Canopy management is now an active area of research, especially
in the New World wine growing countries. It is generally
accepted that Dr Nelson Shaulis of New York State
pioneered canopy studies, especially with publication of the
Geneva Double Curtain trellis (Shaulis et al., 1966). However,
many of the principles that have emerged from recent
research on canopy management are consistent with empirical
observations and practices long since employed in Old
World vineyards
