Sacramento, CA -- Ever wonder why grapes come in different colors?

Researchers who have studied the question say they've traced color to a specific gene.

That gene causes white grapes to have little color, and also influences the color of red and green grapes.

By identifying that gene, scientists say they may be able to breed color-specific grapes or grapes that enhance the quality of wine and juice.

Researchers add that the knowledge might allow them to develop grapes with unusual colors."

My comment: Wait and see.
