Summer in Sonoma

Sonoma and Napa Counties are a wonderful place to spend the summer. The weather is usually in the mid 80’s during the afternoon, but fog gently covers the landscape most mornings and some evenings.  This is especially the case in Carneros and Sonoma Coast appellations, which are closer to the Pacific Ocean and San Pablo Bay.  This cooling marine influence is what allows us to grow world-class pinot noir and chardonnay in these areas.  However, if the fog is too cool for some (as it was for Mark Twain when he spent a summer in even cooler San Francisco), you only need to drive a few miles inland to find the hotter areas of Alexander, Dry Creek, and Calistoga where cabernet sauvignon and zinfandel thrive.

This summer on campus we are offering classes in both the June and July sessions.  Many students can accelerate their studies by taking for-credit classes during this time.
I am not teaching this summer, because I am working on research and a new book.  In addition, I have much travel planned, including trips to France, Italy, Croatia, Wisconsin and Arizona.

During the summer I also work much in my vineyard.  We got off to
a cool start with unseasonably cold and wet weather at the end of May and first
of June.  This caused delays in fruit set and increased threats of powdery mildew.
I have had to spray the vineyard with sulfur and Serenade (both organic products) more than usual.  Everyone is predicting a delayed harvest again in this area. Interestingly France is experiencing a drought with no rain in April and May including heat in the 90’s.  Their vines are much more advanced than ours at this time, and they are predicting
one of the earliest harvests on record – perhaps in August!  It is amazing how much control Mother Nature wields, and so for the summer months, I offer a few quotes in honor of her power.

“We cannot command Nature except by
obeying her.” – Francis Bacon

“Let us permit Nature to
take her own way; she better understands her own affairs than we.” – Michel de
Montaigne
