Their hops are home-grown, and their water comes from the mountain range that is the backbone of the South Island (the Southern Alps).
One of the most unique things about this beer was the texture. The bubbles didn't have a creamy foam like most stouts; instead, the bubbles were harder and they reminded me of the kind of bubbles that occur in root beer. The aromas were complex and powerful-- coffee was pretty strong, cacao came through more on the palate, and oatmeal contributed mostly to texture.
