Ra Nui operates in Marlborough, New Zealand's South Island, where cool-climate conditions shape expressive Pinot Noir and rosé. The winery's Delta Hill Pinot Noir and core Pinot Noir bottlings demonstrate the region's capacity for structured, nuanced red wine—wines that have drawn assessment from Wine Spectator, Wine Advocate, Wine Enthusiast, Decanter, and Falstaff. A rosé blend of Shiraz and Pinot Gris rounds the portfolio, offering the aromatic brightness and dry profile characteristic of Marlborough's maritime influence. The winery's range reflects the South Island's signature precision and minerality, anchored in Pinot Noir's silky tannins and the region's ability to balance ripeness with acidity.
