A grape tomato is a small, usually oblong tomato. They are similar in size to a small cherry tomato and they both have a similar taste, but the grape tomato also has the similar oblong shape of a plum tomato. The tomatoes were introduced to the United States market in 1997 by grower Andrew Chu, who got them from Taiwan's Known-You Seed Co, though the majority of the production is by a company called Procacci Brothers, who market them as "Santa Sweets". They are considered a difficult crop to grow, as they do not produce as heavily as many cherry tomato varieties.
