I can't believe how FRUGAL this was. We checked out a local winery, Indian Island Winery. It was only $5 for seven tastes and you got to keep the glass. You can't beat that!
Here is a site that has a winery locator by state. I don't think it's complete, because I know of a couple near me that are not on the list. Still it's a start. http://www.allamericanwineries.com/AAWMain/locate.htm
Do you have any wineries in your area?
