The Macallan malt whisky is matured excluvisely in sherry oak casks from the bodegas of Jerez, Spain. The Spanish oak casks are hand-picked annually. Described by Paul Pacult, the renowned international whisky writer, in his book Kindred Spirits as: "simply the best 12 Year Old single malt around", The Macallan has justly reaped such critical acclaim. The secret of The Macallan lies in defiant adherence to traditional methods and ingredients. The continued use of finest Golden Promise barley and the insistence on the finest oak casks are just two of the pre-requisites for perfection.
