I mentioned in a previous post that among the best ways to learn about wine is at the wineries themselves.  Naturally there are some potential barriers to maximizing your knowledge in this fashion – chief among them is access to a variety of wineries that might fit your needs.   Getting to most wineries usually involves a planned trip, with planned times and locations.  So unless you plan to spend a week or so in a particular area you have to be rather surgical with your plans.
