For seven years now, a limited special edition of the Black Forest Rothaus Single Malt Whisky has been released at the end of each calendar year. The special feature is the cask types that are used to finish the spirit, which is initially matured in ex-Bourbon barrels. This year, friends of the popular Black Forest whisky can look forward to single malts with a finish in Portuguese Madeira and French Banyuls sweet wine casks.
