Grave Digger Tunes of War is a single malt whisky from the St. Kilian distillery, which was bottled in honour of the German heavy metal band Grave Digger, founded in 1980. Many of the band's albums pay homage to Scottish history. The limited edition malt whisky has been distilled from heavily peated barley malt (54 ppm) from the Scottish Highlands and then matured in 225-litre ex-red wine casks.
