Sonoma County’s Alexander Valley is named for 19th Century settler Cyrus Alexander, who lends his given name, in turn, to the flagship red wine from Alexander Valley Vineyards. The winery CYRUS_2012_bottlegoes back to 1962, when Maggie and Harry Wetzel purchased a large portion of a homestead built by Cyrus Alexander. They planted grapes the following year and produced their first cabernet sauvignon in 1968, as a private project. By 1975, however, the family had built a small winery, and matters took off from there. Alexander Valley Vineyards is operated now by the third generation; winemaker is Kevin Hall. The Cyrus 2012, Alexander valley, is a blend of 76 percent cabernet sauvignon, 12 percent merlot, 7 cabernet franc, 3 petit verdot and 2 malbec. It aged a total of 24 months in French oak barrels, 12 months before blending and 12 months after. The color is dark ruby-purple from core to rim; loads of graphite, iodine and iron encompass a pinpoint focus on black currant, black cherry and blueberry scents and flavors that unfold notes of plum pudding and red velvet cake, lavender, licorice and bittersweet chocolate. If all of these factors sound like a confusion of aims and a tendency toward sweetness, that’s not at all what I mean. Yes, the wine gushes with ripeness, but it also is governed by dense, dusty tannins, swingeing acidity and a rigorous granitic mineral element. Some moments in the glass bring in hints of dried rosemary and sage (with the slightly resinous character of those herbs) as well as a tantalizing tinge of wild berries and meadow flowers. 14.3 percent alcohol. Drink now through 2022 to ’25 with steaks, pork chops, venison and braised meat dishes. Excellent. About $65.
