New Yeasts, New Beers: Non-GMO Technologies for New Beer Flavours (Part 3)

DESIGNING YEAST | In this concluding section of our three-part series (part 1 and 2 see BRAUWELT International No. 5, 2018, pp. 354-356 and No. 6, 2018, pp. 430-432) we outline the various non-GMO methods by which new brewer’s yeast are being created to drive beer flavour and aroma innovations. By applying the classical technique of selective breeding – used for millennia in the
domestication of species – it becomes possible to re-imagine brewer’s yeast, thereby enhancing and expanding yeast’s natural ability to define beer styles and flavours.

ANTON CHEKHOV famously wrote, “Knowledge is of no value unless you put it into practice.” In the last two articles in this series, the importance of yeast to the final sensory profile of beer was highlighted, an examination was made of how yeast produce these compounds, and an overview was provided of how brewers can modulate environmental, chemical and biological factors to produce the beers they desire. Sometimes however all the knowledge in the world is useless unless it is applied correctly. When it comes to beer that means starting with the right Saccharomyces yeast. Sometimes Mother Nature is kind and the right choice is already out there. If not, however, Saccharomyces yeast strains can be built from the ground up using classical, non-GMO yeast development techniques.

New Yeasts, New Beers: Non-GMO Technologies for New Beer Flavours (Part 2)

CONTROLLING YEAST | In the first part of this three-part article (BRAUWELT International No. 5, 2018, pp. 354-356), we outlined the enormous impact yeast has on the flavour and aroma profile of beer. In this second part, we discuss the variables and methods by which brewers can exert direct control over yeast during the brewing process. In the concluding article, we will examine the timehonoured, non-GMO classical development techniques by which new and exciting yeasts are being developed to help create whole new flavour and aroma profiles in beer.

OF ALL THE INGREDIENTS that contribute to a beer’s makeup, Saccharomyces yeast is quite simply the only one over which brewers have total control. While the selection and application of the right hops and malt is certainly important, in reality it is the farmer and maltster who ultimately control the growing conditions and final product quality of these ingredients. This means that brewers must put some faith into factors outside the brewery’s purview.

New Yeasts, New Beers: Non-GMO Technologies for New Beer Flavours (Part 1)

DESCRIBING FLAVOUR | Continuing our series on the topic Better Yeast, Better Beer, here we provide the first part of a three-part article explaining yeast’s significant potential in developing revolutionary new beer tastes and flavours to meet rising consumer demands for innovative beer tastes. In part two, we examine the many variables that brewers can exploit to modulate yeast impact on beer flavour and aroma. And finally, in part three, we explore the idea of developing novel brewer’s yeast strains, using classical non-GMO techniques, to help deliver better yeasts for better beer.

EXPERIENCING BEER has become a refined art for today’s savvy beer drinkers. Terms like “hoppy” have been replaced with descriptors such as “menthol”, “floral”, “citrus”, “woody aromatic” and “cream caramel”, to name a few. In fact, the palates of some beer enthusiasts are probably sophisticated enough that they could moonlight as professional sensory panelists. The divide between enthusiast and professional has narrowed remarkably, with many passionate beer drinkers ultimately starting up their own successful breweries.

The art and science of brewing has also become increasingly complex. While at its core brewing beer has remained unchanged for thousands of years, the modern brewer has at their disposal a deeper scientific understanding of brewing and fermentation, as well as advances in brewing technology that allow for precise control of the multitude of biological, environmental and chemical factors at work in the makeup of
a beer.

And brewers need every bit of help they can get, too. As the beer industry (specifically the craft market) matures, so does the beer consumer. The beer consumer today not only has a more cultivated palate but also, and importantly, a greater level of direct engagement with breweries via social media and beer ranking websites.
