During the XVIII century an important progress started in Spanish Oenology with the cultivation of new kinds of stocks coming from France, Italy and other countries, that were planted in cuttings or grafts. To be successfull the best lands were chosen and new vinification techniques were experimented, introduced by Winery masters under contract from the neighbour France or Italy, with the final prurpose of increasing the quality of our wines.
With these innovations, during the XVIII century Spanish wines began to be divided into two different groups:

• Those wines obtained still from the very old kinds of stocks existing in our country since ages. Ordinary wines, sometimes of very good quality, but almost of domestic production, and whose quality varied a lot from harvest to harvest.
• In a second group we would find a group of wines that were developping with the time until being the most important one. It was formed by the wines proceding from imported stocks or experimental grafts,cultivated rationally which were richer in quelity but not in quantity. All of them were elaborated in Wine Cellars with industrial purposes and in conditions that tried to obtain a better aging.

In the Royal Court, during this century, the ones next to the city were mainly consumed such as the wines from Valdemoro, Arganda, Navalcarnero or San Martin de Valdeiglesias. The wines from Toledo or from Ciudad Real, specially Valdepeñas, started to come in with a big impulse.
