From the Overeem website - 'This port cask matured single malt whisky was finished to taste in a deliciously fresh and chocolatey ex-stout cask supplied by a local, independent, Tasmanian brewery. Presented at natural cask strength for authenticity of flavour and maximum stout influence, this enticing, complex and unique single malt whisky from Overeem Distillery can be thoroughly enjoyed on its own, yet pairs perfectly with your favourite dark ale'.
