Founded in 2005, Walnut Block is the vision of brothers, Clyde and Nigel Sowman with Clyde in managing the overall project and Nigel responsible for the development of the estate’s organically farmed vineyards. The first vines were planted in 1996 on the alluvial deposits of the renowned Wairau Valley in Marlborough where the combination of free draining soils, sunshine hours and temperate climate provide an excellent backdrop for the production of high quality, cool climate grapes that have both natural intense fruit flavours and refreshing acidity. For the whites, the Collectibles Sauvignon Blanc is fermented in stainless steel whilst the Nutcracker Sauvignon is made 70:30 tank and barrel and the Nutcracker Chardonnay is fermented and aged in 500 litre demi-muids. Open top fermenters are used for the reds with further ageing in French barriques, 9 months for the Collectibles and 12 months for the Nutcracker.
