Statistical relationships which can be established between a property of barley and another property of its malt‐e.g. the nitrogen‐extract equation‐may help to predict malt quality from barley analyses, but these relationships must be applied only to the variety of barley from which they were originally derived. Such environ mental correlations, which are useful to maltsters, may be unimportant for plantbreeders, who are interested in genetic correlations. It is thus not always appropriate for breeders to rely on tests of barley quality which appeal to maltsters. Just as, in interpreting barley analyses a maltster is using some correlation between barley properties and malt, so in examining malt analyses a brewer is, possibly un‐consciously, correlating the analysis with the finished beer. If, as seems probable, there is some varietal effect in the correlation of malt and beer properties, then trial brewing, in addition to barley and malt analyses, must become an essential part of variety testing.
