History of French wine

French wine originated in the 6th century BC, with the colonization of Southern Gaul by Greek settlers. Viticulture soon flourished with the founding of the Greek colony of Marseille.The Roman Empire licensed regions in the south to produce wines. St. Martin of Tours (316-397) was actively engaged in both spreading Christianity and planting vineyards. During the Middle Ages, monks maintained vineyards and, more importantly, conserved wine-making knowledge and skills during that often turbulent period. Monasteries had the resources, security, and motivation to produce a steady supply of wine both for celebrating mass and generating income.During this time, the best vineyards were owned by the monasteries and their wine was considered to be superior.Over time the nobility developed extensive vineyards. However, the French Revolution led to the confiscation of many of the vineyards owned by the Church and others.
The advance of the French wine industry stopped abruptly as first Mildew and then Phylloxera spread throughout the country, indeed across all of Europe, leaving vineyards desolate. Then came an economic downturn in Europe followed by two world wars, and the French wine industry didn't fully recover for decades. Meanwhile competition had arrived and threatened the treasured French "brands" such as Champagne and Bordeaux. This resulted in the establishment in 1935 of the Appellation d'Origine Contrôlée to protect French interests. Large investments, the economic upturn following World War 2 and a new generation of Vignerons yielded results in the 1970s and the following decades, creating the modern French wines we know today.
