Elemental composition, rare earths and minority elements in organic and conventional wines from volcanic areas: The Canary Islands (Spain).

The organic wine market is rapidly growing worldwide, both in terms of production and consumption. However, the scientific literature is not conclusive regarding differences in the elemental composition of wines according to their production method, including both major and trace elements. Minerals...
