Walnut Block is the vision of two brothers, Clyde and Nigel Sowman, who have joined together to create a range of wines reflecting their collective experience and passions. As of 2010, the winery is practicing organic and will receive certification in 2013.
Situated in the renowned Wairau Valley, Walnut Block Wines takes its name from the landmark walnut tree within the vineyard itself. The 17 hectare vineyard is located on the Wairau Valley plains, a dry ancient river bed which has created a prime growing area for great wines, particularly intense aromatic Sauvignon Blanc.
Walnut Block sources all of its grapes from its privately owned vineyard, which has been established for 10 years. Only the best parcels of grapes are selected to make Walnut Block Wines. The vineyard lies on soils ranging from shallow stony soils to alluvial sand and clay giving a great scope for developing the complexity that Walnut Block wines show.
