Bushmills 21 Year Old is a rare whiskey which is in scarce supply with only a limited number of casks in their warehouses. It’s matured in bourbon and sherry barrels for 21 year, before being married together for two years in a madeira-infused cask. The result is dark chocolate and carmelised toffee aromas and a sip that clings to the palate before releasing a magical burst like mint. It’s a rare taste in every serve.
