Craft beer went through (as did I) a keepsake / cellar phase but when you talk Bourbon the shit gets real weird and in Dusty Booze: In Search of Vintage Spirits by drinks writer Aaron Goldfarb you get story after story of the hunt for old bottles of you name it, whiskey, tequila, rum, and even chartreuse.
I heard Goldfarb talk about “dusties” on the Bourbon Pursuit podcast and the stories are wild so I am heading to my local library to order.
