Beringer continues to do everything right. Its staff of talented professionals may rank as the best in the business. Beringer's Chardonnays take advantage of the rich, opulent fruit the warm growing climate and rich soils provide. Since 1991, the top Chardonnays have been 100% barrel-fermented and put through a malolactic fermentation. Both the Private Reserve and Proprietor Grown Chardonnays have soared in quality, with exceptional vintages in 1991 and 1992.No tasting note for the 1990 Private Reserve Chardonnay.
