Sustainability

We’re all in this together. Our mission at Corison Winery is to produce world-class Cabernet Sauvignon with integrity.
With this intention, one of our founding principles is to minimize negative impacts on the environment.

Kronos and Sunbasket Vineyards are certified organic by CCOF. Compost and cover crops promote flourishing soils which, in turn, nourish the vines. Sheep graze down the cover crop in early spring, and their nutrient-rich droppings also feed the vines and the microbial life in the soil. We till to manage weeds with our electric tractor.

Nesting boxes abound in the vineyards to encourage obliging birds to take up residence. Bluebirds consume harmful insects, including leafhoppers and mealybugs, and Barn Owls hunt four-legged varmints. We do not use any synthetic pesticides or herbicides. 

With water being one of our biggest challenges in California, we are nudging our vineyards toward dry farming, encouraging our mature vines to send roots deep into the soil. Kronos Vineyard grows on deeply-rooted St. George rootstock, which is known for its ability to be dry-farmed. State-of-the-art water stress sensors and drip-irrigation help us optimize this precious resource when the vines do need water.

Mindful of our carbon footprint, solar panels on the winery roof produce all of our electricity.  Cathy commutes to the winery and makes her vineyard rounds gasoline- and emissions-free by bicycle or electric car, and the winery offers charging stations for visitors. We use an electric forklift in the winery.

William built passive night-cooling into the design of the winery with the cool night air drawn in through louvers on the ground floor and warm air vented to the outside through classic cupolas on the roof. And behind the scenes, our goal of paperless administration is within sight.
