Fermentation/Maturation
Testing the rule of thumb | The average beer drinker is still usually not familiar with the concept of original gravity or original extract. It is a common rule of thumb though that the ratio of 2½ (original extract, OE divided by the alcohol, as ABV) would be “about right” in most bottled beers. The authors have decided to find out in what way the rule of thumb factor of 2½ holds true and have, during the course of this investigation, discovered links to attenuation and inferred drinkability especially in lager type beers. These concepts were also checked against the portfolio of beers produced by Schilling Beer Co., a craft brewery situated in the northern part of New Hampshire, USA.

Yeast breeding | Renaissance BioScience Corp., a leading global bioengineering company based in Vancouver, Canada, is pleased to officially announce the publication of a landmark paper on lager yeast development in the February 2021 issue of Applied and Environmental Microbiology (Volume 87, Issue 3).
Fermentation/Maturation
Enzymes | In November 2020, Kerry, the international Taste & Nutrition company from Ireland, released a technical report detailing the results of a sustainability life cycle assessment (LCA) conducted on Kerry’s range of brewing ingredients and enzymes (a study already mentioned in BRAUWELT International no. 5, 2020, pp. 348-351).

Hard Seltzer | Omega Yeast®, known for custom propped liquid yeast pitches, announces the November release of Propper Seltzer™, a yeast nutrient for non-malt, sugar-based fermentation. Propper Seltzer nutrient is compatible with any strain of yeast including beer yeast, champagne yeast, wine yeast and distillers yeast, and was designed to make things easier for brewers looking to create their own hard seltzer.

Fermentation cellar extension | Exceptional beers require extraordinary design. Retrofitting new outdoor tanks and process technology at the Jopen Brewery near Amsterdam has created new opportunities for further developments in beer production while simultaneously increasing process reliability.

Yeast research in focus | Please note: in the April 2021 issue of BrewingScience, we will focus on yeast once again. The 3rd BrewingScience Yeast Special will be published on April 30, 2021. All researchers working in the field of brewing yeast research are invited to submit their scientific articles by Monday, 11 January 2021, at the latest.

Dealcoholization | In August of 2019, “Ghost Ship 0.5 %”, a pale ale with strong citrus notes brewed by the British brewery Adnams in Southwold, UK, sailed back to the island nation with the gold medal it earned at the World Beer Awards. The award rounded off a year of meticulous product development with the new GEA AromaPlus dealcoholization system.
Fermentation/Maturation
Kokumi-activity | Insight into the biochemical forces governing beer maturation has been lent further support by the “kokumi-active” conjecture. A further objective was to innovate a more time-efficient maturation process which replicated the flavour-enriched outcome of traditional lagering. The proposal is that pressure fermentation may lead to such a solution.
Fermentation/Maturation
Over-attenuating yeast | At the turn of the century, hardly anyone in Germany was familiar with this yeast. Nowadays, Saccharomyces diastaticus has virtually become a household name, especially among craft brewers. Some use it to brew novel beers in the style of those from Belgium. Others, however, fear this yeast and despise it as a beer spoiler, conducting extensive analyses to detect the merest traces of its presence in an effort to eradicate it in their breweries.
Fermentation/Maturation
Traditions and opportunities | There are many different ways for producing sour beer, ranging from modern kettle souring to traditional long term mixed fermentation. This article describes the most important souring methods, emphasizing opportunities to diversify the portfolio of sour beer styles.
Fermentation/Maturation
Lallemand | Expanding even further the “We Brew With You™” concept, LalBrew® Verdant IPA yeast is the result of a collaboration between Lallemand Brewing and Verdant Brewing Co, a craft brewery focusing on IPAs and modern hop-forward styles.
