This deep dark intense imperial stout has been aged for 10 months in rare American oak bourbon barrels that previously held New Zealand Whiskey Co. single malt for more than 20 years. Packaged 2017. Best before 2025. There was a very limited number of New Zealand Whiskey Co. barrels and Kereru can soak the whiskey out of a barrel into a beer only once. (After that first use, the barrel may offer oak flavour, but the whiskey flavour is gone.) We produced a scant 1500 bottles of this very rare beer.
