From Frank Boon Master Brewer: “Traditional geuze requires maturing in casks made of oak. The oak casks used at our brewery each have their own history and are characterised by unique microflora of wild yeast strains. Our bottles of Traditional Oude Geuze with cask numbers combine beer from one specific wooden cask (mono brew) with a very small quantity of young Lambic (blend) that will kick off the bottle conditioning process.”
