Master at Irish Whiskey Masters in 2021, 2022, and 2023 so it's no surprise why this is one of our all-time favourite Irish Whiskeys! This 100% heavy pot still whiskey has a high sherry ageing percentage. Redbreast was a brand name for Jameson's pure Irish pot still, bottled in bond by Gilbeys. First made in 1939 with Jameson filling Gilbey's own casks. Two sherry casks were used for each bourbon cask.
