Bowmore 12 Year Old Sherry Oak Cask is a beautifully balanced Islay single malt that marries Bowmores signature gentle peat smoke with the layered richness of Oloroso sherry maturation. Matured for 12 years in a combination of first-fill Oloroso European oak sherry casks and American ex-bourbon barrels, then finished in Oloroso sherry casks to deepen flavor and complexity
