Think, “Grandpa's backyard garden.” These are the classic, first generation tomato varieties. The numerous Heirloom varieties offer a diverse array of sizes, shapes, flavors and textures. These are the tomatoes you would want on hand when you’re looking for a flavor that smacks of garden fresh tomatoes. Eat them on their own and you’ll recapture the flavors of tomatoes grown in your grandparent’s backyard.
