Generations Mortlach 75 years old. On 17 November 1939 John Urquhart, the first generation of the family to be involved in Gordon & MacPhail, instructed the first-fill Sherry cask to be filled with new-make spirit from Speyside's Mortlach Distillery. Seventy-five years later, the cask was emptied. It has been nurtured and cared for by four generations of the family. It retailed around $30,650.00. Thank you Bonnie Scotland.
