Ron Pattinson joins us to talk about his latest publication in the MBAA Technical Quarterly. Abstract: Through research in German-language technical publications, such as brewing textbooks and chemical journals, this paper has assembled considerable information about German sour beer styles. Much of this material has never been available in English before, and the author has personally translated them from German. This paper will discuss information on the brewing techniques employed in producing these mostly extinct beer styles and details such as the original gravity and alcohol content. This latter information mostly comes from 19th century German chemical journals, which often published chemical analyses of German beers. This material demonstrates how many sour styles there once were in Germany and how common they were in some parts of the country. Links:  MBAA TQ: German Sour Beers of the Late 19th Century

What happens at the intersection of art and science in brewing? The Brewing Summit's keynote speaker is widely recognized for the highly imaginative and experimental beers that he has produced in his 22+ years in the brewing business. While he considers himself more avant-garde in his approach to brewing, he has long understood the role of perspective and great fundamental science as being an integral part of the flavors he chases as he knows, those who ignore the science of brewing are destined to fail. Join Tomme as he discusses his brewery operations and how art and science work together in tandem to produce world-class beers.

Magdalena Oehlschlaeger discusses a novel brewhouse design which produces higher fatty acid and zinc concentrations, reduced wort aeration, higher yeast cell growth, faster extract degradation, and altered production of higher alcohols and esters.LINKS: MBAA TQ:  Influence of Altered Wort Composition on Selected Parameters of Fermentation

The Food Safety Modernization Act (FSMA) is the biggest overhaul of US food safety laws in over 70 years. The smallest breweries are supposed to be in compliance in September 2018. Tatiana Lorca and Doug Hindman explain how to comply, where to go for resources, and who to ask for help when it comes to making food safety part of your brewery's culture.LINKS: Brewers’ Responsibilities and Obligations under the U.S. Food Safety Modernization Act (FSMA) Food Safety Modernization Act: Insights for Brewers Submit a question to the MBAA Food Safety team

Is that sour beer also gluten-free? Brett Taubman explores the topic of producing gluten-free/reduced beers with lactic acid bacteria.Links: MBAA TQ: Microbial Gluten Reduction in Beer Using Lactic Acid Bacteria and Standard Process Methods Special Guest: Brett Taubman.

If you use Brettanomyces in your brewery, you know that counting brett cells is complicated. Leo Chan joins us to discuss the development of a method to automate cell counting of Brettanomyces.Links:  2018 MBAA TQ: Monitoring Brettanomyces Concentration, Viability, and Pseudohyphae Percentage During Propagation and Fermentation Using the Cellometer X2 Image Cytometer 2016 MBAA TQ: Measuring Lager and Ale Yeast Viability and Vitality Using Fluorescence-Based Image Cytometry 2016 MBAA TQ: Measuring Glycogen, Neutral Lipid, and Trehalose Contents in Yeast Using Fluorescence-Based Image Cytometry Related slide decks

Hollow Fiber Membranes can be used for carbonation or nitrogenation of beer, production of deaerated water, and for oxygenating wort in breweries of any size. Mimi Cartee and Todd Rausch join us to explain the technology. View the poster at MBAA.com Special Guests: Mimi Cartee and Todd Rausch.
