Wairau River produces wines from Marlborough, New Zealand's largest and most celebrated wine region. The winery's Reserve lineup demonstrates the region's signature intensity and precision across multiple varietals. The Reserve Syrah expresses the dark fruit and structural power that Marlborough's warm, sun-exposed sites impart to this varietal. The Reserve Pinot Noir captures the elegance and complexity for which the region has become known. A Reserve Botrytised Riesling rounds the portfolio, showcasing the region's capacity for both dry and sweet expressions of this aromatic grape. Marlborough's cool maritime climate, long growing season, and free-draining soils create conditions that concentrate flavors while maintaining acidity—characteristics evident across Wairau River's reserve selections. The winery's wines have been assessed by Wine Advocate, Decanter, Wine Spectator, Wine Enthusiast, and Falstaff.
