We recognize that the kings of Napa Valley are cabernet sauvignon and merlot, while the queens are chardonnay and sauvignon blanc, but the storied region is home to a spectrum of interesting and intriguing grapes, especially in the white category. Think, for example, of the rieslings produced by Smith-Madrone, Trefethen and Stony Hill. Perhaps an improbable grape for the region is the Rhone variety grenache blanc, yet here is our Wine of the Day, the Priest Ranch Grenache Blanc 2016, Napa Valley, made all in stainless steel from grapes grown on the Somerston Estate at an elevation of 1,250 feet in the Vaca Range that defines the area’s eastern boundary. This is one of the palest wines I have encountered, its hue as ineffable and pure as water; distinct aromas of lemon balm, peach and spiced pear are woven with notes of straw and heather, while after a few minutes in the glass hints of dried honey, jasmine and bees’-wax emerge. The wine is clean, precise and dry on the palate, crisp and vibrant yet offering lovely balance between litheness and a soft, almost talc-like texture; it’s the sort of contrast that makes a wine exciting to drink. Flavors of roasted lemon, peach and melon are inextricably melded with bright acidity and a burgeoning element of limestone minerality; the finish is bracing in its marsh grass-sea breeze austerity and seashell salinity. 14.6 percent alcohol. Drink now through 2018 or ’19 with seafood risottos, seared salmon or swordfish or as a scintillating aperitif. Production was 1,271 cases. Winemaker was Craig Becker. Excellent. About $22.
