Slane Irish Whiskey takes many of its complex and smooth qualities from our signature Triple Casked process. Whiskey is aged in three varieties of casks: Virgin and Seasoned casks raised by hand at the venerated Brown-Forman Cooperages – and Oloroso sherry casks by way of Jerez in Spain. Once the liquid has been aged to perfection, it is masterfully blended to create an exceptional Irish whiskey.
