Bean-to-bar chocolate making starts with whole raw cacao beans and ends with a finished bar. The six main steps are roasting, cracking, winnowing, refining (in a melanger), tempering, and molding. The entire process takes approximately 36 to 54 hours of clock time, though most of that is unattended. Active hands-on time for a 1 to 2 lb batch is approximately 3 to 4 hours.
What You Are Actually Making
When you make bean-to-bar chocolate, you are producing chocolate from the raw material rather than from pre-made chocolate liquor or cocoa powder. This distinction matters because every flavor decision from fermentation through roasting through conching determines what ends up in your bar.
The simplest finished chocolate is two ingredients: cocoa nibs and sugar. Dandelion Chocolate’s standard is 70% cocoa and 30% sugar, made with no added cocoa butter, lecithin, or vanilla. This two-ingredient approach is the American craft chocolate statement — it privileges origin flavor transparency over the smooth, fat-rich texture of European-style bars. You can taste this difference clearly.
Before You Start: Getting Beans
Your starting material defines your ceiling. The best process in the world cannot make excellent chocolate from poorly fermented beans. Buy beans from suppliers who provide information about origin, fermentation method, and flavor notes. Dandelion, Chocolate Alchemy, Meridian Cacao, and similar suppliers work with known farms or cooperatives.
Evaluate bean quality with a cut test: cut 10 to 20 beans longitudinally. At least 75% should show brown cross-sections (well-fermented). Purple or slate-colored interiors indicate under-fermentation. Shriveled, moldy, or hatched-out beans are defects. Assess before you invest 30 hours in refining.
Step 1: Roasting
Equipment: Behmor 2000AB or home oven at 325°F Time: 20 to 35 minutes active; 6 hours rest after
Load 1 to 1.5 lbs of beans in the Behmor on P1. Roasting proceeds through three phases. Phase 1 (drying) takes 8 to 20 minutes — moisture is removed, no flavor chemistry yet. Phase 2 (development) takes 2.5 to 5 minutes — flavor precursors build. Phase 3 (finishing) takes 3 to 6 minutes — end-of-roast target is 254 to 262°F bean temperature.
The most important cue is aroma: stop when you smell a harsh or acrid note from the vents. When in doubt, stop earlier rather than later. Under-roasted beans will taste flat but over-roasted is harder to fix in the melanger.
After roasting, spread beans on a clean surface and let them cool completely. Rest at least 6 hours before cracking — fresh-roasted beans are brittle in a way that prevents clean cracking.
Oven alternative: 325°F preheated, 1 kg beans on sheet trays, approximately 30 minutes, stirring every 10 minutes. Less consistent but workable.
Step 2: Cracking
Equipment: Champion juicer with blank screen, or zip-lock bag and rolling pin for small test batches Time: 10 to 20 minutes per pound
Run roasted beans through the Champion with the blank screen. The output is cracked pieces of various sizes plus loose husk. At approximately 1 lb per minute, a 1.5-lb batch takes about 2 minutes.
You want each bean broken into 3 to 6 roughly equal pieces. Very coarse cracking (large chunks with husk still bonded) means the Champion is running too fast or beans need more pressure. Very fine cracking with lots of powder means the gap is too small.
Step 3: Winnowing
Equipment: Standing fan or hair dryer; two large bowls Time: 10 to 30 minutes per pound depending on method
Winnowing separates husk from nibs. Husk is lighter; nibs are heavier. An air stream at the right velocity carries husk aside while nibs fall.
Fan method: Set a standing fan to medium. Pour cracked material slowly from one bowl, positioned high, to another bowl below, passing through the fan’s horizontal air stream. Husk blows aside; nibs fall into the lower bowl.
Hairdryer method: Point the hairdryer horizontally across the falling stream. Works but is less consistent than a fan. Apply Dandelion’s Ten-Minute Rule: no more than 10 minutes per batch.
The target is under 2% husk by weight. The FDA limit for commercial products is 1.75%. For your first batches, do two passes to push husk below this threshold.
Step 4: Refining in the Melanger
Equipment: Premier Chocolate Refiner ($250) or Spectra 11 ($479)
Time: 18 to 30 hours
This step is where chocolate is made. The melanger’s granite rollers crush and shear nibs and sugar until particles reach the 10 to 20 micron range. Simultaneously, the mechanical energy and air exposure conch the chocolate — driving off volatile acids and distributing fat through the mass.
Formula for two-ingredient 70% chocolate: Sugar weight = (Nib weight / 0.70) - Nib weight Example: 650g nibs → (650 / 0.70) - 650 = 279g sugar
Load nibs into the melanger first. Run for 30 minutes until a rough paste forms. Add sugar gradually. Over the next 18 to 30 hours, the mass transitions from chunky paste to smooth chocolate.
