San Francisco Bay

Oenophile Oz Clarke takes novice James May around California's wineries. They visit a vinery in Oakley that is more than a century old, and Fred Kline, the owner, explains that he is constantly fighting the urge to sell his prime real estate, which is surrounded by urban sprawl.

Oz concentrates on wine, visiting a vinery that makes their favourite variety, Zinfandel. James, however, slips in some go-karting and a trip across the Golden Gate bridge in a vintage Mini.
