Octomore 14.2 is distilled from 100% Scottish mainland Concerto barley and is malted to 128.9 PPM. Instead of being matured in first fill bourbon casks, it is matured in a mix of Oloroso and Amarone wine casks, hailing from some of the most renowned wine regions of Spain and Italy respectively. The spirit is then brought together in French oak, adding depth and complexity to the single malt.
