There are a couple of very interesting Garnacha Tinta crosses. One is the Marselan that comes from the crossing of Grenache and Cabernet Sauvignon and another is the less-known CALADOC, which comes from Grenache and Malbec or Côt. Below we carry out an in-depth analysis of the variety.
1- The Caladoc grape. Introduction:
Caladoc was created at INRA in Montpellier by Paul Truel in 1958. It is a cross between Garnacha and Malbec (Côt).
It is registered in the official catalog of vine varieties in France and authorized and even recommended in most French regions.
It is used for PGI wines (Protected Geographical Identification) but at the moment it is not authorized for AOC wines (equivalent to DO in Spain).
It is also listed in the catalogs of Bulgaria and Portugal and is also cultivated in Poland, Lebanon and South America.
Main French production regions:
The main producer regions in Francia are: South-West, Bordeaux, Languedoc-Roussillon, Provence-Corse, Loire, Beaujolais, Savoie-Bugey, Cognac.
The caladoc in Spain
In Spain , its use is not very widespread, but it is a strain with potential for our country.
It adapts well to areas where Grenache Tinta and Malbec work well, since these are its progenitors.
2- Synonymy, different ways of knowing the same grape variety
Caladoc is also known in France under the name INRA 1510-104 and Caladok in Bulgaria.
3- Clones of the caladoc
There is only one selected clone of this variety, the 724.
