Sauvignon Blanc is New Zealand’s signature grape, with many quality offerings readily available on retail shelves and restaurant wine lists around the world. But that wasn’t the case when Kevin Judd became the founding winemaker at Cloudy Bay in 1985, or even when he established his own winery in 2009. And now his Greywacke Sauvignon Blanc Marlborough 2022 is Wine Spectator's No. 10 wine of 2023.
