Sherry Oak Casks

HP0003

The majority of the Scotch whisky industry uses ex-bourbon barrels for maturation. At Highland Park, bourbon barrels are not routinely filled. Traditional oak casks are used; butts, puncheons or hogsheads – no barrels – all seasoned with dry Oloroso sherry, which contribute to the distinctive richness in the resulting whisky. Spanish oak casks seasoned with sherry give colour, spice and dried fruit character, whereas American oak sherry seasoned casks give lighter, sweeter vanilla and butterscotch flavours. Sherry oak casks are far more expensive but the view at Highland Park is that they are worth it for the rich character and natural colour they provide to the maturing spirit.
