Top Varietals
Before the new search engine it wasn’t possible to search wines by varietal even though that information was always available. Now not only you can search by varietal but we’ve also added a nice list of the top varietals on Adegga.

Latest notes
We’ve also decided to display a list of latest reviews made on wines (instead of always showing the top wines by winerank) to show how alive the community is.

A while ago we developed something called the Winerank that is basically a ranking to describe how interesting a wine might be. The ranking is called social because it is based on the actions that each of the members of Adegga do for each wine. Lets see in detail how the process works.

The algorithm is a bit complex but it basically takes into account a bunch of properties for each wine and combines them together in a final value. Here’s how it works, for example, for the Cortes de cima Reserva 2003:

We know that:
- 18 people have tasted the wine
- 12 people have marked it as a favourite
- 17 people own at least one bottle
- 17 people wish this wine

We first weight these numbers based on other wines and then add them to the formula. We also add a couple more weighted values for the remaining wine properties (average rating, number of notes, etc.). In the end we get a final value that determines the Winerank of the wine.

The Winerank is automatically calculated every day for all the wines in the database so it can take up to 24 hours for your actions to influence the final Winerank of wine and the order of the lists that you see when you browse wines on adegga.

Wines lists are usually ordered using ratings. On a community like adegga this has two problems: 1) it assumes everyone is rating wines and 2) is assumes that ratings scales are all used equally. Neither of this points are true and so we decided to create a new way to rank wines based on their social activity.

The Winerank is basically a new way to measure the level of interestingness of a wine and it is based on the actions taken by the community members on each wine.

The winerank for each wine is calculated using an algorithm that includes many wine properties: we included the wine’s average rating, the number of written wine notes, the number of times the wine was selected as a favourite, how many people added the wine to their wishlist, the number of people who have the wine in their cellars and a few more properties. On top of these we add weights to each property in order to bring out the best results.

The Winerank evolves with the community as more people add their ratings, favourites, wishes, etc. The overall ranking is re-calculated every 24 hours. Check the current top Wines by Winerank to see the rank in action.

We hope you enjoy this new social way of discovering wines.
