Barley – Chapter 6 | Official Grain Grading Guide
Net weight of sample
The sample after cleaning and removal of dockage is referred to as the cleaned sample. Its weight is the net weight of the sample. Percentages by weight for grading refer to percentages of the cleaned sample, the net weight.
Hazardous substances in samples
Wear gloves and a mask to handle any samples that you suspect may contain hazardous substances. Hazardous substances are defined in the Regulations as “any pesticide, herbicide, dessicant or inoculant.”
The selection of barley for food purposes is the responsibility of selecting companies. Each individual company has their own selection criteria and specifications. All barley selected for food purposes will be graded according to the specification list in the Barley CW/CE Food primary grade determinant tables.
The selection of barley for malting purposes is the responsibility of selecting companies. Each individual company has their own selection criteria and specifications. All barley selected for malting purposes will be graded according to the specification list in the Barley CW/CE malting primary grade determinant tables.
Once barley has been selected for malting purposes, if there is a disagreement on the assessment of any factors listed in the “Characteristics of Malt Barley” table, the Canadian Grain Commission, upon request will perform an analysis of the disputed factor. A representative portion of not less than 1000 grams of the unload will be forwarded to the Canadian Grain Commission along with a request in writing (form I-106 in western Canada or I-107 for eastern Canada) specifying which factors are to be analyzed.
Characteristics of Malt Barley
- Peeled and Broken
- Other cereal grains
- Wild oats
- Barley of other types
- Total Foreign Material
- Plump and Thin
Specific tolerances are set by the selecting company.
Where grain of any kind is not a registered variety under the Seeds Act, no person shall, except with the permission of the Canadian Grain Commission, assign a statutory grade to that grain which is higher than the lowest grade established by regulation for that kind of grain.
Representative portion for grading
All grading is done on representative portions divided down from the clean sample, using a Boerner-type divider.
The terms “Minimum” and “Maximum” refer to the range of sample portion size to be analyzed when an objective factor is present. The optimum representative portion (see glossary) is determined by taking into consideration the tolerance and concentration of the objective factor being assessed.
