“…No clear difference was observed between ‘CDC Goldstar’ beer and ‘CDC PlatinumStar’ beer for aldehydes, esters, foam stability, THOD, or T2N. Both varieties lacked the LOX-1 enzyme and therefore the beer produced maintained its freshness in these trials, as observed in our previous trials ( Hoki et al 2013 , 2018a , 2018b ).…”

“…Sapporo Breweries has released several LOX-1-less malting barley varieties in Australia and Japan, as well as in Canada, and showed that the LOX-1-less trait is effective in all types of genetic background ( Hoki et al 2013 , 2018a , 2018b ). The earlier LOX-1-less varieties were based on backcross breeding, which implies that the basic characteristics of those varieties were similar to their recurrent parents.…”

“…Pilot- and commercial-scale brewing trials revealed that T2N and THOD content in aged beers made from ‘CDC PolarStar’ malts were reduced by approximately 1/2 and 1/3, respectively, compared to beers made from the control malts without affecting any other beer characteristic ( Hoki et al 2013 ). Sapporo Breweries has also released LOX-1-less barley varieties in Australia (‘SouthernStar’) and Japan (‘Satuiku 2 go’) with backcross breeding ( Hoki et al 2018a , 2018b ). Furthermore, another LOX-1-less barley variety ‘New Sachiho Golden’, originated from a different mutant, has been developed to improve beer qualities in Japan ( Oozeki et al 2017 ).…”

Various types of malt quality profiles have been investigated to benefit the North American brewing industry. Herein, we report the development and brewing quality of the hulled, two-row malting barley ( Hordeum vulgare L.) variety ‘CDC Goldstar’ lacking lipoxygenase-1 (LOX-1-less). This new variety offers a novel malt type for the improvement of beer flavor stability. The agronomic performance of ‘CDC Goldstar’ was tested in the Western Cooperative Two Row Barley Registration Trials during 2013–2014. In addition to high lodging tolerance, the new variety showed 6% higher yield than the current leading variety ‘CDC Copeland’. The malt quality of ‘CDC Goldstar’ showed higher diastatic power and lower wort β-glucan content than ‘CDC Copeland’ and controllable proteolytic modification (soluble nitrogen and Kolbach Index). Pilot- (100 L) and commercial-scale (5,000 L) brewing trials were conducted using ‘CDC PlatinumStar’, another LOX-1-less variety with a low enzymatic profile, as the control variety. Absence of the LOX-1 trait from ‘CDC Goldstar’ maintained trans -2-nonenal levels in aged beers as low as those in other LOX-1-less varieties without affecting major beer parameters, such as ester and aldehyde content or foam stability. The newly developed ‘CDC Goldstar’ malting barley provides added value for the beer industry and consumers.

“…One of the most important components of such type, which was found in all the analysed malt samples, is (E)-2-nonenal (trans-2-nonenal). It is a compound with a very low taste threshold and is responsible for so-called 'cardboard off-flavour' in fermented beverages 20,21 . Higher concentration of this component might be the result of oxidation of lipids and fatty acids, various Strecker degradations, aldol condensation of short chain aldehydes or secondary oxidation of long chain aldehydes, but data gathered in this study cannot precisely pin-point exact mechanism 19 .…”

Wheat malts are necessary to produce wheat beers. In this study, wheat was grown with addition of seed meals into the soil, to determine whether such agricultural practice could improve the quality of the grain and, therefore, improve the quality of wheat malt produced from these grains. It was determined, that malt produced from the grains of the winter wheat cultivated with the use of seed meals is characterised with improved technological properties, such as saccharification time, filtration time and extract content and some of the seed meals had a positive impact on the content of various volatile compounds present in the produced malts.
