No less an authority than Gaiter & Brecher (the wine columnists for The Wall Street Journal) points out why having an effective Web site might just be very important to a winery:
So here's our advice: Go online and, if it's possible where you live, get some wine from a smaller winery that you've never heard of -- and do it before it's discovered. Just search for "wineries of Virginia" or "wineries of New Mexico," find one that sounds interesting and see if you can order a mixed case.
This quote is take from their June 17th column, Wines That Really Know Their Place (subscription required), and it underscores why we think it's so important for your Web site to explain how to buy your wines (and even whether it's possible). If the Wall Street Journal encourages people to go online to find wine, your site had better be up to the task. You need a site that makes it easy for visitors to accomplish what they came to do (whether it's buying your wine or finding out if they can drop by the winery).
By the way, if you looking for wineries that you've never heard of, our comprehensive A-Z list of wineries is a great place to start. The three smaller wineries mentioned in the column (Churon and Cilurzo in Temecula, Hart in Napa) are all on our list.
