California can be called the motherland of viticulture in the USA. It also quite rightly bears the beautiful epithet "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) allegedly planted the first vineyard with this vine when he founded the "San Diego" mission in California (according to more recent sources, not until ten years later). Here there were not the great difficulties as on the east coast of the Atlantic, because the dry climate prevented fungal diseases and the vines thrived splendidly.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
