Ardbeg Dark Cove is matured in ex-bourbon and "dark Sherry casks" for "The Darkest Ardbeg Ever". Those 'dark' casks provide plenty of oaky depth. Undoubtedly a terrific single malt - now discontinued.   Nose: Earthy and spicy, with bold notes of dark chocolate emerging against orange, treacle toffee, coffee and oak, a smoky background and a mysterious floral note. Palate:  The mouthfeel is almost tart, with raisins, dates, ginger and pepper spice. Finish: Long, spicy and rich with notes of toffee, coffee and tar.
