Abstract
We present the main outcomes of a comprehensive cost-benefit analysis at the vineyard level of regenerative viticulture in Sonoma County, California. Across four commercial vineyards and a 30-year horizon, regenerative management based on no-till, compost, cover crops, and sheep grazing delivered financial performance close to conventional management when yields were maintained. The results show that the economic success of transition depends mainly on site conditions, planning and operating strategy, and the ability to avoid yield losses or capture added grape value.
