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