Deep dives

Climate impact on barley quality and supply chain consequences

Climate change has caused a shift in the standard quality of barley crops in North America, resulting in high protein levels, pre-harvest sprouting, and other challenges. As a result, the supply chain has been forced to adapt sourcing strategies to minimize the impact of these changes. The variation in crop years requires brewers to be prepared for unpredictable harvest and growing weather and to manage the diverse quality of the barley they receive.
