Central Valley

In california, this great expanse is divided into the sacramento valley in the north, which produces small quantities of wine, and the vast san joaquin valley in the south, which supplies the majority of the state’s bulk wine (and table grapes and raisins). Plumbed by an extensive system of rivers out of the Sierra Nevada and irrigation canals built since the 1920s, this large, fertile, sunny region is arguably the most productive farmland in the world with more agricultural output than the whole of China until 1990.
