Redbreast 15 Year Old is a single pot still Irish whiskey produced by Irish Distillers. One of the most popular whiskies in the core Redbreast range, the 15-year-old is matured in oloroso Sherry casks and ex-Bourbon barrels. Triple-distilled, this is a classically rich, complex whiskey, its mellow fruit and spice character amplified through longer maturation.
