GlenAllachie's Cask Strength series is bottled in numbered batches, with each batch drawing on a different selection of casks from the inventory Billy Walker has built since acquiring the distillery in 2017. The whiskies in the series are all 10 years old, all bottled at full strength, and all presented without chill filtration or added colour. Batch numbers move upward with each release, and the series has become one of the more closely tracked cask-strength programmes in Speyside.
Batch 9, released in 2023, was drawn from a combination of Pedro Ximenez puncheons, Oloroso hogsheads and virgin oak casks, bottled at 57.1%. The PX component gives the batch its darker, sweeter centre of gravity, while the Oloroso provides the drier nutty backdrop and the virgin oak adds the fresh spice and tannin that stop the sherry from dominating entirely.
The nose is immediately heavy: treacle, black cherry and espresso, with dark chocolate and a clean line of toasted oak. The palate is thick and chewy at full strength, carrying the raisin and fig weight of PX alongside a firmer leather and clove note from the Oloroso. The virgin oak surfaces in the mid-palate as clove and cinnamon, pulling the sweetness back into balance. A few drops of water open up a darker, drier expression, though the whisky is perfectly drinkable neat.
The Cask Strength series has consistently outperformed its price point, and Batch 9 is a typical example: a decade-old sherried Speyside bottled honestly, at strength, with no cosmetic adjustments. It does exactly what Walker's reputation suggests it should.
