Before answering this question, it is convenient to underline that in all the regions being under the regulation of a Appellation of Origin Board ( Consejo Regulador de la Denominación de Origen) there are some standards established by this regulatory body which must be fulfilled. The Regulatory Boards of Appellations of Origin was created to establish guidelines or rules to make wines so that the consumer knows that when you buy a wine with a particular Origin Denomination , the wine will enforce those rules to guarantee quality.
For example, in the Ribera del Duero, the Crianza wine must comply among other features, that has been made from grapes belonging to this specific area, further those grapes are authorized varieties, the approved varieties are Tempranillo , Garnacha, Cabernet Sauvignon , Merlot , Malbec , and Albillo that being white grapes can also be used in a small percentage . The aging in the cellar must be at least 24 months of which 12 months must be in barrels less than 300 litters, the production of grapes must be less than 6000 kg per hectare , and also the wine has to pass by a committee of tasting wine certifying that you have enough aroma and flavor quality.
However, there is not a "plus " in case you increase those rules, for instance if you use new barrels, that involves better and positive features for the wine, or whether the production is very low, eg 3000 kg which increases wine quality. I mean, even with improvements to the basic rules, remains a standard Crianza, like other wines using more than 10 years old barrels, or collecting a large production of 6000 kg per hectare . Therefore, many wineries have decided that they do not have to put the stamp of Crianza in their wines due that they overpass these minimum established by the Regulatory Board , and they put a "generic -garnet " stamp, the same that is used for a young wine. That does not mean they are young, but somehow tries to convey to the market that this wine is better than the established minimum rules at the personal opinion of the manufacturer , these wines are those who are called Author Wines, and is the market that should really decide if that wine deserves this name based on its quality.
So the question is, An Author Wine can also be a Crianza ? , The answer is yes, provided that the established minimum criteria are met, then besides being an Author Wine, can also get the stamp of Crianza, with the advantage that much of consumers considers a Crianza as a exponent of quality, while not everyone knows what an Author Wine is, and if you are not putting the official stamp, they may believe that is worse than a Crianza, that is explicitly written in the label of the wine. In fact, there are many wines which intend to pass by an author wine and do not meet the minimum requirements needed for a Crianza, so in some way the market is right when they ask for a Crianza having the official stamp.
In our case, Camino Soria wine is aged for 14 months in new barrels, with a production of less than 3000 kg per hectare , well developed with quality criteria that exceed the usual methods of any cellar for a typical Crianza wine, then I like to call it Author Wine, because he really is, although I have not wanted to renounce to put the Crianza stamp in my wine too, since it meets and overpass all the requirements, so I also want to keep that sign of quality that gives the Crianza for a major part of market. I hope I have given some light about the meaning of this term of Author Wine.
