Pearpawsterous by Upland Brewing Co. is a barrel-aged fruited sour ale, judged as BJCP Category 28C, Wild Specialty Ale. This beer's aroma is tart and fruity, with a low, pleasant mustiness. As it warms slightly, it takes on more depth and the tartness becomes more distinctly lactic. It pours hazy orange in color with a tall, fizzy white head. The head flattens fairly quickly, but bubbles continue rushing to the surface. This beer has a moderate lactic tartness in the flavor with fruitiness to match. The fruitiness creates an impression of sweetness, though it finishes well attenuated and dry. It is highly carbonated with a medium-light body, making it feel refreshingly crisp. Overall, this is a solid and well-balanced example of the style.
