This isn't exactly about effective winery Web sites, but the story behind SidewaysWineClub.com will be of interest to those of you who sell wine online. A sample quote:
...the wine industry is unique for its brand proliferation. There are over 3,500 domestic wineries, each producing 1-36 labels after each harvest, resulting in well over 17,000 domestic wines available for sale at any one time. Of these choices, the 100 best-selling labels account for over 90% of volume.
It provides a good summary of the problems with selling wine online, e.g. the risk of the unknown, and has some ideas for marketing an "experience-based" product like wine.
It's not clear from the article how SidewaysWineClub.com is doing financially, though. Having done licensed software products, the cost of licensing a name (in this case, Sideways) can make the economics less favorable.
Thanks to MarketingProfs.com free newsletter (which I recommend) for the pointer.
