Surround Crop Protectant Trial with Petit Verdot (2014)

Petit Verdot that received heavy leaf pulling was either sprayed or not sprayed with Surround Crop Protectant in the fruiting zone in order to prevent sunburn.  No chemical, phenolic, or sensory differences were found in this study, suggesting that Surround does not negatively impact finished wine quality.  However, this year was a relatively light "sunburn" year at this vineyard, so the true impact of Surround may not have been adequately quantified.

Leaf Pulling Trial with Petit Verdot (2014)

For one half of a single block of Petit Verdot, leaf pulling was done on the east side of the vines. For the other half of the block, leaf pulling was done on both the east and west sides. The leaf pulling was done approximately one month prior to harvest. There were very little chemical differences between the wines, and no significant sensory differences were found.
