Is there such thing as red grapes?

Yes, there are definitely red grapes! They are actually a type of purple grape, which means their skin contains both red and blue pigments.

Here are some examples of red grapes:

* Concord grapes: These are the most popular type of red grapes in the US, used primarily for juice and jelly.

* Red Globe grapes: A large, seedless variety often found in grocery stores.

* Crimson Seedless grapes: Another seedless red grape, known for its sweet flavor.

* Zinfandel grapes: Used for making both red wine and raisins.

It's important to note that the term "red grape" can sometimes be used loosely to refer to any grape with red or purple skin, regardless of the specific pigments present.
