W.D. O'Connell 15YO Single Grain Irish Whiskey Oloroso Cask (62,5%)

With this 15-year-old Single Grain Irish Whiskey, W.D. O'Connell demonstrates how careful cask selection and patient maturation can elevate grain whiskey to remarkable depth. Distilled at Cooley Distillery, the whiskey initially matured in ex-bourbon casks before spending a further four years in refill Oloroso sherry casks.

This combination of bourbon and Oloroso influence adds structure and complexity, with elegant grain notes complemented by the rich, nutty character of sherry wood. Bottled at natural cask strength (62.5% ABV), without chill filtration and with no added colouring, the whiskey retains its full, authentic character.

This limited release was awarded Irish Single Grain of the Year 2025 at the Irish Whiskey Awards — a testament to both craftsmanship and quality. A powerful and characterful Irish whiskey for lovers of intensity, maturation depth and true cask strength bottlings.
