Port Dundas 20 year old was distilled in 1990 & bottled in 2011 giving this single malt an age statement of 20 years. The Port Dundas 20 year old was matured in a combination of casks, firstly undergoing maturation for three years in refill, then in equal parts aged for 17 more years in either new American oak Bodega, new charred European oak or first fill ex-bourbon American oak casks. It has been bottled at cask strength & distilled from 100% single grain making it uniquely rare & because the distillery is now closed down this is an irreplaceable bottle of whisky.
