The Balvenie bottles 25-year-old single malt

The Balvenie has introduced a 25-year-old single malt, aged in traditional American oak casks.

Each cask used to produce the single malt has already been used to mature whisky, and will produce a spirit of subtle spices and honeyed sweetness.

No more than 300 bottles of the Single Barrel Traditional Oak will be filled from any one cask and all will be labelled with the distillation date, bottling date and cask number. The bottles will retail at £400.

The Balvenie malt master David Stewart said: "Over the course of my time at the distillery, I've sampled thousands of casks and this means I know what to expect when our spirit is matured for many years solely in traditional American oak casks. This allows me to pick out the casks of whisky that display the expected rich, sweet and slightly spicy character I'm looking for.

"But of course there will always be subtle difference between the whiskies from different casks, and I know that more and more drinkers appreciate this and will enjoy the experience of drinking this single-cask whisky."
