A limited edition, natural cask strength Single Grain Scotch Whisky. The oldest ever Special Release to date. The smallest Special Release since the very first. From Port Dundas, a historic grain distillery that closed quite recently. A second release in this series from the original distiller’s stocks. The fourth single grain release in this series. From refill American Oak hogsheads filled in 1964. Interesting to compare with the 20yo released in 2011, which was largely aged in highly active casks. Only 752 bottles worldwide.
