The analytical values are typical for each variety at harvest time but values can vary among crop years, growing areas, growers, and with aging after harvest. * Alpha Acids are determined by conductometric titration (EBC 7.4) in Europe. Alpha Acids for extracts are determined by HPLC (EBC 7.7 )in Europe. ** Storage is percent transformation after 6 months at room temperature.  | |
