This 100 imperial proof release was bottled in 2015. The single malt is produced at an undisclosed distillery however there is plenty of discussion that this is whisky from Caol Ila distillery on Islay. The whisky has been matured in ex-bourbon casks and even though there is no stated age to the whisky it is believed that this whisky has been matured for 7 years.

Speciality Drinks was established in 1999 as the independent bottling arm of The Whisky Exchange, which launched its online retail site the same year. Their first bottlings were under the Single Malts of Scotland label in 2005, followed by the Elements of Islay range and this Port Askaig single malt brand in 2006 and 2009, respectively. The company was renamed Elixir Distillers in 2017.
