Boon Oude Geuze 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. Boon Oude Geuze is brewed from 40% unmalted wheat, 60% of barleymalt, aged hops and wild yeasts collected from our coolship and 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.