At 8 hours, take a taste. The chocolate has interesting flavor but may still be slightly gritty. At 18 to 24 hours, the texture should be smooth and the flavor more developed. At 30 hours, the flavor is at an optimal point before diminishing returns.
Do not add water. Ever.
Optional: Run nibs through the Champion for a second pass (pre-refining) before loading the melanger. This reduces melanger time by several hours.
Step 5: Tempering
Equipment: Probe thermometer; bowl; solid tempered chocolate for seed Time: 20 to 40 minutes
Remove chocolate from the melanger when it is still warm (above 40°C). For the seed method: warm the chocolate to 120°F (48.9°C). Add solid tempered chocolate at about 25% of the total weight. Stir continuously until solid melts completely and the combined mass reaches 86 to 87°F.
Working range for dark chocolate: 85.5 to 87°F (29.7 to 30.6°C). Do not exceed 90°F. If the chocolate cools below 84°F during work, it thickens and may have crystallization issues. Warm gently over barely warm water.
Test: dip the tip of a spoon, wait 3 minutes at room temperature. Firm, with even sheen and no streaks = good temper.
Step 6: Molding
Equipment: Polycarbonate bar molds Time: 15 to 20 minutes setting time
Pour tempered chocolate into clean, dry polycarbonate molds. Tap the mold on a flat surface 2 to 3 times to release any air bubbles. Set aside at room temperature (ideally 65 to 72°F) for 15 to 20 minutes.
Well-tempered chocolate will contract slightly from the mold edges as it sets. When you can see a slight gap at the edges and the surface looks matte, the bars are ready to demold. Invert the mold and the bars should fall out cleanly.
What Your First Batch Will Taste Like
Your first batch will almost certainly be imperfect. Common issues:
Slightly gritty: Not enough melanger time. Run 24 to 30 hours next time. Flat flavor: Beans may have been under-fermented, or the roast was too light. Vinegary/acidic: Roast may not have gone to 260°F (acetic acid boils at 244.6°F), or insufficient conching. Soft, no snap: Tempering needs work — likely temperature exceeded 90°F or working temperature was too low. White bloomy surface: Tempering was inadequate. The chocolate is still edible but Form V crystallization did not complete properly.
Every batch teaches you something. The feedback loop from raw beans to tasting is why bean-to-bar making is so engaging.

Frequently Asked Questions
- How long does it take to make bean-to-bar chocolate?
- Total clock time from raw beans to finished bars is approximately 36–54 hours, but most of that is unattended. The breakdown: 20–35 minutes roasting, 6 hours resting, 1 hour cracking and winnowing, 18–30 hours in the melanger (run overnight), 20–40 minutes tempering, 15–20 minutes setting. Active hands-on time is approximately 3–4 hours per batch.
- What is a two-ingredient chocolate and why make it?
- Two-ingredient chocolate uses only cocoa nibs and sugar — no added cocoa butter, lecithin, or vanilla. Dandelion Chocolate's standard is 70% cocoa and 30% sugar. The two-ingredient format prioritizes origin flavor transparency: there are no additives masking or modifying the bean's natural character. It produces a drier, crisper mouthfeel compared to European-style bars with added fat.
- How do I know if my cacao beans are good quality?
- The cut test is the standard quality indicator. Cut 10–20 beans longitudinally and examine the cross-sections. At least 75% should be brown (well-fermented). Purple or slate-colored interiors indicate under-fermentation. Shriveled, hatched, or moldy beans are defects. Well-fermented beans also smell complex and pleasant when cut, not flat or harsh.
- What is the formula for two-ingredient 70% chocolate?
- Sugar weight = (Nib weight / 0.70) - Nib weight. Example: 650g of nibs requires (650 / 0.70) - 650 = 279g of sugar to make a 70% chocolate. This formula scales linearly — adjust the percentage denominator (0.70) to make different percentages.
- Why should I never add water to a melanger?
- Water causes irreversible seizing of the chocolate mass. Even a small amount of water dissolves sugar surfaces, causing particles to clump and viscosity to spike dramatically. The resulting mass cannot be saved. This is absolute: the melanger must be completely dry before loading, and nothing wet — tools, hands, ingredients — should contact the chocolate during refining.
- What is the most common beginner mistake in bean-to-bar making?
- Stopping the melanger too early is the most common mistake. Gritty chocolate that did not refine to the 10–20 micron range is the most frequent quality problem beginners encounter. The fix is straightforward: run 18–30 hours and verify particle size with a grindometer rather than guessing from time alone.
