Some supply chain crises are acute. A bottleneck at the ports. A shortage of semiconductors. These can get fixed, to some extent, with concerted policy choices. But other crises are slower moving and don't have one easy fix. In the coming years, the bourbon supply chain could be under threat, due to a shortage of the specific type of wood used in the barrels made for aging the liquor. On this episode of the podcast, we speak with Penn State University forestry professor Calvin Norman about a looming shortage of critical white oak. He explains why the industry is potentially facing a shortfall, why other woods can’t be used to replace it, and what it would take to ensure that this critical tree remains abundant.
