Lockewood Vineyards
Steep in History | Farmed for the Future
Background & History
Lockewood Vineyards started with one family’s four generations of winegrape growing tradition. The vines benefit from the sandy loam, Delta breezes, the hot summer days, and sustainable farming practices.
Our vineyard was previously owned by Rudy Maggio (2022 inductee into the Ag Hall of Fame, San Joaquin County) and owner of Oak Ridge Winery. Rudy’s family came to Lodi in 1928. Rudy Maggio, born in 1940, started farming at the age of 12 when his father, Roy was paralyzed by polio. By the time Maggio was 20, Roy Maggio & Son was formed. They farmed Tokay grapes on family land west of Lodi, leased acreage, and performed custom farm work.
Maggio bought his own piece of land totaling 40 acres in 1963 and built the family home on it in 1966.
According to records, the Zinfandel vineyard was planted in 1963. It was interplanted with additional Zinfandel around 1991 and converted to wire. The home and vineyards were later sold to one of Rudy’s daughters and her husband.
The Merlot vineyard was planted by Rob and Lisa Kammerer (Rudy's son-in-law and daughter) in 2017.
The current owners, Leonard and Alyce Peterson acquired the historic vineyard in 2021. They named the Lockewood Vineyards because the vineyards wrapped around the home and created a sense of warmth and security.
The vineyard is certified sustainably farmed by Lodi Rules.
