Summary Statement

Is a simulation model of grapevine growth and development. Vine Logic is an education and strategic decision making tool enabling "what if" scenarios to be explored for a wide range of vineyard configurations. Education package will be available in 2002. Version two will be available in 2003. Model may be useful for predicting future hydrological conditions where grape growing is expected to expand.
