Master Brewers Podcast

Richard Preiss discusses his work with genetically unique yeast used to produce Norwegian farmhouse beers known as kveik.Links: Characterization of kveik, Norwegian Landrace Brewing Yeast (2018 MBAA ETC) Traditional Norwegian Kveik are a Genetically Distinct Group of Domesticated Saccharomyces cerevisiae Brewing Yeasts (Frontiers) Special Guest: Richard Preiss.

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

What's better than learning from your own mistakes? Learning from other people's mistakes, of course. This week on the show, practical tips & lessons learned the hard way from Andy Tveekrem, who is here to help you make better beer. Special Guest: Andy Tveekrem.

Eric Warner has been bottle conditioning beer since before some of you were born. Eric discusses different methods and his experiences. Link: Eric's webinar Link: The original Deschutes process Link: Bottle Conditioning Panel

How can you assure quality from small-scale hop growers? Who better to answer this question than a small-scale hop grower like Josh Mayich.

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.

No brewery is too small to take a systematic approach to quality. Gary Nicholas has some great advice for aligning your breweries priorities, data collection, and decision-making process. This week's content was curated based on a listener request. Special Guest: Gary Nicholas.

Inefficient extraction. Beer loss. These are problems that have to be solved, even when centrifuging dry-hopped beer. Alyce Hartvigsen is looking for dry-hoppers to trial Alfa Laval's prototype Iso-Mix External Drive Rotary Jet Mixer. 

Andrew Fratianni explains how isinglass works, how to optimize results, when and why to use auxiliary finings (such as silica solutions), and more.

During the MBAA Brewing & Malting Science Course, students are put into groups to work through hypothetical scenarios. The winning case study is then published in the Master Brewers Technical Quarterly. Simon Nielsen joins us to talk about the approach his group took during the 2017 course.

Have you ever noticed that diacetyl seems to rear its head more often in hoppy beers? Is dry hopping to blame? Kara Taylor & Devin Tani from White Labs join us to discuss a presentation given during the 2017 Master Brewers Conference.

Understanding the basics of yeast propagation is critical for commercial brewers of all sizes. With 50 years of experience researching yeast, Graham Stewart joins us to talk about the basic principles of brewer's yeast propagation. Special Guest: Graham Stewart.

Jordon Geurts joins us from Briess Malt & Ingredients to give us a behind-the-scenes look at product development for malted, naked oats, which can be used to enhance mouthfeel or to produce gluten free beers. Special Guest: Jordon Geurts.

John Giarratano talks yeast pitch rates, how to manipulate esters and higher alcohols, and other fundamentals for the craft brewer.

Nick Mader is on a mission to eliminate "black box syndrome" in regards to mixed culture fermentations. Learn how inoculation rate impacts esters and phenols.
