Evaluation of bitter acids and polyphenols content in Czech hops harvest in 2013 ? I: Contents of ?- and ?-Bitter Acids

Original language description

The contents of ?- and ?- bitter acids from hops harvested in the Czech Republic in 2013 have been evaluated. The sampling was done in all three growing areas ? Žatec (77.8% of the hop yard areas in the Czech Republic), Úštěk (10.6%) and Tršice (11.7%).The Saaz variety (ŽPČ) was cultivated on 87.8% of the harvest areas, the Sládek variety on 5.6%, Premiant variety on 4.7% and the Agnus variety on 1.0% of the harvest areas. The hops were analyzed in accordance with the Analytica-EBC, method 7.7 (HPLC) and all results are given in weight % in dry matter. The average value for ?-bitter acids in the Saaz variety in the Czech Republic was 3.34% (in the Žatec area 3.46%, in the Úštěk area 3.24% and in the Tršice area 2.90%). The content of ?-bitter acids was 3.58%. The content of ?-bitter acids was 0.78% (18.9% rel.) lower when compared to the year 2012 and 0.32% (8,7% rel.) lower when compared to the average of the last 20 years. The content of ?-bitter acids was 1.17% lower when compared
