Arran Signature Series Edition 3: Duero Discovery – The third release in Arran’s much-loved Signature Series, personally selected and signed by Distillery Manager Stewart Bowman. This 12-year-old unpeated single malt spent its first six years in bourbon barrels before being finished in red wine casks from Spain’s Duero River region. The result is a rich, ruby amber whisky with layers of vibrant fruit, oak and spice.
