This whisky's sherry seasoned heritage and luscious richness is the inspiration for its name, meaning ‘dark’ in Spanish. The Macallan Oscuro is drawn exclusively from oak casks seasoned with Oloroso Sherry. An exceptionally high proportion of these are first fill, which endow the whisky with a rich, deep colour and intense flavour. When the casks are at the peak of maturation, the whisky is gently reduced to 46.5% alcohol by volume with natural spring water drawn from boreholes deep under The Macallan Estate. It is then matured in slumbering casks for at least six months, allowing the flavours to ‘marry’ and harmonise. It undergoes no further strength reduction and is non-chill filtered at ambient room temperature before being bottled for your enjoyment.
