Spontaneous fermentation beer obtained from the fermentation of destoned fresh purple plums (variety Prune de Namur or Quetsche véritable d’Alsace, close to the Damson) in a blend of 1, 2 and 3 years old lambics for a period of 4 months. Unfiltered and unpasteurized, it is re-fermented in the bottle for a minimum period of 3 months. The taste is slightly tart but also fruity and round which makes this Quetsche à l’ancienne may be more accessible for non-experts. It also has a slight dryness from the skin of the plums. The nose perceives a plum brandy perfume.
