Bourbon has to be aged in barrels, by law; whiskey usually spends years in barrels, by custom; and between 20-30 percent of wine spends some time in one. And almost all of those wooden vessels are made from just two kinds of tree: American white oak and French oak. This episode, we tell the story—and try the whiskey—of the distiller and the barrel-maker who, together, are figuring out how to use the huge, elegant, native oak of the Pacific Northwest to create new flavor, and, in the process, restore an ecosystem that has nearly vanished. Along the way, we figure out the science behind how a barrel affects the taste of what you sip, and we trace the trajectory of barrels from their pinnacle, as the go-to container for everything from fish to petroleum, to their current niche status. Finally, we explore why oak became the default wood for barrel-making—and meet the coopers experimenting with different woods, and an entirely new flavor universe for booze.
