*Alpha acids are determined by conductometric titration (EBC 7.4) in Europe, by spectrophotometry (ASBC Hops-6) in the USA. Oil composition is determined by gas chromatography (ASBC Hops-17, EBC 7.12).

All values represent the medium range of the last 4 years. Be aware that specifically the alpha and oil values can vary in a broad range depending on the relevant crop year.
