Green Spot is an Irish Single Pot Still whiskey comprised of 7 to 10 year old spirit. These have been aged in 1st fill bourbon casks, refill bourbon casks and ex sherry casks. There are some special edition bottlings that incorporate wine cask matured whisky for extra complexity. Different from Scottish Single Malt Whisky, Irish Single Pot Still Whiskey is made using a percentage of unmalted barley in the process, which affects fermentation, leading to an oilier mouthfeel and richness. Green Spot is made in the famous Middleton distillery.
