Black pepper
Pepper is graded by bulk density, the weight of one litre of peppercorns. Heavier pepper (for example 550 g/l) has more mature berries and fewer light ones, so it is worth more than 500 g/l pepper. FAQ (fair average quality) and ASTA-cleaned pepper are common contract terms.
Vanilla
| Grade | Description | Use |
|---|---|---|
| Gourmet (black) | Long, supple, oily beans with higher moisture | Chefs, bakers, retail |
| Extraction (red) | Drier, often shorter beans | Vanilla extract |
| Cuts | Pieces of beans | Extraction |
Buyers also look at length, the aroma and vanillin content, and splits.
Cloves
Good cloves are whole, dark reddish-brown and have a high oil content, with few headless cloves or stems. Moisture must be low enough for safe storage.
Cleanliness for every spice
Buyers check for extraneous matter, insects, mould and moisture, and often ask for lab results. Add these to your spice lot.
