Most of what I prefer are Sonoma or Napa Chardonnays. Flora springs, stags leap, Wente, grgrich, Ferrari-carano. The Costco Sonoma is not bad. Cabs i like are Hall, Duckhorn, Robert Mondavi, flora springs. Some are more consistent than others. Price isn’t an indicator of quality that’s subjective. If a wine is outstanding though would you sell it for 5$ or 50$? Granted Some of its marketing.
