Abstract

The effect of the variety on the free amino nitrogen (FAN) content in wort was studied in the set of 24 varieties grown at four different testing sites for a three-year period. FAN was determined by the EBC 4.10 method. The highest average FAN was exhibited by the variety KWS Amadora (193 mg/l). The content of FAN was mostly affected by the year (24%), followed by the site, (15%); the effect of the variety was the lowest (13%). Nearly 50% of the samples exhibited low FAN, slightly over 40% of the samples had medium FAN and 12% of the samples exhibited high FAN.
