Growers in the Loire Valley, France are some of the most eco-friendly on earth. They produce their wines in the traditional manner of their ancestors.
Traditionally, French vineyards are not irrigated. (However, they are experimenting with irrigation in the warmer parts of France due to the climate change). The vines normally would have to rely on natural rain water. As a result, the roots of the vines grow far down into the earth as they get older – sometimes more than 20 metres deep.
