Hopmarket |The Hopsteiner Guidelines for Hop Buying 2021 have been completed and are now available on our homepage www.hopsteiner.com/de.

Hop market |The crop estimate for the Hallertau was announced on August 25st, meaning that crop 2021 estimates have now been submitted for all German hop growing areas.

Hop Market | The survey of hop acreage in 2021 is completed. Enclosed please find the comparison of acreage from 2018 to 2021 for the world's main producing areas.

Hops have been known for centuries as a cultivated and medicinal plant. The numerous possibilities of applications in the brewing process and also the use of its antibacterial and even anticarcinogenic properties in completely different areas inspire us and are the driving force behind numerous research and development activities in our group of companies.

Technical Support | Oxygenated hop oil compounds, Geraniol and Linalool, when added to the whirlpool and/or during fermentation can take advantage of biotransformation as a result of when yeast converts oxygenated hop oils into floral and citrus tasting compounds (see also January 2019 newsletter).

Technical Support | Hops “keep away certain putrefactions from beverages.” – a statement written by Hildegard von Bingen, in the herbal book “Physica“ from the 12th century [1]. In today’s language, this is equivalent to describing an antimicrobial effect that has been observed for centuries, not only in beer production but also beyond the brewing industry, primarily when gram-positive bacteria must be controlled or inhibited in biochemical processing, as feed additives or food applications.

Technical support | When compared to regular hop addition during wort boiling, late and especially dry hopping make the composition of beer more complex and diverse, which requires additional analytical methods. For this purpose, two new methods are now recommended by the European Brewery Convention (EBC). At the same time, the precision values given for BU (Bitterness Units) measurement have been updated. They now cover also higher ranges as typical to dry-hopped beer.

Technical Support | Downy mildew in hops, usually called peronospora, is caused by Pseudoperonospora humuli and can lead to considerable losses in quality and yield due to weather conditions. For this reason, Dr. Alexander Feiner conducted a study on resistance to downy mildew in hops as part of his doctoral thesis in cooperation with the IPB in Halle (Saale) and the IPK in Gatersleben.
