An innovative irrigation system that showed promising yields and fruit quality despite drastic cuts in water use during the 2015 drought didn’t replicate its results in the second year. That’s not bad news, according to lead researcher pete jacoby, who explained that the goal of the experiment was to test the limits of the vineyard.
