Founded in 2005, Walnut Block Wines is the vision of two brothers – Clyde and Nigel Sowman. By combining their experience in viticulture and the wine industry with their passion for fine wine, they have created a boutique winery that offers a unique range of superbly crafted, organic Marlborough wines. The estate takes its name from Marlborough's oldest walnut tree, which towers majestically above the Sauvignon Blanc vines – creating a special historical focal point for the vineyard.
