Heat Wave and Our Cabernet Sauvignon

The summer of 2020 has been one of a series of heat waves. According to our local news, we have had 30 days of above 90^o F temperatures. Even the weeds in our vineyard are dying and the grass under foot is crunchy.
What does this do to grapes? In July, I blogged about Leaf Pulling in the Cabernet Sauvignon, exposing both sides of our canopy. We began leaf pulling around 10 days after fruitset, but during the time when temperatures were in the 90s.
This is the result:

Fortunately, not all of our Cabernet Sauvignon look like raisins. A good deal of the grapes survived our well intentioned but ill timed leaf pulling and look like this:

My husband informed me that what we were supposed to do was to leaf pull from the east side before veraison and then leaf pull the west side of the canopy after veraison. Lesson learned!
