Oude Quetsche Tilquin

This a 6.4% ABV spontaneous fermentation ale from Gueuzerie Tilquin in Rebecq, Belgium. They take and blend beers from other Belgian breweries, in this case mixing lambics (brewed with wild yeasts) that are one, two and three years old. This beer is unpasteurized, unfiltered, and refermented in the bottle. It ferments with purple plums.

The beer pours a hazy light brown and pink salmon in color. There is a short, and short-lived, head of white to off-white bubbly foam.  There is a powerful aroma, tart, fruity, sour, plums, earthy, with some woodiness. The taste is a powerfully tart sourness, with some unripened plum; damp, fresh earth; and woodiness. They must have used some very tart plums in this, I think it is possibly even more sour than their guezue.
