Harvesting heirloom tomato plants is a rewarding experience for gardeners who value flavor, history, and variety. This list covers essential heirloom tomato varieties known for outstanding harvest qualities and practical tips for picking and storing your tomatoes. Whether you’re a seasoned grower or a beginner looking to expand your garden, these heirloom tomatoes and harvesting insights will help you enjoy the best fruit from your plants.
Brandywine
Brandywine tomatoes are one of the most famous heirloom varieties, prized for their large, pink fruits and exceptional sweet, rich flavor. They typically mature in about 80 to 100 days and produce beefsteak-sized tomatoes that can weigh up to one pound each. Brandywines are worth harvesting when the fruit feels slightly soft but still firm, with a deep pink color and a faint aroma, ensuring peak flavor.
Cherokee Purple
Cherokee Purple tomatoes are known for their dusky, dark reddish-purple skin and complex, smoky flavor profile. This variety ripens mid to late season and yields medium to large fruits with a tender texture. Harvesting when the fruit has a uniform dark color and slight give to gentle pressure ensures the best taste and juiciness, perfect for fresh eating or sandwiches.
Mortgage Lifter
Mortgage Lifter tomatoes are famous for their large size—often over one pound—and smooth, deep red skin. Developed in the 1930s, this variety produces a sweet, mild flavor with meaty flesh and few seeds. Harvesting is ideal when the tomatoes have a consistent red hue and yield slightly under gentle pressure, which guarantees a juicy and flavorful bite.
Green Zebra
Green Zebra tomatoes stand out with their unique green and yellow striped appearance and tangy, slightly tart flavor. They mature earlier than many heirlooms, often within 70 days, and produce small to medium-sized fruits. Harvest when the stripes turn bright yellow and the tomato softens slightly; this balance of ripeness preserves its signature zing and crisp texture.
Black Krim
Originating from the Crimean Peninsula, Black Krim tomatoes are dark reddish-brown to almost black with a rich, slightly salty taste. They are typically medium to large in size and ripen mid-season. To harvest, wait until the fruit has a deep, consistent color and a soft touch, which ensures the full development of their sweet, smoky flavor.
Amish Paste
Amish Paste tomatoes are prized for their use in sauces and canning due to their dense, meaty flesh and low seed count. They produce large, plum-shaped fruits with a bright red color and a balanced sweet-tart flavor. Harvest these when the fruit is fully red and slightly soft to the touch, ideal for processing or fresh cooking.
Paul Robeson
Paul Robeson tomatoes are a Russian heirloom variety known for their dark maroon color and intensely rich, smoky flavor with hints of sweetness. The fruits are medium to large and round, ripening mid to late season. Harvest at full color with a gentle give to avoid underripe acidity and enjoy a gourmet eating experience.
San Marzano
San Marzano is a classic Italian heirloom tomato renowned for its elongated shape and thick flesh, making it a favorite for sauces and canning. It ripens in about 80 days and produces bright red fruits with a sweet, low-acid flavor. Harvest when the fruit is fully red and firm yet yielding slightly to pressure for optimal sauce quality.
Costoluto Genovese
Costoluto Genovese tomatoes are ribbed, deep red fruits originating from Italy, valued for their rich, tangy flavor and meaty texture. They tend to be medium to large and have a unique heavily ribbed appearance. Harvest when the fruit has turned a deep red and feels slightly soft for the best balance of acidity and sweetness.
Yellow Pear
Yellow Pear tomatoes are small, pear-shaped fruits with a bright yellow color and a sweet, mild flavor. They are prolific producers, often yielding large clusters of fruit ideal for snacking or salads. Harvest these when they turn a vibrant yellow and are firm but not hard, providing the best flavor and texture.
How to Choose
When selecting heirloom tomato varieties to grow and harvest, consider your climate, space, and intended use. Flavor profiles range from sweet to tangy to smoky, so pick varieties that suit your palate and culinary goals. Also, factor in days to maturity; some heirlooms take longer to ripen, which may not suit shorter growing seasons. Disease resistance varies, so check if the variety is prone to common tomato diseases in your area. Finally, think about fruit size and shape depending on whether you want slicing, sauce, or snack tomatoes.
