Here's what customers have said about older vintages:
1982 Cluster Select Riesling "I just wanted to let you know that we recently served the '82 at a dinner party to rave reviews.....it was spectacular with a white chocolate cheesecake with passion fruit. We will savor the 5 remaining bottles but they won't last as long as the previous ones!!!" -N.H. 9/6/2011
1985 Cluster Select Gewürztraminer "Just a quick note about a half bottle of your wine we found in the back of a closet. It had been forgotten all this time. We opened it last night and it was fantastic. Basically liquid gold. It took some of the sting out of watching the Lakers lose." H. W. M. -6/14/2010
1983 Cluster Select Riesling "We opened a bottle last night with visiting friends from England who happen to be lovers of dessert wines. The Riesling was dark amber in color and absolutely incredible - great depth of flavor and perfect balance between sweetness and acidity. (Our friend David described it as "the nectar of the Gods".) What a wonderful treat. My guess it has another 10 to 20 years ahead of it at least." -P & J D. 8/1/2007
"Even in blind tastings in the United States, one sip is enough for tasters to murmur, "Navarro." No other West Coast winery ... produces such impeccably balanced sweet wines, with their blazing, refreshing acidity in perfect harmony with the lush, honeyed fruit."
