This can effectively promote the development of the grape industry. Compared to simply growing grains, the income from growing grapes is significantly higher.
But the bad news is that in the north of Spain, there is a country more famous for its grape industry, which is France.
French wine is truly the bestseller in Europe, even causing a scramble among the majority of European nobility.
Of course, this has certain historical reasons. During France's most prosperous period, the language used in diplomacy by European nobles was French.
When nobles provided elite aristocratic education to their children, besides learning their own country's language, the first foreign language they learned was French.
With the spread of French, French wine also became popular throughout Europe. Although France has been in continuous decline, the nobility of various countries has not lessened their affection for French wine.
