Located up the road from a US government listening post (hence the name), Spy Valley is one of Marlborough’s most acclaimed wineries. It’s no secret that Marlborough Sauvignon Blanc is one of the world’s favourite wines, and this family-run winery is known for its textbook, terroir-driven Sauvignon Blanc. But they don’t stop there, and chief winemaker Paul Bourgeois and his team are also experts in producing brilliant aromatic whites, including Riesling and Pinot Gris.
