Greywacke 2022 Marlborough Sauvignon Blanc was named #10 wine by Wine Spectator in 2023, so proprietor/winemaker Kevin Judd traveled to New York to present that wine during the New York Wine Experience. On the way to New York, winemaker Richelle Tyney stopped in San Francisco, Chicago and Boston to share back vintages of Greywacke Wild Sauvignon, proving the ageworthiness of this unique wine.
