The Sour Hour | Episode 118

The artistic and technical challenges of producing small-batch, barrel-aged sour beers define the creative philosophy at Cellador. Kevin Osborne emphasizes an "art project" approach to brewing, prioritizing experimentation over traditional business constraints. The discussion highlights the use of unconventional ingredients like smoked peaches, charred squash, and wine grapes, alongside the technical necessity of maintaining mixed cultures and managing barrel-aging processes. The conversation underscores the importance of high carbonation and the strategic use of aged hops to achieve complexity and dryness, moving away from the "flabby" acidity often found in early American sour beer production. The episode also reflects on the rapid evolution of the American sour beer scene over the past decade, driven by homebrewers and craft brewers pushing boundaries through collaborative experimentation and technical innovation.
