This is the first official release of a single grain whiskey from Irish Distillers. Method and Madness reinforce Irish Distillers’ “continued commitment” to experimentation and innovation at the Midleton Distillery. Single Grain Irish Whiskey Finished in Virgin Spanish Oak has been matured in ex-Bourbon barrels and finished for 12 months in toasted, virgin Spanish oak from Galicia. The process adds “complexity, cask character and a spicy note” to the liquid.
