Epic and Hallertau are two of the most influential breweries in New Zealand when it comes to hop-driven, American-style IPAs. Both breweries turn 20 this year and their respective founders, Luke Nicholas from Epic and Steve Plowman from Hallertau, talk about the early years of the hop revolution when they created two special beers: Armageddon and Maximus; as well as starting the Malthouse West Coast IPA Challenge and changed the way we thought about IPA.
