The Redbreast release is a limited-edition 1989 single pot still Irish whiskey, initially matured in ex-Bourbon barrels but recasked to a Duoro port cask in 1995. The release from Highland Park is a 2003 single malt, bottled after 16 years maturing in a single first fill sherry butt.
Of the releases, Billy Abbot, content and training manager at The Whisky Exchange, said: "They're an excellent pair of drams, showcasing what excellent casks can do."
