I am averse to making a limited edition product the Wine of the Week because it just ain’t fair to My Readers. On the other hand, the Cornerstone Stepping Stone Corallina 2013, Napa Valley, is that rare rosé of such character and quality that I don’t want you to miss it, though it must be marked Worth a Search. Made completely from syrah grapes given a long cool fermentation in stainless steel tanks and aged five months in neutral French oak, this wine is designated Napa Valley, but it’s made from dedicated grapes grown in the Crane Ranch Vineyard in the Oak Knoll District. The color is that true coral, what the French call “eye of the partridge,” and while I’ve never looked a partridge in the eye, I’ll take their word for it. Aromas of strawberries and peaches are highlighted by orange zest, a hint of dried thyme and rosemary and a touch of flint; a few minutes in the glass unfurl a note of tobacco-leaf earthiness. The structure feels incisively chiseled from limestone, and there’s a deep cut of bright acidity under a texture lent suppleness and clove-like spice by the brief exposure to wood; all of this supports tasty and juicy yet spare strawberry and red currant flavors. Alcohol content is 13.1 percent. Winemaker was Jeff Keene. Production was 417 cases. Excellent. About $25.
