Powerscourt Distillery and O Brother Brewing join forces to create this stellar release! Fercullen single malt barrels are filled with ‘Opus One’ imperial stout 12.5%. to get a whiskey influence and finished for a total of 17 months. Expect notes of rich chocolate ganache, fruit loaf, buttery popcorn with some dry spice and roasted malt. Only 800 bottles available.
