GlenDronach 50 Year Old – GlenDronach 50 Year Old is slowly matured in the finest Pedro Ximenez and Oloroso Sherry casks for at least fifty years.”The GlenDronach is of true Highland style: a heavy and robust spirit, perfect for a long maturation period in sherry casks. At The GlenDronach Distillery, we have carried forth the tradition of our founder James Allardice since 1826, maturing our whisky in the finest Spanish Pedro Ximenez and Oloroso sherry casks from Andalucía.We continue to work towards mastering the art of sherry cask maturation, and our Highland whiskies are recognized for their deep colour and rich flavour profiles, which range from sweet fruity flavours, from the Pedro Ximenez casks we select, to the dry and nutty notes, from superb Oloroso casks. Our well-kept secrets have been guarded for nearly 200 years by a parliament of rooks who love The GlenDronach so much they try to nest in the warehouses. The distillery folk believe as long as the rooks remain at the distillery, it will be good for the whisky.”
