Managing Winter-Injured Vines
With significant winter injury across the East, growers are faced with vines that have intact, healthy roots trying to push growth up into a canopy without many shoots and a reduced number and size of grape clusters.



  • Cluster thinning in Late Harvest Riesling:  Does it Pay?
    In this Wines and Vines article,  Justine Vanden Heuvel (associate professor at Cornell) and Trent Preszler (former graduate student) present results of a study weighing the costs and benefits of cluster thinning on both production costs (extra labor and lower yields) and 'willingness to pay' for the putative higher quality associated with lower yields.  Cluster thinning lowered grower revenues by $2.4 to $7.6 thousand per hectare, and trained sommeliers from New York City did not express a preference for wines made from cluster-thinned vines.


Dormant Pruning 2014:  Adjusting to anticipated winter injury
Growers in New York used a variety of pruning tactics to leave extra buds to compensate for winter injury.  Here are some photos from before and after budburst.
