I have a friend with whom I have dinner every now and then and where, each time, one of us introduces a new wine to the other. This time it was my friend's turn. While I have a clear preference for the Douro region (north of Portugal), he has a clear preference for Alentejo (south of Portugal). This time he brought a wine called S de Soberanas. And this time, the wine was not from Alentejo. Instead it was from Terras do Sado. Terras do Sado is a name of a wine region that includes a southwest region in Portugal around the Setubal peninsula. However, though this wine reflects this Sado Terroir, it is a wine that is made of typical grapes from Alentejo. And perhaps that's what makes it so amazing.
I actually enjoy some wines from this region quite a lot, like the classical Periquita and Quinta da Bacalhôa, but you don't usually expect a wine of this level from this region. It is a very rich wine combining the freshness of Sado with the typical flavors of Alentejo. This one is only produced in exceptional years, as it was the case of 2004 (the one we drank).
You can read some tasting notes (in portuguese) here.
It is an expensive wine but with a great quality/price ratio. Enjoy!
