Rancho de Philo Winery

Rancho de Philo makes one wine. Since 1974 it has produced a Triple Cream Sherry from Mission grapes — the variety Spanish missionaries planted when California winemaking began — aged through a traditional Spanish solera, the stacked-barrel system in which younger wine is blended patiently into older. Every bottle carries wine from decades back. Nobody does this anymore; that's the point.

The catch is also the charm: in-person sales happen in November only. One month a year, the Alta Loma winery opens for its release, and buyers plan around it like a harvest festival, because that's effectively what it is.

Alongside Galleano down in Mira Loma, this is a living remnant of the Cucamonga Valley's wine era, when this region grew more grapes than Napa. A cult bottle made a few blocks above Foothill traffic, on Wilson Avenue, by a family that never chased scale. Call first — (909) 987-4208 — and put November on the calendar.
