Whisky Jameson Stout Edition Caskmates Series. Irish Whisky, craft beer barrels. Like all the best conversations, the one between Jameson’s Head of Whisky Science and the Head Brewer of a local craft beer brewery, started at the bar. A swapping of whisky and beer barrels soon after, resulted in Jameson Stout Edition – triple-distilled, blended Irish Whisky that has been patiently finished in Irish craft beer-seasoned barrels.
