The 2018 Cabernet Sauvignon from Cathy Corison is another absolutely classic wine and yet another legend in the making. The wine is just a whisper higher in octane than the Sunbasket cabernet, tipping the scales at 13.8 percent alcohol and offering up all of the precision, purity and structural sophistication that one has come to routinely expect of young vintages of Corison cabernet sauvignon. The lovely bouquet wafts from the glass in a polished blend of black cherries, sweet dark berries, tobacco leaf, Rutherford Dust, cigar smoke and a deft framing of spicy new oak. On the palate the wine is pure, full-bodied and seamlessly balanced, with a beautifully refined attack, a rock solid core of fruit, exemplary soil signature, ripe, buried tannins and great focus and grip on the long, complex and perfectly balanced finish. This is a stunning young wine! 
 
Corison Winery is a small family winery in St Helena, California, founded by Cathy Corison in 1987. Predominately a Cabernet Sauvignon house, Corison's wines are elegant and notably ageworthy, and are held in high regard.
Cathy Corison developed a passion for wine in the 1970s, while studying biology at Pomona College in Claremont, California. After receiving a Masters in Enology at UC Davis, she worked at Chappellet Vineyard, Staglin Family Vineyard, York Creek Vineyards, and Long Meadow Ranch, while launching Corison.
Corison label wines
In 1987 she began producing varietal Cabernet Sauvignon with fruit sourced from vineyards on benchland between Rutherford and St Helena. The Corison Napa Valley Cabernet Sauvignon is sourced from three vineyards; Corison also produces two estate single-vineyard bottlings from Kronos and Sunbasket vineyards, both certified organic.
Helios and Corazón
Corison also makes small quantities of estate Sunbasket Vineyard Cabernet Franc under the Helios label. The Corazón range features Gewürztraminer from Moon Mountain in Sonoma, Riesling from Wirz Vineyard in Cienega Valley, and a St Helena Napa Valley Cabernet Sauvignon Rosé.
Over the years a handful of other one-off lots have been crafted by Cathy under one of the Helios, Corazón or Acappella banners.
