They have names like Jolly Elf, Indigo Rose, Orange Fizz, Baby Cakes and Cherry Buzz. They come in stop-sign red, deep ruby, golden yellow, chocolate brown and pale orange. They can look like a big gum ball or a plump olive. They are some of the more than 100 varieties of cherry and grape tomatoes that can be found on a list compiled by the Rutgers New Jersey Agricultural Experiment Station (njaes.rutgers.edu/tomato-varieties)…”People are attracted to small-fruited tomatoes due to the wide reputation they have for extra sweetness and probably subacid tartness compared to other tomatoes,” says Jack Rabin, of the Rutgers Agricultural Experiment Station.
