In 2002, Bruichladdich's master distiller Jim McEwan decided he wanted to create the peatiest whisky in the world, adding Octomore to its range range of unpeated (Bruichladdich) and very peated (Port Charlotte) whiskies. In addition to its extraordinary phenol content, Octomore is also characterized by an innovative approach to the blending and ageing of these spirits.

An Octomore single cask distilled in 2008 and bottled at cask strength in 2015 by Rest & Be Thankful, aged for seven years in a bourbon cask. Rest & Be Thankful is a bottler founded in 2012 by Eamonn Jones and Aidan Smith. It notably made a name for itself with its outstanding bottlings of Port Charlotte and Octomore. Its name comes from a 1753 inscription engraved in a stone left by soldiers at the summit of Glen Croe, which is particularly arduous to climb. A limited edition of 248 bottles.
