Why are red grapes called grapes?

Red grapes, like all other grapes, are called "grapes" because of their botanical classification.

Here's a breakdown:

* Genus: *Vitis* (meaning "vine" in Latin)

* Species: *Vitis vinifera* (the most common type of grape used for wine)

The word "grape" itself is derived from the Old English "grape", which likely originated from Proto-Germanic "grapo", meaning "cluster of fruit".

So, the name "grape" refers to a specific type of fruit produced by the *Vitis* vine, regardless of its color.

While we often use "red grapes" to distinguish them from other varieties, it's important to remember that the term "grape" encompasses all the fruits produced by these vines.
