Should the numbers on your malt COA be produced from a mash that's more similar to your brewery mashes? Did you know that's already happening when you buy UK malt? Listen up, then join the conversation (https://community.mbaa.com/communities/community-home/digestviewer/viewthread?GroupId=37&MessageKey=c1d189f2-57d6-4047-8b26-f993a3f04a11&CommunityKey=cb7fc054-5008-4b01-87f3-588d3c711e07&tab=digestviewer&ReturnUrl=%2fcommunities%2fcommunity-home%2fdigestviewer%3ftab%3ddigestviewer%26CommunityKey%3dcb7fc054-5008-4b01-87f3-588d3c711e07).

In today's competitive craft beer market, if you're standing still, you're dead. Continual improvement is a required survival skill. This episode tells the story of how Dogfish Head Craft Brewery went about reducing perceived mercaptan via fermentor trub removal. Read more at MBAA.com Special Guest: Joe Spearot.

Remember learning about Kveik back on episode 102 (https://www.masterbrewerspodcast.com/102)? This time, we catch up with the man who tracked down these yeasts and reinvigorated a traditional farmhouse brewing culture that nearly died out. You'll also hear about a time when it was illegal NOT to brew Christmas beer. Special Guest: Lars Marius Garshol.

The guy who explained how we narrowly avoided an American Reinheitsgebot on episode 174 (https://www.masterbrewerspodcast.com/174) is back with more surprises. This time you'll hear about the widespread use of malt substitutes in Germany, a beer war, and the birthplace of America's most popular beer style. Special Guest: Greg Casey.

We look back at the last 70 years of innovations in brewing, we look forward to what the future holds, and we hear a pint full of great anecdotes from an author with whom we're all familiar. Special Guest: Charlie Bamforth.

Tom Eplett (http://community.mbaa.com/network/members/profile?UserKey=b35e6b49-d001-4a8c-9b25-f244caade3d0) joins us to talk about some anecdotal fermentation problems, lessons learned, and his go-to papers, books, etc. for troubleshooting and learning about brewing. If you still think the best yeast is in the middle of the cone, you should listen to this episode. Special Guest: Tom Eplett.

This week, we continue our draught line cleaning discussion with Keith Lemcke. Special Guest: Keith Lemcke.

Draught beer line cleaning is a critical factor in the service of excellent draught beer. Cleaning your system frequently ensures beer quality but increases the cost of service due to beer lost when preparing the lines for cleaning. Throughout the industry, there is debate over the "best practices" in draught cleaning, including what defines a "clean" draught system. With the ever-increasing selection of draught beers, it is imperative not only to the brewer but all the way to the consumer that the beer provided as draught is representative of the beer provided by the brewer. The challenges of clean beer lines have never been more evident than today. Many of the draught beers on the market come with active yeast cultures, wild yeast cultures, and bacteria, all part of the flavor mix. These organisms can contaminate draught lines for the next beer to be tapped on those lines. Additionally, the intrusion of contaminant microorganisms from various sources and breweries needs to be eliminated and controlled withi

In 2018 Goose Island was plagued with a wild yeast contamination identified in post centrifuged products. This is how we systematically sought root cause, and ultimately eradicated the contamination despite our previous process understandings. Special Guests: Alex Nham and Joey Tidei.

It is well known that hop-forward beer styles exhibit tropical fruit aromas. These aromas are conferred by a range of hop-related volatile compounds, including polyfunctional thiols such as 3-sulfanylhexan-1-ol (3SH) and 4-methyl-4-sulfanylpentan-2-one (4MSP). These compounds are present at relatively high concentrations in hops and are extracted into beer during dry-hopping. Polyfunctional thiols are also abundant as non-volatile glutathione and cysteine conjugates in hops, and to a lesser extent can be found in barley (and therefore, malt). These conjugates are cleaved into amino acids and free thiols by enzymatic activity of yeasts, thus bound precursors may represent an important pool of tropical fruit flavor in beer, particularly in beer styles where dry hopping is minimal. In order to successfully liberate this pool of flavor, yeast with strong carbon-sulfur ß-lyase activity are needed. In wine research it has become evident that only a small number of commercial Saccharomyces cerevisiae starter culture
