Frog's Leap Winery is located in Rutherford, at the very center of the Napa Valley. Owned by John Williams, Frog Leap was founded in 1981. 

Frog's leap was originally started on a historic property known to be a commercial frog farm in the late 1800s. When John Williams first came to the Napa Valley in 1975, he began making wine for a little-known winery called "Stag's Leap Wine Cellars". In 1976, John and his friend Larry Turley made their first barrel of wine at the "Frog Farm: with "borrowed" grapes from Stag's Leap, and coined the name "Frog's Leap" as an inside joke. In 1981, John and Larry decided to get serious and the rest, as they say, is history.
