Raw materials
Amino acids in malt | Availability of assimilable nitrogen supply is usually determined by measuring free amino nitrogen (FAN) in malt. However, amino acid composition in the resulting wort may vary substantially between barley varieties, hence impacting on yeast fermentation and beer flavor profile and stability through Strecker degradation. For optimization, and in particular when susceptible beer styles are involved, a balance of amino acid levels and composition in malt is therefore the subject of research.

Pilot-scale study | Dry hopping is applied to produce many different beer styles with varying alcohol contents. Information about the alcohol-dependent behaviour of hop components after dosing is necessary to understand interactions and to ensure consistent beer quality. A pilot-scale study was therefore performed using standardised procedures by only varying the beer’s alcohol contents from 0.5 % to 10.5 % alcohol by volume (ABV) at constant dry hopping rate.

Latest BarthHaas Report | It is always eagerly awaited, and on 25 July 2023 the time had come again: as part of an online press conference, hop trader BarthHaas from Nuremberg presented its report 2022/2023 with the latest figures on the world hop and world beer market.

Europe | The weather conditions in spring 2023 are expected to lead to quite heterogeneous spring barley harvest results in Europe, with weak and very heterogeneous screening, cause by drought in many regions of Europe this spring. Weak protein values also characterize the first batches.

IHGC in Ljubljana | This year’s hop meeting from June 25 to 29 in Ljubljana broke all previous records: with over 80 participants from 15 countries, 36 talks and 20 posters, it was the best-attended event staged by the Scientific-Technical Commission of the International Hop Growers’ Convention (IHGC).

15th Trends in Brewing | Since the last Trends in Brewing in 2018, our world has changed dramatically. In view of the pandemic and the war in Ukraine – with its far-reaching consequences – the title of the 15th Trends in Brewing International Malting and Brewing Symposium, held in Ghent in Belgium from 2 – 6 April 2023, was extremely fitting: Brewing in a challenging world – producing quality and affordable beers in a world with scarcity.

Beer ageing | During the malting process, malt modification is influenced by targeted adjustment of germination parameters (technological factors). The level of precursors in the malt, formed during malting, makes a significant contribution to beer ageing. This article describes, in particular, the precursor potential, formed from non-enzymatic degradation of polysaccharides.

Hardly any change expected | The acreage for spring barley in Europe this year is expected to be about the same in total as last year. However, spring barley sown in autumn is becoming more and more important.
Logistics
Global service provider | In the last thirty years, with its wealth of expertise family business Schwarz Logistik in Nuremberg has earned itself an excellent reputation in hop logistics and in the transportation, storage and import and export of hop products. To mark its 40th anniversary, BRAUWELT talked to managing director Susanne Schwarz and her husband Christian Schwarz-Baumann, the man responsible for hops at Schwarz Logistik.

Quality and innovation | Sugar Creek Malt is an outstanding example of a craft malting facility where the maltsters are resolved to make a product exhibiting true value through a combination of stamina and conviction. BRAUWELT author Sylvia Kopp visited the micro-malthouse in the US state of Indiana where she met the founder who is as down-to-earth as he is creative. In the eight years of its existence, the malthouse has enriched the brewing industry with its innovative approach.

New approach | Our growing global population requires more food, but we have limited land available. Besides, the changing climate increases deviation of crop quality, leading to downgrades and threatening food safety and security. Optimizing the use of what is produced from our fields will be more and more important in the future, even crucial, from a sustainable and economic standpoint. The Swedish agri-tech company BoMill offers a new approach to grain sorting based on the individual kernels’ inner properties. The article presents the technology applied to malting barley or wheat and describes how such technology can benefit the malting and brewing supply chain, with a focus on expanding markets or areas that may not yet be fully structured to grow barley.
