Kahurangi Estate produces wines from New Zealand's South Island, drawing on the region's cool-climate conditions. The winery's Mt Arthur Reserve Chardonnay and Mt Arthur Reserve Riesling represent its focus on white varietals, with both wines rated by major critics including Wine Advocate, Decanter, Wine Spectator, Wine Enthusiast, and Falstaff. The estate also produces Montepulciano, extending its range into red wine. These three flagship offerings reflect the winery's approach to varietal expression across both traditional and alternative grapes suited to the South Island's terroir.
