California can be called the motherland of viticulture in the USA. It is also quite rightly called "Wine State", because wine is an important economic factor here. In the 16th century, the Spaniards introduced the Spanish variety Listán Prieto to Mexico, which was called Misión here and later Mission in California. In 1769, the Franciscan friar Junipero Serra (1713-1784) supposedly planted the first vineyard with this vine when he founded the Mission "San Diego" in California (according to more recent sources, not until ten years later). Here, there were not the big difficulties as on the east coast of the Atlantic, because the dry climate prevented fungal diseases and the vines thrived splendidly.
