We want it to be seen that an incorrect calculation can come to give a correct product, they explain from Bodegas Alcardet, which add that we understand that unexpected things can happen. Thus, they explain that the grape with which they then make their product is exposed to a different climate, to a changing environment - and hence the idea of reflecting that calculation whose sum does not give the final result, but that once it is taken there is what was wanted.

From the manufacturer of the wine:

Correctness is not always an exact operation, just ask Alexander Fleming, the father of penicillin, or Marie Curie, the creator of radioactivity, whose fortuitous discoveries were made possible by unforeseen factors.

Today, oenology is a mixture of tradition with experimentation and technological innovation. At Bodegas Alcardet we consider Correcto a wine far from all calculations. Its success lies in the winemaker's freedom to combine the benefits of success and failure.

We flee from the precision that sometimes oppresses us and focus on the subjectivity of the unexpected. The essence is not always found in perfection but in the error that changes everything and makes it unique and special.

The Wonderful Mistake

As for the number significance, who knows? They never explained the specifics from what I could find.
