When I visited the distillery in 2009 this was my favorite of the three expressions we sampled after the tour.  The nose is sweet, cherry cola, sherry, cocoa and prickle of alcohol (this is bottled at 46% ABV).  The taste is sweet with caramel and a fruity, plum or fig note, overall reminscent of christmas pudding with brandy sauce.  The finish is leathery and warm then dries out with sherry and slightly bitter note right at the end (maybe the only oaky note in this expression which is surprising for a 15 year old).  With water there is more orange in the taste and  more oak (even woodsmoke) in the finish.
