Because tomatoes are in season in summer, many people might think they taste best then. However, tomatoes are actually vulnerable to heat and humidity and prefer cooler conditions. Summer tomatoes grow quickly and get big before their sugar content increases, so they’re widely distributed nationwide. Spring tomatoes, on the other hand, grow more slowly, and their sugar content rises at a gentler pace, resulting in a richer, sweeter flavor.
