Cascade Brewing The Vine
Aroma: “Sour grape juice up front with medium tart notes. Sweet fruity character with some earthiness.”
Flavor: “Grape and tart lactic flavor, with some muskiness. The moderate tartness transitions into a medium grape note. Nice grape character with acidic lactic tartness. Very high carbonation with high alcohol adds to warmth in the finish.”
Overall: “Slightly over-carbonated. Nice grape flavor balanced with acidity. All the flavors present themselves one after another and then leave a grape-juice note as a linger. The grape character and the lactic tartness blended well to give a nice lactic grape sour beer.”
