Spenker Winery



At Spenker Winery, all our wines are made with estate grown grapes from our Certified Sustainable vineyard.

Since 2006, Spenker Vineyard has been a leading participant in California's 1st third-party accredited sustainable program: Lodi Rules for Sustainable Winegrowing.

Lodi's fertile soils are the epitome of California's prized agricultural land. Making sure that it is used and enjoyed in the most responsible manner is at the heart of the Lodi Rules program. 
Sustainable agriculture practices aim to improve all aspects of farming, from plant to consumer. 

To be Certified Green in the Lodi Rules program extensive management plans must be made, records kept for activities in the vineyard, and decisions made based on best outcomes for the land, the wildlife, the grower, farm labor, neighbors, and the consumer. Environmental, economical, and social responsibility on the farm are crucial to a healthy, stable, and bright future for California.
