Cherry tomatoes are generally much sweeter than large tomatoes. The size and color of cherry tomatoes have a wide range, as there are hundreds of varieties. The perfect cherry tomato will be, first and foremost, in-season. It should be almost firm, thin, and smooth-skinned. The flavor will be a fine balance of sweet and tart. Like all tomatoes, cherry tomatoes can be classified based on how they grow, as their plants produce in two different forms: determinate or indeterminate. Determinate varieties grow on bush-like plants with short vines and bear just one crop per season, while indeterminate varieties are long, sprawling vine plants that bear fruit continuously throughout the season.
