Two versions of Seck mill and one rotating Disc mill have been evaluated to assess their suitability for malt analysis and particularly for measurement of the Hot Water Extract as described in the Recommended Methods of Analysis of the Institute of Brewing. Measurements of Hot Water Extract and sieve analyses were carried out on a range of malts of different modifications and moisture contents to determine the reproducibility and grinding characteristics of each mill. The mills proved equally reliable for the measurement of Hot Water Extract despite differences in roll speed and despite differences in the sieve analyses. Furthermore, the mills in new condition gave values somewhat higher than those obtained with the mills currently used in commercial laboratories. The rotating Disc mill gave reproducible values for differences in extract using the Institute mashing procedure on coarse and fine grists. It also proved easier to operate than the Seck mills.
