Nowadays, french organic wines show up consistently among the top ten best wines of any region (when available), being cited in magazines as the most innovative, interesting and personalized products around. Surprisingly, due to a relative lack of public awareness, this quality does not come at a big premium, compared to everything labeled "organic" these days! One theory for this outstanding quality is that organic vineyards have more natural resistance to poor weather or pestilence, and therefore tend to perform better in poor vintages than non-organic ones. Additionally, many organic vineyards hand pick their grapes, rather than using mechanical pickers. This allows only the ripest and healthiest bunches to be picked, with the minimum amount of stress/damage to the vine, fruit or soil.  Organic vineyards choose organic methods to obtain the strongest and richest grapes possible, with the fewest detrimental effects on the environment, and their wines reflect that dedication to quality.
