Scotch By Nino Marchetti / January 31, 2020 The Glasgow Distillery Company, back in 2015, unveiled a new older series of Scotch single malt whiskies known as Prometheus. At the time it was a 26 year old expression. Now, in 2020, we are seeing the final in this bottling in the form of a 30 year old.The new Prometheus 30 Year Old, according to those behind it, is a three decades old Scotch single malt whisky that’s been aged in sherry butts and also influenced by peat. It’s been bottled at a cask strength 51.8% and is non-chill filtered.“We are immensely proud of the success of the Prometheus series over the last five years,” said Glasgow Distillery Company CEO and co-founder, Liam Hughes, in a prepared statement. “The launch of Prometheus 30 is both a celebration but also a bittersweet moment as it is the very last expression in the series. Once Prometheus 30 Year Old is gone, it’s gone.”Prometheus 30 Year Old (image via Glasgow Distillery Company)This Scotch, of which just 544 bottles are being released for sale through the distillery, is presented in a decanter with a heavyweight metal stopper and housed in a presentation box, each containing an individually numbered booklet.
