Morrison & MacKay has been knocking it out of the park with a series of Old Perth single cask blended malts, and this one looks like another home run. It’s a 41 year old blended malt, which has been drawn from a single sherry butt. We agree, that’s proper old for a blended malt. Very impressive indeed. Only 515 bottles were produced. . A richly flavoured and coloured dram, all of components were distilled in 1977, aged for 41 years and bottled from a single sherry butt.
