Updated: April 8, 2021 4:01 a.m. In the summer of 2019, Rose Fumoso left her home in southern France to intern at a Sonoma County winery, where the 21-year-old greeted customers in the tasting room and assessed the ripeness of grapes from the vineyard. As the season wound down in September, a friend invited Fumoso to a party celebrating the end of harvest. There, she met the host: Dominic Foppoli, the mayor of Windsor. A small town in the heart of Wine Country, Windsor has transformed in recent years from a sleepy neighbor of Healdsburg to a tourist destination. Much of that rise has been credited to Foppoli, a young winery owner whose political star and push for development have attracted outside investments in the community.
