This Method was last updated in January 2019. The updates cover the “Procedure” and “Precision” chapters. In the “Procedure” chapter, the extraction parameters are more specified and the method of conductometric titration has been harmonized with Method 7.5 “Bitter Substances in Hops and Hop Products: Lead Conductance Value and Total Resin, Soft Resin and Hard Resin”. The “Precision” chapter now reflects the recent results of a collaborative trial on both hops and pellets carried out in 2018 covering a broader range from low to high alpha varieties as typically used today.
