Grape tomatoes are a variety of the tomato plant, Lycopersicon esculentum. Specifically, the grape tomato resembles a grape in shape, oblong and small, and in sugar content. It is naturally sweeter than a cherry or plum tomato variety. The grape tomato is thought to be a cultivar from southeast Asia and was introduced in the 1990s. This small, bite sized sweet grape tomato variety is very popular in restaurants and is used in many recipes due to its highly pleasing flavor, color, and texture.
