Brewed specifically for the Jameson Caskmates program, O’Reilly’s Extra is a more robust version of our Dry Irish Stout that was finished in Jameson whiskey barrels. O’Reilly’s Extra is a rich, smooth stout accentuated by sweet caramel and vanilla notes imparted by the former Jameson vessels. Unlike our standard O’Reilly’s Stout, this beer is served on CO2 to allow the full character of the beer to shine through. 6% ABV.
