The Octomore Edition 12.3, also known as "The Impossible Equation," is a single malt Scotch whisky from the Bruichladdich distillery, located on the island of Islay in Scotland. This particular edition is from the 2015 vintage, made from barley harvested in 2014 from the Church Field at the famous Octomore Farm. The barley, a variety called Concerto, was grown by farmer James Brown.
This whisky is known for its high peat level, measured at 118.1 ppm (phenols per million), making it a heavily peated Islay whisky. It was matured for five years in a combination of ex-American bourbon casks (75%) and Pedro Ximenez Solera casks from Jerez bodega Fernando de Castilla (25%).
The maturation process took place in two separate stages, with 75% of the whisky aged in ex-American whiskey casks and 25% in PX Solera casks. This edition is not chill-filtered and does not contain any artificial coloring. The alcohol by volume (ABV) is a powerful 62.1%.
This dram offers a burst of sherry, fruit, and of course, smoky flavors. It is a true representation of a heavily peated Islay whisky, made from locally sourced barley and matured on the island. The combination of ex-bourbon and PX Solera casks gives it a unique flavor profile, making it a must-try for whisky enthusiasts.
Clearly a favorite from the 12 series, it is really complex and the barrel aging with Sauternes goes down well in the glass. A little water reveals a whole new layer of sweetness and wine notes, enhancing its complexity.
