West Cork Black Cask Blended Irish Whiskey 750ml is a blend of grain (66%) and malt (34%) Irish whiskeys. It is matured first in first-fill bourbon casks for three years, then polish matured for an additional year in heavily charred bourbon casks. Bottled at 40% ABV, it aims for a robust character given its finishing offering char, oak influence, and a sweetness that balances the blend.
