now you’re actually building your chocolate. This is where it gets fun.
Tool:
- Melanger (stone grinder)
What goes in:
- cacao liquor (or nibs)
- sugar
- additional cacao butter (depending on your formulation)
What it does:
- reduces particle size
- creates a smooth, homogeneous mass
This is a crucial step for texture. If the particles are too large, you’ll end up with a gritty result. This ensures you end up with a smooth chocolate.
Conching: Flavor and Structure Adjustment
After refining, the chocolate is conched. This means you now work with the mass under heat and movement.
Tool:
- Dedicated conche (industrial)
- or melanger run for extended time (craft setups)
The chocolate is kept in continuous motion for hours. At the same time, heat is applied and the mass is exposed to air.
Over time, here’s what happens:
Volatile acids evaporate. Compounds from fermentation (like acetic acid) are driven off with heat and airflow. This results in a less acidic chocolate.
Fat is redistributed. Cacao butter coats the solid particles more evenly, which improves flow and mouthfeel.
Texture becomes more cohesive and stable.
An industrial conche can take anywhere from 6 to 24 hours. Melanger-based conching often takes 24 to 72+ hours total runtime (refining and conching combined).
Tempering: Controlling Crystallization
After all those hours spinning, the chocolate seems done. But it’s not done until it’s tempered.
Tempering is one of the most important steps in chocolate making because it is what makes it have a nice, glossy finish. It’s what creates that sharp snap when you break a chocolate bar, and that perfect melt-in-the-mouth sensation.
The process involves melting, cooling, and reheating the chocolate to very specific temperatures. This stabilizes the cacao butter crystals into its ideal form (Form V).
Tools:
- Tempering machine
- or manual tempering (marble slab, scraper, thermometer)
Incorrect tempering can result in bloom, a dull finish, and a soft/ bendy texture that doesn’t snap when broken.
Molding and Shaping
Once tempered, the chocolate is ready to be poured into molds!
Tools:
- Polycarbonate molds (this is the industry standard)
- vibrating table (optional, but it helps to remove air bubbles)
What it controls:
- final shape
- surface finish
- consistency
Cooling and Setting
After molding, the chocolate needs to be set under controlled conditions. It should ideally be in a cool, dry area (around 16–20°C). Gradual cooling lets the cacao butter crystals to stabilize and contract properly.
Refrigeration can be used to speed up the setting, especially if you are in a warm climate, but this should be done carefully. Rapid temperature change and high humidity can result in condensation and blooming.
Handling Tools: Used Throughout the Process
Here are some tools you might need that weren’t mentioned above. They don’t belong to a single stage, but are used continuously during production:
- spatulas
- scrapers
- ladles
- dipping forks
Although they don’t change the chemistry of the chocolate, they affect precision and consistency.
Not a One-Size-Fits-All Approach
As you can tell, chocolate can be done in many different ways. You can start with the cacao beans, or with nibs, or even from liquor. Chocolate making is not about having more tools and steps, it’s about knowing how to handle each process carefully to end with the desired result. In a way, chocolate making is a form of art.
