Obviously Old Grand-dad Bonded knows a thing or two about classy whiskey: this is a magnificent version, even by its own high standards. It was always a winner and one you could bet your shirt on for showing how the small grain can impact upon complexity. But this appears to go a stage further. The base line is a touch deeper, so there is more ground to cover on the palate. It has been a whiskey-lover's whiskey for a little while and after a few barren years, has been inching itself back to its great Frankfort days.
