Cocoa bean quality: cut test, bean count, Grade I and fine flavour
A cocoa buyer checks a few simple things before paying: how well the beans were fermented, how many are defective, how big they are and how dry they are. This guide explains each test.

The cut test
A sample of beans is cut lengthwise and each bean is checked. Buyers count mouldy beans, slaty beans (grey and unfermented) and insect-damaged beans. Under ISO 2451, good fermented beans have no more than 5% slaty and 5% defective beans by count.
Bean count
The bean count is the number of whole beans in 100 g. Fewer, larger beans usually mean more fat and a better yield. Main crop beans are larger than light (mid) crop beans.
| Check | What buyers look for |
|---|---|
| Fermentation | Brown, well-fermented beans; few slaty beans |
| Defects | Few mouldy, insect-damaged, germinated or flat beans |
| Bean count | Number of beans per 100 g, agreed in the contract |
| Moisture | Dry enough to store and ship safely |
| Foreign matter | Clean beans, no stones or debris |
Fine-flavour cocoa
Some cocoa, often from Latin America, is sold for its flavour, not only its butter. Buyers taste it as liquor or chocolate and pay premiums for well-fermented, clean beans with fruity or floral notes.
