Listen "40: Joe O’Sullivan of Minden Mill Controls the Variables in Dry-Climate Whiskey Maturation"

Episode Synopsis

The romance of whiskey maturation meets environmental reality in many parts of the world these days—increasingly hot, dry climates can produce markedly different results than the humid environments of Scotland or Kentucky. That can leave distillers wrestling with the question of whether to lean into process- and environment-driven results, or to manipulate that environment to achieve intentional flavor goals.
For Joe O’Sullivan—master distiller at Minden Mill (https://www.mindenmill.com) in Nevada’s high desert, just east of Lake Tahoe—the choice is clear: to prioritize consistency through distillation and maturation processes, so that they can let their estate-grown grain shine.
In this episode, O’Sullivan and host Sydney Jones discuss:
the impact of terroir on grain, and on distilled spirits made from that grain
losing 3 to 4 percent angel’s share per month in a very dry climate
building a distillery to optimize intended flavors in finished spirits
identifying signature flavor characteristics and optimizing whiskey blends to highlight them
controlling the rickhouse climate to mimic weather patterns in popular distilling centers such as Kentucky and Scotland
And more.
