Greywacke was created in 2009 by Kevin Judd who was the chief winemaker at Cloudy Bay for 25 years. The name 'Greywacke' was adopted by Kevin for his first Marlborough vineyard located in Rapaura in recognition of the high prevalence of rounded greywacke river stones in the soils of the vineyard, a sedimentary rock which is widely found in Marlborough. Kevin Judd is also New Zealand's finest wine photographer and has recently published a book 'The Landscape of New Zealand Wine'.
The fruit for this wine was grown at the organically-farmed Ashmore Vineyard in Fairhall, adjacent to the mouth of the Brancott Valley on gravelly clay-loam soils, conditions more typical of the Southern Valleys than the Wairau plains. The 17 year old vines were trained on a two cane VSP (vertical shoot positioning) trellis and careful shoot and bunch thinning was carried out. All Greywacke wines are produced from vineyards that are accredited to the Sustainable Winegrowing New Zealand (SWNZ) program and most of the vineyards are in conversion to become certified organic.
The grapes were hand-picked at moderate ripeness levels and were whole bunch pressed using a very low maceration press cycle. The resulting juice was cold-settled, then racked to fermentation vessels. Half of the juice was inoculated in a stainless steel tank using cultured yeast and the balance was filled into old French oak barriques where it was allowed to undergo spontaneous indigenous yeast fermentation. Towards the end of fermentation all the wine was transferred to a stainless steel tank where the fermentation was stopped, retaining 20 g/l residual sugar. The blended wine was then put in old barrels where it remained on yeast lees for a further five months before bottling in December.
A virtual fruit salad of mandarin segments, white fleshed peaches and crisp apples, sprinkled with lemon blossom and a dollop of honey. A lively, aromatic off-dry style that delivers a sherbet-like balance of bright, natural acidity and a subliminal touch of sweetness.
