This report describes a further International Hop Variety Trial and outlines the object, history and organization of the trials. Four varieties (Hallertau, Saaz, Fuggle and Northern Brewer) were tested in seven countries (Czechoslovakia, Germany (West), Denmark, Spain, France, England and Yugoslavia). The trial provided further evidence of the influence on α‐acid content of mean air temperature during the development and ripening of the hop cone, and of the existence of a critical optimum temperature during this period. Over‐riding any effect of season, however, was the influence of variety on α‐acid production, and Northern Brewer again proved outstanding in this respect in all countries.
