Field trials: When nature lets you down

This was an experiment I conducted in 2011. I wanted to see what happened to Pinot Noir if  we restricted precipitation ingress through the period veraison  -3 weeks. We could detach the covers, and allow some rainfall to hit the ground, but it didn't rain.

We lifted the covers after veraison, and still it didn't rain.

No rain until harvest, in fact.
