The Citrus Belt

A narrow corridor of the Inland Empire forms the historic heart of California's citrus industry. It stretches from Riverside through Redlands. This is the Citrus Belt: a microclimate so well suited to growing oranges that early settlers called it "the land of perpetual sunshine."

The magic is in the extremes. Hot, dry summers push sugar deep into the fruit. Cool nights develop the complex acid profile that gives California juice its balance; temperatures regularly drop 30°F after sunset. And the low humidity means the fungal diseases that have devastated Florida and Brazil simply don't take hold here.

Geography plays a role too. The San Bernardino Mountains block cold desert air from the north. The Santa Ana winds channel warm, dry air through the valleys. The result is a frost-free growing zone sheltered by natural terrain. A greenhouse without walls.
