female grape varieties

In general, cultivated grapevines are monoecious (male and female flowers on the same plant), while wild vines are dioecious (separate on different plants). The cultivated monoecious vine has hermaphroditic flowers (hermaphrodites), meaning that the male and female sexual organs are united in one flower. Purely female wild vines have played an important role in the development of grape varieties.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
