Greywacke (pronounced ‘grey-wacky’) is the name given to the grey sedimentary rock that characterises much of the soil in this estate’s vineyard. The winery was founded in 2009, and is the brainchild of Kevin Judd, former winemaker of Cloudy Bay for 25 years. The Greywacke portfolio is primarily based on two varieties, sauvignon blanc and pinot noir, the sauvignon blanc being produced in two distinctly different styles. In addition to this core range of three wines, there are also limited edition releases of chardonnay, and three aromatic varieties – pinot gris, riesling and gewurztraminer.
Subtle scents of snap peas mark the nose of the 2019 Sauvignon Blanc. There’s passion fruit as well, plus pink grapefruit and a slight crushed tomato-leaf component. It’s similarly complex on the palate, where it’s medium-bodied, with a strong core of grapefruity acids that give it backbone and length. [91 Points, Joe Czerwinski – March 2020, robertparker.com]
