With the strong belief that the best wines come from the best fruit, we have begun making a series of major investments in all of our vineyards (HMR, Anna’s, Viking, Michael’s and our newly planted vineyard.) Our two key goals are that every bottle of Adelaida wine represents our vineyards and that our farming practices ensure the long-term vitality of the vineyards.
For starters, we are doing away with herbicides. While convenient, cheap, and certainly effective in the short term, herbicides are unnecessary at best and at worst they disturb the natural habitat of beneficial insects, among other things. To combat weeds, we have purchased a cultivator that cuts weeds in the vine rows without harming the plants.
Next, we are looking to build up the soil health by choosing cover crops that match each ranch and each soil type within each ranch. The cover crops will provide nutrients, erosion resistance, and a home for beneficial insects. As part of this program we will introduce organic compost into the vineyard in the winter.
We are taking a closer look at vine nutrition. As the saying goes--and with some caveats--struggling vines make great wine. This adage has its limits, of course. We don’t want to kill the vines, but we also don’t want them fat and happy. So, we will be measuring the vines’ uptake of nutrients at critical points during the growing season—bloom and veraison—to determine whether they require supplemental micronutrients. And we will also be measuring how much water the vines are seeing by using a pressure bomb.
In the spring of 2013 we planted 23 acres of new vines comprising Zinfandel, Alicante Bouchet, Grenache and Carignan. They are on a steep hillside facing south. We will head-train these plants—that is, they will grow up without a trellis-- and we will farm this area without irrigation.
Finally, we have retained Daniel Fischl of Eartrumpet Consulting to help guide us to reach our goals. Daniel is an experienced viticulturist with clients in Australia, China, Italy, Israel and Napa. His current and former clients include Screaming Eagle, Harlan, Bond, Aubert, Peter Michael, and David Abreu.
