Caramel, vanilla, sweet almond paste, charred casks, some sherry influence (?). A nice kick mid-palate with cracked black pepper that extends into the finish, before getting drowned out by the sweetness again.
I wager this has a pretty high malt whisky content; the Glenrothes components for one are hard to miss.
Even in the finish, there's no distinct grainy or bitter note. Amazing value for money!
