Oude Geuze Boon is one of the finest examples of the traditional 100% spontaneous fermentation Lambic style. To moderate the sourness, Boon Brewery only brews Lambic in the 7 cold months, from early October until April, according to the traditional “turbid mash” system. This Lambic beer is aged for 1, 2 or 3 years in oak casks. The blend, a mild average 18 months old Lambic (unsweetened, unfiltered, unpasteurised) is refermented in the bottle and can be stored up to 20 years. Brewed in Lembeek, the village that gave Lambic its name. Awards at the World Beer Championships: 2008 Gold, 2010 Silver, 2012 Gold Medal.
