Tommy Fenster is a scientist who studies agroecological systems, but specifically for the last few years he’s been focused on gathering data from dozens of vineyards around California and studying the practices and impacts of regenerative viticulture. Tommy gathers data across something like 49 vineyards. In a sense, the largest regenerative viticulture trial is the one being conducted across all vineyards in the world right now as more and more farmers embrace more and more regenerative practices we begin to deepen our understand of how the impacts of regenerative farming compare against the impacts of conventional farming… and Tommy is collecting the data to be able to understand this.  

Grazing is a big part of this conversation, and we get into the weeds about how, when, the impacts in different contexts and season, alternatives to sheep and some of the limitations of sheep, as well as some of the creative ways to incorporate sheep and other animals. There’s some really helpful info here that you might not have considered, as well as some important considerations about the potential issues that can arise. We talk a lot about contract grazing and why you shouldn't make assumptions about contract grazing as an easy way to incorporate animals into your winegrowing… you may need to be more creative.

We also dig into tillage and ask some hard questions about where and when and how and if it is ever a good practice. As California attempts to define regenerative agriculture, I think everyone should learn from the system that Tommy and his team uses to parse what it means across an array of best practices and a variety of contexts.
