This year, as you well know, has not been kind weather-wise — not to grapevines or humans.  Dr. Damon Smith has a vineyard at the Cimarron Valley Research Station at Perkins where he conducts research on Black Rot.  The vines are now in their 3rd leaf — at least those that survived the winter.  We took some photos of the state of the vines to show what kind of things we are dealing with this year.

In the vineyard most of the severe damage was done to the vinifera grapes — Petit Manseng, Gruner Veltliner, and Lemberger.  So much so that they will be taken out this winter and replaced with other varieties.  The hybrids performed better, but some with a high amount of vinifera had a few vines die.  No variety was entirely spared of some kind of injury, but the cold hardy Frontenac gris did well for the most part as did Cynthiana and Rubaiyat.
