CUBA: An internet-based software application for berry anthocyanins units’ conversion for viticulturists, oenologists and physiologists

In viticulture and especially for red wine production it is important to know the grape quality. Anthocyanins, the red pigments of berry skins that define the colour of wines, are good indicators of the so-called phenolic maturity of grapes. We provided an easily accessible mean to convert anthocyanins units acquired by different analytical methods. It is available as a free internet-based tool accessible from all supports, computers, tablets and smartphones. The usefulness of this software tool was illustrated by simulation of the influence of berry mass and skin mass per area on the anthocyanin content of the must.
