The Scientific-Technical Commission is annually compiling and updating the I.H.G.C. list of international hop varieties produced in each hop-growing nation.
This official variety list of the I.H.G.C. is intended as an aid for the official certification procedure and shall provide an up-to-date overview of the increasingly confusing and highly dynamic field of international hop variety diversity. Usually, it is published every year briefly prior to the BrauBeviale trade fair in Nuremberg in November, which had to be cancelled in 2020 and 2021. The most recent 2021 version of the list was discussed and adopted at the video meeting of the IHB Executive Committee on 15th November 2021. The list has expanded again and now includes 298 different entries of varieties that were commercially grown somewhere on Earth in 2021. All of them also bear a valid name and have a unique three-character code.
The 2021 list was augmented with new I.H.G.C. member Brazil and with Republic of Serbia as a re-entry. It includes the following new names: Adeena (US), Ahhhroma (US), Loerenhop (BE), Lórien (US), Mantiqueira (BR), McKenzie (US), Nectaron (NZ), and YQH1320 (US). Bačka and Robusta (both RS) are again on the list. Minstrel (UK) was deleted as there is no longer any economic production of this variety and AlphAroma (US, BR) is now listed as synonym under the original genotype, Rakau (NZ). Satus is listed under the new name YCR 7, but the previous code SAT remains. Finally, to several US varieties the term ‚Brand‘ has been added as part of the official name.
A special case is “CTZ”, whereby this long-established term has now been added as a separate entry with the same code at the suggestion of the Hop Growers of America. The possibility of officially using the synonym “CTZ” corresponds to the current actual use in the USA, but also in Germany and elsewhere. The three genetically (almost) identical varieties Columbus, Tomahawk and Zeus are synonymous with “CTZ”, but will be kept as individual entries together with their individual codes for the time being.
The version published here represents the final 2021 list as approved by the Executive Committee on 15th November 2021. The next update of the international hop variety list will be published in November 2022.
