Two-Buck Chuck is used to beating competitors in price, but now it appears its beaten rivals in taste, winning bragging rights to best California chardonnay at the state fair?s commercial wine competition.

Although full results from this year?s competition aren?t yet publicly available, wine industry sources confirmed that the 2005 Charles Shaw vintage was the highest scoring chardonnay in a blind tasting by judges who reviewed wines without regard to price.

The wine is made by the Bronco Wine Co., based in Ceres, and is sold mainly by Trader Joe?s.

Most of the Charles Shaw brands sell for $1.99, giving the line of wines their two-buck chuck moniker.

Wine industry leaders said the double gold medal rating for Charles Shaw?s Chardonnay is likely to prompt a rush of sales before official announcement of results July 12.
