The winery reviving the historic Regina Winery property on Base Line — tastings, classes and restored vines.
d'Ellena occupies the historic Regina Winery property on Base Line Road — the landmark winery grounds long associated with the Filippi family, whose Rancho Cucamonga operation closed in 2025. A new name on that property is genuinely significant local news.
The stated project is restoration: the vineyards, the architecture, and a working tasting room with classes and events, rather than a museum. For the Cucamonga Valley story this is the counterweight to everything that has closed — an operating winery on one of the valley's most storied sites.
It is at the east end of the city near Day Creek, a long way from the industrial tasting rooms further south, and the setting is the point.
