Social networks are going mainstream on the wave of the advance of MySpace and Facebook. We can divide them into two groups:
- General social networks: they are social networks like Facebook, in which users can talk about whatever they want (music, food, wine, personal opinion on brands, …), can share information, pictures, songs, posts, articles, … And, overall, users can build a personal network of relations.
- Niche social networks: they are social networks on a single topic of common interest. There are several examples of this kind of social networks, for instance ASmallWorld, … Also the wine world has them and we can call them wine social networks (WSN), in which the common interest is wine in all its aspects: reviews, recommendations, tasting notes, personal information, networking, sharing of knowledge, …
I have found 15 wine social networks, probabily the most important in terms of use by thousands of internet users and wine lovers. I think, also, that a winery should check its presence inside a WSN, if some users has posted a review and so on. Even be part of a WSN should be an interesting hypothesis for a winery.

Calwineries

Calwineries’ mission is to address this: making California’s wine country accessible to everyone. (Philosophy) Wine cannot be explained by one person.

WineLog

WineLog keeps a record of wines that you have tried: When you venture to try a new type or variety of wine, you are taking the risk that you will either love it or hate it. WineLog provides you with a free way to track your preferences on new wines, including the specific information about the wine, as well as personal and public comments and one to five-star rating. After trying a new wine, simply login and select “Add wine to log.” You will fill out a simple form about the wine and then it will be added to your log. With this feature, you can remember which wines you enjoyed and purchase them again, and you can also remember which wines to avoid in the future.
WineLog proposes custom wine recommendations: Most people base their wine decisions on magazine reviews and ratings. The problem with this approach is that general reviews and ratings do not take your wine preferences into account. Using our wine recommendation system, we are able to compare your recorded comments and ratings to those of other WineLog users. If you and another WineLog user both highly rate one brand of chardonnay, then it is likely that you and that user both enjoy similar qualities of chardonnay. Your WineLog displays the other chardonnays highly rated by that user and proposes them as wines you may also enjoy. The more wines you enter into your log, the more specific you wine recommendations will be. More info here
