Here are some tidbits I wrote on my blog about G. Conterno Cerretta Barbera (and Nebbiolo) after visiting the winery a couple of times and trying wines from botte and also from bottle.
The 2010 vintage continues to be my favorite for Cerretta, in both Barbera and Nebbiolo. In fact, the 2010s are extremely strong at G. Conterno across the board, and they may well prove to be some of the finest wines produced from the region in that excellent and impressive year. Interestingly, this 2010 Barbera from Cerretta was at the same alcohol level as the 2009 Cerretta Barbera, which is something I wouldn't have expected.
There was a side by side of the Barberas from 2011. Roberto feels that the 2011 Cerretta Barbera has some similarities to the 2009 Cerretta Barbera. The Cascina Francia, in my own estimation, had a more mineral tinged aspect than either.
Interestingly, although the 2009 Cerretta Nebbiolo had already been bottled, the 2009 Cascina Francia Nebbiolo has not been. The 2009 Cascina Francia Nebbiolo, if I understood correctly, will be in wood for a year longer than the Cerretta Nebbiolo 2009 was. Roberto said that he did not want to dry out the fruit of the Cerretta with more time in wood.
Roberto told us a bit about the differences between Cerretta and Cascina Francia. He said that Cerretta gives more fruit and tannins, while Cascina Francia shows more minerality. He said that for Cascina Francia he prefers the 2008 vintage (which I tried during our visit and really liked) to the 2009 vintage, as the 2008 vintage is more complete of a wine and he in fact adores it, but that for Cerretta he preferred 2009. He also talked a bit about his decision making regarding whether his Nebbiolo from Cerretta should be labelled as Barolo, as it well could be. Up to now he has declined to do this, because he has been hesitant to say that the wine is at the level of a Giacomo Conterno Barolo, but for the 2010 vintage he will probably do so. Roberto said that in his opinion the 2011 vintage would be the real test of Cerretta in terms of its suitability for the "Barolo" label, because it was a difficult vintage in general.
