Green vines
We Westerners generally aren’t shy about our Earth-lovingbehavior. We load up on goods from REI to outfit our frequentforays into nature, and we make weekly visits to the farmers’market to buy local produce. One group of us, though, is doing theright thing but not telling anybody ― grape growers andwinemakers.
According to Bob Scowcroft, executive director of the OrganicFarming Research Foundation, more and more California growers areundertaking rigorous organic certification programs. “The big namesare the most visible innovators ― the Gallos, the Fetzers,”Scowcroft says. “They can afford to manage large parts of theirland this way.”
One big barrier to going totally organic is sulfur. A naturallyoccurring element, sulfur is a bit of a savior; it can be appliedto vines to control mildew, and to wines to prevent oxidation andspoilage. But long-term, high doses in the vineyard can lead toexcess soil acidity. Under certain conditions, organic growers mayuse sulfur, but winemakers can’t add it to wines sold as “organic.”The trouble is, wine is a delicate thing; as it comes to life inthe winery, problems can develop, and it can go south. Anall-or-nothing approach to sulfur use can leave a winemaker with noout.
