Frog's Leap Winery is a California wine producer that operates from Rutherford. It was founded in 1981 on a spot along Mills Creek known as Frog Farm. Frog's Leap Winery was established by John Williams and Larry Turley.
In addition to their accolades for their wines, Frog's Leap is also noted for its humorous approach to winemaking, down to their "Ribbit" corks. The winery got its name by combining "Frog Farm" (where its first wines were made) with "Stag's Leap" (where John Williams had his first winemaking job).
