A Stornoway-born Glasgow publican is preparing to make whisky history by bringing home a cask of the first spirit to be distilled legally on the Isle of Lewis in more than 160 years.

Mike Donald, manager of Glasgow’s Sub Club and head of marketing for music bar MacSorleys, is setting off tomorrow on a 600-mile round trip to secure the only cask to leave Lewis free from the threat of the dreaded excise man since killjoy prohibitionists demolished the island’s sole distillery in 1844.

The “new make” spirit is only two years old, and will not officially become whisky for another 12 months, but a handpicked group of drinkers will be given a once-in-a-lifetime chance to taste the new dram when Mr Donald returns to the city on Thursday.

Made by the purpose-built Abhainn Dearg distillery in Uig, the Spirit of Lewis whisky, as it will be known, is described as “intensely floral” and “extremely drinkable” in its underage spirit form.

Drinkers should be warned, though, that at 65% abv, the new make spirit packs a punch that will take the breath away from even the hardiest of Scottish tipplers.

Mr Donald will be joined on his quest by colleagues Mike Grieve and Paul Crawford, the owners of MacSorley’s bar, and photographer Brian Sweeney, who will document the three-day journey.

The bar’s island-born marketing manager said it was fitting Abhainn Dearg should make its debut at MacSorley’s, a Glasgow bar with more than 100 years of heritage as one of the city’s best-loved Highland haunts.

“I’ve been doing a lot of digging about the history here,” said Mr Donald, “and the thing that kept coming up was that it was a real Highland bar, a home away from home for Highlanders.”

The owners of Abhainn Dearg – meaning “red river” in Gaelic – have agreed to release a 40-litre cask to MacSorley’s, which took its name from the publican who opened it in 1899.
