Glendalough Double Barrel is an Irish single grain whiskey bottled at 42% ABV and finished in Oloroso sherry casks. Single grain whiskey is often known for a lighter, smoother style, making it approachable for newer drinkers.
The Oloroso cask influence typically adds extra richness, with notes often associated with dried fruit, gentle spice, and oak layered onto the spirit's softer grain character. Overall, this is a style that balances easy-drinking texture with a touch more depth from the sherry finish.
