Boon Geuze Mariage Parfait has an alcohol content of 8%. It consists of 95% mild lambic, aged at least three years and specially reserved for this purpose, and 5% young lambic. The latter provides the fermentable sugars and wild yeasts. After mixing in a vessel of 25,000 litres, the wort (unfermented mixture) is filtered and chilled. If we are bottling, we bring it back to fermentation temperature. The bottles are placed in a climate-controlled space for the secondary fermentation. This is followed by maturing at low temperature for at least 6 months. The soft, mildly sour berry taste, harmonises with the oak barrels’ aromas in which Geuze Mariage Parfait has ripened. The body speaks of vanilla followed by a bitter aftertaste of cloves that becomes increasingly intense. Sublime.
