General Session and Workshop Presentations
General Session & Discussion Panel: Challenges to Barley
MBAA President Rob McCaig kicks off the first day by taking a look at the challenges to barley, and he brings together the experts to have a full-blown discussion! Join the conversation as panelists examine topics, including barley crop status from the United States and across the globe, supply strategies to address the current crises, and brewing strategies to address a changing supply. What better way to get your mind ready for a full day of learning!

Workshop: High-Gravity Brewing: The Case for Sustainability and the Challenges
This workshop will focus on the practical method of high-gravity brewing. The reasons a brewer may choose to begin high-gravity brewing need to balance with the risks involved. Discover the "ins and outs" of high-gravity brewing and what a brewer needs to be mindful of on this quest. Topics to be discussed include the effect on raw material usage (especially yeast) during high-gravity brewing, mass balance of energy usage of high-gravity brewing vs. brewing to spec, and practical issues of high-gravity brewing.
