Miljenko "Mike" Grgić (born April 1, 1923) is a Croatian American winemaker in California. He was born into a winemaking family in the town of Desne on Croatia's coastal region of Dalmatia. He is notable for being the winemaker behind the 1973 Chateau Montelena Chardonnay that bested several white Burgundy wines in the wine tasting event that became known as the Judgement of Paris. In recognition of his contributions to the wine industry, Grgich was inducted into the Culinary Institute of America's Vintner's Hall of Fame on March 7, 2008. The tribute came at the same time that Grgich was celebrating his 50th vintage of winemaking in the Napa Valley.
