Dewar's Double Double 26 Year Old is inspired by a process pioneered by Dewar's in 1901. Our Double Double Series has been aged, blended together, aged again, then finished in sherry casks for the ultimate smoothness. Finished in Palo Cortado sherry casks, this blend delivers heady, aromatic, floral notes with honeyed fruits, subtle spice, and the characteristic silky smooth finish.
