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. Oak-derived flavors and aromas mingle with guava, passion fruit, pineapple and tart cherry notes. This beer rounds out with a crisp clean and quenching acidity as well as a mild grape fruitiness that is intensified by a higher carbonation level.

nuplastikk (5031) - Madison, Wisconsin, USA - MAY 30, 2015
Top notch US sour. Lots of yeast depth. Not sticky, thick, leathery. Easy going for the ABV. The yeast is well incorporated, Really comes together well, closer to a Belgian feel than most US sours. Lots of awesome tropical fruity tones. Pretty excellent stuff.

Smell is light sourness, brett, and dough. Taste is pretty much the same. Low carbonation, medium creamy body, and very mild foam.

Marheb (3037) - San Diego, California, USA - MAR 7, 2015
(En fût chez Firestone Walker Barrelworks): Un liquide très complexe avec ses notes mentholées, sa poussière, sa rusticité, son côté vineux franc et croustillant et son volet acétique. Certains aspects rappellent la Cantillon Classique mais le profil reste très américain, savoureux.

[ Tap ][ 4oz ][ FW Barrelworks ][ $2.50 ][ Tasting Snifter ][ 2.22.15 ]
>> Sour Opal. Clear orange pour, wispy white foam, effervescent. Nose is more funky than the other sours on tap at today, mild mildew oddity that isn’t the first time to rear its head in the tasting room today, tamarind, salted tomato, tamarind bean. Sharply sour beginning, lemon water end. As it warms up, this beer cleans up quite nicely to be more lambic-esque with leathery red grapefruit, sharp lime acid, oak, and tamarind bean. Sharply acidic throughout, but mostly citric/lactic. More aggressive than Feral One and more lambic than any of the others. Quite impressive.

Pour on tap at the brewery, hazy yellow-golden pour with white head, aroma brought notes of tart lemon, oak, earth into a bit of white wine, more funky, cheesy notes into a bit of bretty earthy notes as well. Taste is a mix of earth, grass, bread, white wine, hints of funk into a bit of brett, cheese, tart lemon, finishing tart, funky.

Tap @ Barrelworks. Slightly hazy yellow pour with a scattering of white foam. White wine like grapes with clean sour and tart notes in the aroma. Taste is quenching sour with apple and tart notes and some sharper acidic notes. Clean and dry mouthfeel. Impressive sour.
