Malting and Raw Materials

Malt Evaluation - Maltster's View

Is it Malt yet?


Evaluation, Malt, Specifications, Maltster


One can argue that malt analyses and the ensuing certificate of analysis or COA were first developed for the maltster to answer the key question: "Is it Malt yet?" regarding the completion of the malting process and the achievement of quality malt.
In this lecture, we will build out our thoughts on how the barley kernel is reacting to the malting process and the outcomes that are measured by the maltster, and what they mean to the maltster.
