Malting extremely small quantities of barley
Micromalting procedures for malt quality analysis typically use 150–500 g of barley and can produce malt with characteristics representative of malts produced on a commercial scale. Modifications to routine micromalting protocols, in which small quantities of grain contained within inexpensive mesh containers are surrounded by a larger quantity of grain in standard malting containers, allow representative malts to be generated from 2 g of barley. This reduced scale enables multiplexing of samples within a malting container, thereby increasing the potential malting throughput of existing micromalting equipment. The combination of this extremely small-scale malting procedure with previously described reduced-quantity mashing and malt analysis procedures effectively expands the capacity for preliminary screening of malt quality characteristics, benefiting malting barley germplasm development programs by both increasing malting quality analysis sample throughput and reducing analysis turn-around time. In addition, the ability to generate and analyze representative malts on this very small scale would be useful in research studies where grain quantities are limited, such as might occur in specially developed genetic populations for basic research studies on the genetic and biochemical underpinnings of malting quality.
