Heat recovery | Stopping the use of fossil fuels is more urgent than ever, but still no emission-free maltings has been constructed so far. On average, malting of barley results in a carbon footprint in the range of 100–350 kg per ton of produced malt, depending on the malt variety, the efficiencies and used fuel types. In the following article the authors from Holland Malt, The Netherlands, introduce the concept of a completely electrified kilning system powered by large-scale heatpumps.

World Barley, Malt & Beer Conference | The malting industry and malting barley suppliers very much depend on the general beer output. However, the pandemic years 2020 and 2021 were a different case entirely, marked by full capacity utilisation, pull of demand, price pressure and a logistics crisis – not to mention the impact of the conflict between Russia and Ukraine. The World Barley, Malt & Beer Conference held by RMI Analytics, that brought the major players of the global supply chain together at the end of March, painted a varied picture of the challenges and opportunities.

Unrestricted hop trade | Plant protection regulations must be harmonized internationally if global trade in foods and their ingredients is to function smoothly. This was the demand made by Dr. Reinhold Kugel, Head of Product Safety and Quality Assurance for international hop specialist BarthHaas, at a thematic session held by the SPS Committee of the World Trade Organization (WTO) in Geneva on 22 March 2022.

Development of a methodology | TU Munich is currently investigating the physics of formation of gas bubbles in liquids prone to gushing. Part 1 of this two-part series of articles describes the theoretic fundamentals and the measuring instrument developed. Part 2 presents the results of experimental studies.

Hop cones

Hop extraction | In addition to pellets and CO2 extracts, total resin extract (formerly referred to as ethanol extract) is a well-established hop product that has been utilized for decades in the production of beer. In the second article of this two-part series, the properties of total resin extract are presented in alphabetical order and, where applicable, the latest research findings are included as well.

The Arbeitsgruppe Hopfenanalyse or AHA (Hop Analysis Working Group) has announced the mean alpha acid values determined in freshly harvested hops by mid-October 2021.

Hop addition | A number of studies are available on the behaviour of hop bitter substances during beer ageing and potential sensory repercussions; a survey can be found in “Hops – from Cultivation all the way to Beer” [1]. None of these studies tried to address the question whether changes in bitter substances differ between exclusively hot hopped beers and dry hopped beers. To investigate this question, a bottom-fermented test beer was late hopped and, in addition, part of the test beer was dry hopped. The beers were aged systematically and analysed.

Hüll aroma hops | The climate change brings particular challenges for hop growers and brewers. Aurum, the new Hüll aroma variety with a Tettnanger background, presents itself not just as a climate-tolerant noble hops but also with a fine-hoppy aroma in combination with a pleasant subtle bitterness and lives fully up to its name in numerous brewing tests.

Many challenges | At the beginning of November, the Maltsters’ Association of Great Britain (MAGB) held their Annual General Meeting in online format as the pandemic continues to restrict the ability to meet face to face. The Annual Luncheon was once again postponed but has now been firmly booked for next year when it will return to the Armourers Hall in London on 1st November 2022.

Short supply | The supply of spring malting barley in Europe remains tight. A smaller area and very heterogeneous qualities characterise this year's harvest.
