Polyphenols in Hellenic wines: creating composition tables as a tool for epidemiological studies
Polyphenolic substances are of profound significance to both the technological and nutritional value of grapes (Vitis vinifera sp.) and wines. The Hellenic vineyard embraces a large number of native V. vinifera species which have a peculiar polyphenolic composition, as illustrated by a number of recent research works. For this reason it was deemed necessary to gather the bibliographical data that have been published so far, in order to provide a complete insight into the polyphenolic composition of Hellenic wines, with a view to it being a first step towards the creation of a database which might be of assistance in epidemiological research. Emphasis has also been given to some data that revealed valuable information on variety-related patterns for major phenolics in wines made from single, autochthonous cultivars.
