Grading and selecting Cocoa

For chocolate makers, confectioners, and bulk buyers, identifying high-quality cocoa is critical. This guide explains how to assess Ugandan cocoa beans using industry-standard grading methods, ensuring you source only the finest beans for your products.
🔬 Step 1: The Cut Test – Measuring Fermentation & Defects
✅ How to Perform a Cut Test
- Take a 300g random sample from the batch.
- Cut 100 beans lengthwise with a sharp knife.
- Examine the internal color & defects.
📊 Grading Standards
Grade | Fermentation Level | Acceptable Defects | Use Case |
Premium (Fine) | ≥90% purple/brown | ≤3% defects | Craft chocolate, luxury confectionery |
Standard | 70-89% purple/brown | ≤5% defects | Bulk chocolate, cocoa powder |
Reject | <70% purple (slaty) | >5% defects | Industrial use only |
❌ Common Defects to Reject
- Mold (white/green spots inside beans)
- Insect damage (holes, tunnels)
- Germinated beans (sprouts inside)
- Flat/underdeveloped beans
👃 Step 2: Aroma & Flavor Assessment
✅ Roast & Smell Test (Critical for Buyers!)
- Roast a small batch at 120°C for 15 mins.
- Crush beans and inhale deeply:
✔ High-Quality Cocoa Aroma:
- Fruity (berries, citrus)
- Floral (jasmine, honey)
- Nutty/chocolatey (hazelnut, caramel)
❌ Poor-Quality Signs:
- Vinegary/sour (over-fermented)
- Smoky/burnt (improper drying)
- Earthy/musty (mold contamination)
🍫 Taste Test (Liquor Evaluation)
- Grind roasted beans into cocoa liquor.
- Good cocoa: Smooth, balanced bitterness, fruity aftertaste.
- Bad cocoa: Harsh, astringent, or bland.
📈 Case Study: Bundibugyo Farmers Achieve 85% Fermentation Rates
The Challenge
Smallholder farmers in Bundibugyo struggled with:
- Low fermentation rates (50-60%) → bitter beans
- Mold contamination → rejected exports
The Solution
Zola Produce trained farmers on:
✔ Proper wooden box fermentation (6 days, turning every 48hrs)
✔ Raised bamboo drying racks (no ground contact)
✔ Strict moisture control (≤7.5%)
The Results
✅ 85% well-fermented beans (up from 50%)
✅ Zero mold complaints from European buyers
✅ 20% higher prices for farmers
