Technical Support | We are pleased to share some averaged data on last year’s composition of aroma substances of some selected hop varieties. This statistic is intended as a helpful indication to achieve consistent hop aroma in beer, especially when changing from one crop year to another.

Company news | After the outbreak of Covid-19 (coronavirus disease 2019), intensive research on potential inhibitors of the viral pathogen SARS-CoV-2 (severe acute respiratory syndrome coronavirus type 2) started worldwide. Since the beginning of last year, hundreds of scientific papers have been published on this topic. Thousands of compounds were screened for their inhibitory effects against coronaviruses.

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.

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.
