The family-owned Spy Valley was a bit out of the way, down a long, hot, sheep-lined road. Although Sauvignon Blanc, Chardonnay, and Pinot Noir are their main exports, winemaker Paul loves working with aromatics. Rieslings aren't normally poured, but once I told the tasting room attendant about my mission, she called up to the main office to have one brought down. Off dry, the Riesling had lovely, integrated acidity with ripe peachy and citrus flavors and a lovely stony finish. They only make about 7,000 cases (out of a total 120,000), so distribution is limited; I was grateful for a taste. The Gewürztraminer is what blew me away; luscious with a strong acid backbone, with a big floral nose and tropical flavors, this is their signature wine, and a delicious treat before the 4.5km ride home.
