Does water deficit negatively impact wine grape yield over the long term?

Abstract

Like many other woody perennial crops, grapevine reproductive development occurs over a two-year cycle. Given that water deficits are commonplace in viticulture, especially for red wine grape production, this raises questions about how water deficit in the current season could potentially impact yields the following year. This article will focus on the long-term effects of water deficits on grapevine yield.
