At Bouchaine Vineyards, nestled in the Carneros region of Napa County, where the land opens up toward San Francisco Bay, animals are partners in sustainability. Flocks of sheep graze on the weeds under the vines, and a falcon beats its wings as it staves off flocks of birds. Their efforts do double-duty: keeping away invasives and pests, while attracting wine country visitors eager for a unique experience. Watch here, from ABC-7, Chicago.
