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.
Raw materials
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.

Yakima Chief Hops | Yakima Chief Hops (YCH), a 100% farmer-owned global hop supplier, is pleased to announce the pre-sale of their 5th Annual Pink Boots Blend in partnership with Pink Boots Society (PBS). PBS is an international nonprofit with a mission to assist, inspire, and encourage women in the fermented and alcoholic beverage industry.

Aging behavior | During experimental trials conducted to assess the reproducibility of the 2 hl pilot brewery at Hopfenveredlung St. Johann GmbH, it was determined that a number of hop aroma compounds were transferred from hops to beer. Subsequently, the behavior of these compounds in the finished beer over the course of aging was investigated [1].

Transfer of aroma substances | In search of a characteristic hop aroma in dry hopped beers, the potential of the hop variety Eureka! was investigated in more detail in brewing tests. This investigation focused on time-dependent transfer of selected hop components.

Wet milling | The malting and the brewing industries are in a constant need of saving money, energy and lowering their carbon footprint. What if maltsters could skip the most energy consuming step of nowadays malt production, i.e. the kilning process? And what if brewers had a workable process to mill the green malt? This article presents an introduction to brewing with green malt with an innovative wet milling system comprising two sequential mills, the first being used for cutting and the second for crushing.

Malting barley report | In addition to a smaller acreage of spring barley in Europe, there are now heterogeneous harvest results. Prices are showing a firm trend.
