R-200.09.020 [2016-03] Thousand Kernel Weight of Malt

Application/Purpose

This method describes how to determine the thousand kernel weight of malt.

Scope of Application

Barley malt intended for use in beer brewing or elsewhere in the food industry.

Principle

The thousand kernel weight is more meaningful for evaluating malt quality than the hectoliter weight. A relationship exists between the thousand kernel weight and both the sieving test and the extract yield of malt, since the percentage of extract contained in malt increases with increasing thousand kernel weight, given that the protein content remains constant. The thousand kernel weight rises with increasing moisture content of the malt; therefore, it must be calculated in reference to the dry substance of the malt to produce an objective measurement [1].
