Cardhu sits above the village of Knockando on a Speyside ridge that gave it the name Carn Dubh, the black rock. Helen Cumming began distilling here in 1811 and her husband John took out a licence in 1824, after the Excise Act made legal distilling possible at last. Her daughter-in-law Elizabeth rebuilt the distillery in 1884 and sold its old stills to William Grant, who used them to start Glenfiddich. Cardhu was bought by John Walker and Sons in 1893 and has been the malt heart of the Johnnie Walker blend ever since.
The Special Cask Reserve is a no-age-statement bottling matured partly in toasted oak casks intended to add a softer, vanilla-forward sweetness to the house style. It is bottled at forty per cent, with the smooth, easy character that Cardhu has always traded on. The toasted oak does its work without bullying the spirit: there is a little more spice and vanilla than in the standard twelve, but the same gentle Speyside outline.
Cardhu has always been an entry point. It was famously the distillery that, in 2003, Diageo briefly relabelled as a vatted malt under the same name, prompting the row that led to the modern category rules for single malt and blended malt. The distillery learned its lesson and the single malt range has stuck to its lane since.
This bottling is true to that lane. It is a polite, well-made introductory Speysider, designed to be drunk easily rather than studied closely.
