Walnut
The walnut is the kernel of Juglans regia, the Persian or English walnut, a temperate deciduous tree grown across California, China, Chile, Iran, Turkiye, Ukraine, France, Moldova and Central Asia. The nut grows inside a green husk which is removed at harvest, leaving a corrugated shell that splits into two halves around a two lobed kernel. Trade runs in shell and as shelled kernel. Kernel colour is the dominant value driver because walnut oil darkens with heat, light and age, so a pale kernel signals a fresh, well handled crop. Light halves go to premium retail packing, baking and gifting. Darker and broken grades go into bakery, confectionery, cereal, sauces such as pesto and muhammara, and into pressed walnut oil. Walnut is high in polyunsaturated fat, which makes cold storage and nitrogen or vacuum packing normal practice for anything held beyond a few months.

Grades
A walnut kernel is graded on colour against a physical colour standard, on the size and integrity of the piece, and on moisture and defects. Inshell walnut is graded on shell diameter, shell condition and the kernel it yields.
Kernel colour class
4 grades
| Grade | Definition |
|---|---|
| Extra lightPalest class | The palest kernel. Commands the highest premium and is used for retail halves and visible applications. |
| LightLight class | Slightly darker than extra light, still pale. The standard commercial grade for retail and bakery halves. |
| Light amberIntermediate class | Noticeably darker than light, with an amber cast. Used where the kernel is not the visible element. |
| AmberDarkest marketable class | The darkest class admitted to the standard. Used for oil, paste, sauces and industrial baking. |
Kernel style and size
5 grades
| Grade | Definition |
|---|---|
| HalvesAt least one half of a whole kernel | Kernel pieces each comprising at least one half of a whole kernel, with the contract stating the minimum percentage of halves in the lot. |
| QuartersBroken halves | Pieces smaller than a half but larger than the piece grades, being roughly a quarter of a whole kernel. |
| Large piecesRetained on a stated aperture | Pieces retained on the larger sieve aperture named in the contract, with the maximum passing the smaller aperture also stated. |
| Medium piecesRetained on a stated aperture | Pieces sized between two named sieve apertures. |
| Small pieces and mealPassing the smallest stated aperture | Fine pieces and meal used in bakery, coatings and paste. |
Moisture and defects
4 grades
| Grade | Definition |
|---|---|
| Kernel moistureMaximum 5.0 per cent | Walnut kernel is dried to a maximum of 5.0 per cent moisture. Above this the kernel goes rancid and moulds in store. |
| Inshell moisture, dryMaximum 12.0 per cent | Inshell walnut sold as dry must not exceed 12.0 per cent moisture across nut and kernel. |
| Inshell moisture, freshMinimum 20.0 per cent | Fresh or wet walnut is a separate product with a minimum moisture of 20.0 per cent and a short shelf life. |
| Quality classExtra Class, Class I, Class II | Three classes with progressively wider tolerances for shrivelled, mouldy, rancid, insect damaged and otherwise defective kernel. Living pests are not permitted in any class. |
Inshell size
3 grades
| Grade | Definition |
|---|---|
| Screened diameter bandMinimum diameter in millimetres | Inshell walnut is screened over round hole sieves and the contract names the band, for example 30 mm to 32 mm. A minimum diameter alone may be stated where a lot is sold as a single cut. |
| Shell conditionLight, well sealed, clean | Shell colour, whether the suture is sealed and whether the shell is free of husk stain are stated separately from diameter. |
| Kernel yieldPercentage by weight | The weight of kernel recovered from a cracked sample as a percentage of the inshell weight, used to price an inshell lot against kernel value. |

Timing
Harvest is when the crop is taken at origin. Arrival is when a shipment from that origin typically lands in a consuming market. The gap between them is processing, grading and the voyage.
