Master Brewers Podcast

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...

Cans have become the primary packaging type in the U.S. craft brewing scene. While cans are a near-ideal package for maintaining the quality of the beer, it's important to understand the seaming process and how to diagnose and fix issues with the seamer. Failing to do so will lead to tremendous damage to brands and consumer confidence in canned craft beer. This presentation will focus more on the...

The 2020 World Brewing Congress is almost here! Have you registered yet? Special Guest: Keith Villa.

A growing demand in utilizing biotransformation, a general term for the conversion of compounds through biological pathways, to improve the organoleptic profile of beer has changed the way hop forward beer recipes are approached. While the analysis of terpene biotransformation has been well documented, there remains a gap in knowledge in sulfur compounds due to their extremely low concentrations (...

Biotransformation has become a buzzword in the brewing community, with many brewers even performing dry hopping at certain specific times to hit what is considered to be the “biotransformation sweet spot.” Academic literature does not support these claims. With the aid of enzymes developed for the wine industry, two experimental IPA beers were brewed: one with an enzyme preparation aimed at hydrol...
