This is the third bottling in Smögen's Sherry Project series, which sees their Swedish single malt whisky matured for longer amounts of time with each subsequent release. 1:3 is a 4 year old whisky which was distilled in July 2011 and finished for 14 months in a Sherry butt before being bottled at 53.7% ABV. 1:3 is a release of 666 bottles - a very interesting series from the small Swedish distillery.
