The 2010 Kayena Vineyard Riesling has a moderately scented nose of grapefruit and pear juice with subtle notes of peach blossom and yuzu zest. Light bodied, dry and crisp, the youthful, tight-knit palate has great tension with a long steely finish. Approachable now, it should drink best 2012 to 2018+.

The 2008 Riesling Kayena Vineyard emits a perfume of mineral, biscotti, floral notes, and citrus. Dry, crisp, and tart on the palate, it could use an infusion of fruit. Drink it over the next 1-2 years. Importer: Robert Whale Selections, Washington, D.C.; tel. (202) 237-5200

The 2007 Kayena Vineyard Riesling is light straw-colored with an excellent nose of citrus, lemon-lime, melon, and floral notes.
