Firestone Walker Sour Opal

We’ve patiently waited for two years to offer you this exquisite ale! Sour Opal retraces its roots to the lambic cellars of the town of Brussels and the Senne River valley, in Belgium. This American “Gueuze” represents a spectrum of flavors from a traditional barrel aged sour ale, complete with aromas of aged cheese and a distinct earthy mustiness that can only be found in a well cellared barrel aged sour. The complexity and balanced flavors of Sour Opal can be attributed first to the crisp assertive tannic acidity of the Viognier barrels.
