Higher concentrations of anthocyanins and skin tannins in berries , coupled with a lower concentration of seed tannins were associated with higher wine quality .The ratio anthocyanins , skin tannins/seed tannins is proposed as an indicator of flavonoid composition,wine colour and wine quality . Excessive canopy shade was detrimental to berry and wine composition and intensified sensory detection of ‘straw’ and ‘herbaceous’ characters in the wines.
