For more than 20 years we began with the study of our Canarian varieties, we have not stopped taking daily steps in the search for the necessary knowledge that would help us understand them in order to obtain the maximum expression of them.

Throughout all these years, as work has progressed, in Viñátigo we have been able to put on the market, for the enjoyment of wine lovers, numerous varieties: Gual, Marjamuelo, Vijariego Blanco, Malvasía, Negramoll, Vijarieigo Negro, Tintilla, Baboso Negro.

We started initially, back in 2002, with a project developed with the support of the Galicia Oenological Station EVEGA, through which we face the morphological description of many of our varieties, fertility studies and oenological aptitudes.

Later, together with the University of La Laguna, we deepen the study of two of the most interesting varieties we have studied. the Gual and the Marmajuelo, comparing them with the most widespread, the White List.

Throughout all these years, we have continued conducting numerous studies, with the participation of various Institutions and Organizations such as the University of Zaragoza through its Aroma Laboratory, deepening among other aspects in the knowledge of the aromatic descriptors of each of The varieties.

As we advanced in the knowledge of the oenological potential of white varieties, we also did it with red varieties, first through a study at the University of La Laguna and then with deeper work at the Rovira and Virgili University. As a continuation of these last works, and also as a result of the friendship with Fernando Zamora, we began the necessary process of molecular identification of the varieties, with the very important contribution of Dr. Francesca Fort. In this initiative we managed to involve several DOs and wineries, who with their technicians collaborated in the field work, as well as Paulo Rodrigues, who at that time was president of the Madeira Wine and Embroidery Institute, IVBAM, which allowed us collect samples in that region, which for historical reasons we were very interested in understanding the origin of our viticulture.

As a result of the last years of efforts, a first article has just been published, Molecular characterization of Vitis vinifera L. local cultivars from volcanic areas (Canary Islands and Madeira) using SSR markers, whose authors are Gemma Marsal, Juan Jesús Méndez, Josep Maria Mateo, Sergi Ferrer, Juan Miguel Canals, Fernando Zamora, Francesca Fort. Vol 53 No 4 (2019): OENO one

As a summary, this publication expands the scientific knowledge of the wine heritage of the Canary Islands, obtaining as the most relevant result the confirmation of 14 varieties and 3 mutations as exclusive to the Canary Islands.

In addition, the article confirms the identification of 4 new varieties and 2 color mutations described for the first time, as well as shedding light on the possible origin of many varieties derived from the statistical analysis of the results of genetic studies, and finally, clarifies the use of many synonyms.
