The varieties used for the production of red or rosé wines are generally referred to as "red varieties", although the berries must be blue to black in colour because only these have the necessary dark anthocyanins (colouring agents). Berries with red and also dark red colour are not suitable for this. For white wines, white wine varieties are used whose berry colour spectrum ranges from white, yellow and green to red. The wine lexicon in question describes around 1,700 grape varieties. For the individual countries there are tables with the varieties and quantities. See also under new varieties, grape variety and a list of relevant keywords under grapevine.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
