I wasn't sure what to expect as I walked into the massive Opus One winery a few weeks ago. The opportunity to survey an estate’s entire production is not something that happens every day. At this level, wines can express so much; the spirit of the people involved, the characteristics of where they are from, and the personality of a vintage. Opus One is among the most famous wines in Napa Valley, but quality has been up and down over the years. How would the wines show? Well, that was answered loud and clear a few hours later.
