The North British Distillery is widely renowned for its consistent quality, yet it is the 34 years of maturation in a refill Oloroso sherry butt that lend this single grain whisky its extraordinary depth. Distilled on September 2, 1991, the spirit matured until January 2026 under the care of the renowned independent bottler Signatory Vintage. The result is a single-cask offering from the Cask Strength Collection—a remarkable rarity limited to just 442 bottles.

In the glass, the whisky displays a warm copper hue—achieved entirely without coloring—that reflects its long interaction with the wood. The nose is greeted by intense aromas of dark dried fruits and ripe plums, accompanied by a gentle honey sweetness. On the palate, the whisky’s 52.9% ABV strength unfolds with notes of rich caramel, delicate oak spice, and a characteristic nuttiness typical of premium sherry-cask maturation.
