Whether it's maltose-negative yeast, arresting fermentation before the alcohol production phase, or other novel methods, this panel discussion focuses on the various ways that brewers successfully convert wort to non-alc and low-alc beer.

Panelists include:
Dr. Peter Bircham, Head of Research & Development, Garage Project Dr. Peter Bircham serves as the Head of Research and Development at Garage Project and holds the position of Associate Research Fellow at Victoria University of Wellington. Working at the crossroads of academic and industry research, Peter specialises in enhancing industry-relevant yeast traits through non-GMO methods. His expertise encompasses high-throughput phenotyping, breeding and directed evolution strategies, with a particular focus on yeast development for non-alcoholics and novel flavour profiles

Jordan Childs, Chief Brewer, Mash Gang Jordan's approach to NA brewing has tapped into the wider world of food science, and he's been on a quest for many years to create the perfect NA brews with all the tools in the brewing and beverage toolbox. If there's a fermentation method, he's tried it—from maltotriose-negative yeast to arrested fermentation and more. What's he found is that there is no single way to make great NA beer, so he matches process to the particular beer style to achieve the best results.
