Rolland is a popular subject when talking about 'international' wine... whatever that is.... (??)
There are plenty of folks that love what Rolland does, and a good number that hate what he (and other flying wine-makers) bring to market. Im on neither side of this fence....
I think that you have to look into the details.... and decide on a case by case basis. As an example, while I do conceed that Clos de los Siete is a well made wine, I think that it lacks uniqueness and pales in comparison to other Rolland and Rolland related products.
What do I like thats made by Rolland..... Yacochuya, now there is a unique wine that has a true identity... ^ Bodega Benegas is one of the few 3rd party consulting gigs that Rolland still maintains in Argentina... and this board knows of my love of the wine made by Federico Benegas Lynch (with advice from Rolland). Other producers making very good stuff not always known outside of Argentina include Ricominciare, Escorihuela, Durigutti, Universo Austral, Chacra, Manuel Lopez Lopez... just to name a few...
Regardless of liking Rolland and his colleagues or not, I still do recognize their efforts that have done a lot to put Argentina on the map of the international wine world. For this, perhaps Rolland is top of his class.... I think he deserves to be bestowed with
La Orden del Libertador General San Martin, one of the highest honors that are given out by the Argentine Republic.
