SAN FRANCISCO, May 16 (Reuters) - Winemaker Robert Mondavi, the man most credited for turning California into a world-class wine producer and millions of Americans into wine lovers, died on Friday at his Napa Valley home at the age of 94.

Mondavi steered California winemakers away from making low-cost wines and toward refined wines, which ultimately would compete in quality with some of the best in Europe.

"He targeted quality before he targeted anything else, and at some point, he merged quality and Napa into a single concept," said Dan Berger, wine industry analyst and publisher of the Vintage Experiences newsletter.

"By doing so, he elevated California wine and Napa wine to a level that most people never would have imagined."

Robert Mondavi Winery spokeswoman Mia Malm said Mondavi's family had told her he died on Friday morning.

Details were not immediately available, but Mondavi had been in ailing health for some time and was confined to a wheelchair.

The son of Italian immigrants, Mondavi first learned about grape-growing from his father. He then traveled the world to expand his winemaking knowledge and went on to create the Robert Mondavi Winery in the Napa Valley north of San Francisco in 1966.
