Having turned her hand to the plant-based milk du jour, oat aficionado Morgan Maw explains to The Spinoff how one grain is doing its bit for New Zealand. “I am – like so many people – very passionate about New Zealand and our landscape and what’s happening here, especially with farmland and our land use,” she says. “Oats require no irrigation, they’re really gentle on the land, they’re good for our soils and soak up lots of nitrogen.” Early this year, an oat milk shortage brought two things to light: that we rely on a global supply chain for our oat milk, and that New Zealanders absolutely froth the stuff.
