Knappogue Castle 21 year Single Malt Irish Whiskey is a premium whiskey aged for 21 years, distilled in copper pot stills and made from 100% malted barley. It is produced in limited quantities by the Knappogue Castle Whiskey Company, and is named after the 15th-century castle in County Clare, Ireland, where it was first discovered. This whiskey is matured in ex-bourbon barrels, then finished for a short time in oloroso sherry casks, resulting in a rich and complex flavor profile with notes of vanilla, honey, dried fruits, and oak. With its smooth and luxurious finish, Knappogue Castle 21 year Single Malt Irish Whiskey is a must-try for any whiskey connoisseur.
