With Box Single Malt American Oak, the guys at Box distillery in Sweden, wanted to explore how the tastes of quercus alba can influence the flavour. The American White Oak (Quercus alba) is by far the most common species of oak in the modern whisky making industry. American casks became dominating in Scotland after the prohibition when the land owners, the owners of oak, together with the coopers union succeded to push through a law that stated american whiskey (bourbon) only to be matured in virgin oak. The result was that lots and lots of used casks were shipped over the sea to Scotland.
100 % peated whisky that first have been matured on 130-litres bourbon casks for 4.5 years, then finished for 8 months in 40-litres casks made of charred virgin american oak, the staves has been air dried for 26 and 45 months. Box American Oak is neither chill-filtered nor coloured.
