Celia Welch may be the most important winemaker that you’ve never heard of in Napa Valley, though devotees of high-quality boutique yount sb labelwineries know her work well. Welch is a consulting winemaker for Barbour Vineyards, Hollywood & Vine Cellars, J. Davies Winery, Keever Vineyards and Winery and Scarecrow Wines. She is the winemaker for Lindstrom Wines and owner and winemaker of Corra Wines. Despite her busy involvement in these producers, Welch has a new project called Yount Ridge, one of whose wines is our Wine of the Day No. 240. This is a limited edition bottling that My Readers will have to use their wiles to search out, but I know you’re up to the challenge. Grapes for the Yount Ridge Sauvignon Blanc 2015, Napa Valley, derived from an organically-farmed vineyard in the Oakville District AVA; the wine matured a brief four months in a combination of 70 percent stainless steel tanks and 30 percent new French oak, a judicious employment of wood, if you ask me. The color is pale straw-gold; a glorious, green, leafy bouquet encompasses notes of caraway and toasted hazelnuts, lemongrass and figs, smoked pears, thyme and tarragon. The wine is lively and spicy on the palate, animated by bright acidity coursing through a lovely talc-like texture bolstered by an edge of limestone minerality; a few moments in the glass bring in hints of white pepper and chives, lime peel and tangerine. The grapefruit-tinged finish is spare and elegant, chiseled from chalk, sea salt and flint. 14.2 percent alcohol. A beautifully-wrought sauvignon blanc for drinking through 2018 to 2020. Production was 160 cases. Exceptional. About $35.
