Wine of the Week: Greywacke, Wild Sauvignon 2013, Marlborough, New Zealand

Greywacke, Wild Sauvignon 2013, Marlborough, New Zealand

The winemaker behind the Greywacke label is one of New Zealand's most thoughtful and experienced practitioners (and ace photographer), Kevin Judd. I've ammassed a vertical collection of this wine - the Wild Sauvignon, fermented with wild yeasts and partly barrel-fermented - from 2009 to 2013 that I will be tasting and reporting on soon, for this is a Sauvignon Blanc that marches to a different beat. Fermented with wild yeasts and given a very long, slow and natural fermentation in mostly older barrels, it has intriguing nutty and honeyed nuances as well as ripe Ogen melon fruit and a little hint of Sauvignon herbaceousness. On the palate it is savoury and layered, complex flavours underpinned by a grapefruit juicy tang and length, in a powerful yet subtle interpretation of the style. Watch the video for my full review, including much more detail and food matching suggestions. Around £21.50, The Wine Society, AG Wines, Devine Fine Wines and see all retailers on wine-searcher.
