John Dawson puts out a very interesting/freebie newsletter/tasting notes that focuses on the people and wine of SonomaCounty. It is very well-done and can be had upon e-mail request from: sonomawinejournal@gmail.com
I highly recommend it...it's a very interesting read.
This 2'nd edition has an excellent feature of Fred Scherrer, one of my favorite winemakers whom I've yet to meet. Also covered are Arnot-Roberts, Shane Finely (asst winemaker at Kosta-Brown) and KenFreeman. Plus an assortment of recent releases from across SonomaCounty.
