I finished updating my grape data tool and am again making it available to the public. With this tool, you can quickly and easily pull up historical data going back to 1991 for grape prices, yields, acreage, revenue and derivative data, by variety and pricing district. It includes options for the whole state, total wine, total red, total white, other red, other white and almost every variety. It saves me an enormous amount of time, and I hope it does the same for you. Follow this link to my Excel tools page to download it.
