Port Dundas 35 Years Old 1978 Cask #0375 (Jack Wiebers Whisky World)

Bottled by Jack Wiebers Whisky World, this Port Dundas single grain, a 35 year old from 1978, drawn from cask 0375 and bottled at 59.7%. Only 120 bottles were released. Port Dundas was a giant of Lowland grain whisky, built in 1811 above the city of Glasgow and brought to an end in 2010. It stood on the highest ground in the city, its chimney visible for miles.

Made from a wheat mash drawn on Loch Katrine water and run through the distillery's continuous Coffey stills, this is a smooth, low flavour spirit built for long ageing. It was matured in a first fill ex-Bourbon cask, the refill wood letting the spirit's sweetness show. Three decades and more leave a concentrated, oaky grain of real rarity, mellow and fine. Refill oak, having given its sharpest compounds to an earlier fill, works slowly and lets the spirit lead.

At cask strength 59.7% it is muscular. Lignin gives vanilla, oak lactones lend a soft coconut, and a creme brulee and butterscotch note, atop the creamy grain make. Water is rarely needed, the spirit already soft and open. The finish is long, sweet and softly oaky. This is a relic of the city's great grain distilling age.
