I went to a fair and saw a book "Wineries by County". It is going to be on the market in a few weeks. The author was there with a copy to display.
It is a really nice colorful informational book on California wineries and vineyards. There was no advertisements and just full of information. The book has over 1000 California wineries and vineyards with maps too. I recommend this book to anyone that likes to order wine or visit for picnics and wine tasting.
The authors web site is www.wineriesbycounty.com take a look at the site. Wow about time all the wineries are in one book! I have several books that don't even cover but one county. This book has them all in one.
I am going to buy several for birthday gifts and one for myself.
