Tomato varieties break into four main groups by shape and use
Tomatoes fall into four broad categories based on their shape, size, and what they're best for in the kitchen: slicing tomatoes, cherry tomatoes, paste tomatoes, and heirloom tomatoes. Each type has different flesh density, seed content, and flavor intensity. Knowing which is which helps you pick the right one for salads, sauces, canning, or eating fresh off the vine.
The category a tomato belongs to affects how it cooks, how long it stores, and how much water it releases when you cut it. A cherry tomato will burst and release juice quickly; a paste tomato holds its shape and has less water. Understanding these differences means you won't end up with a watery salad or a sauce that takes twice as long to reduce.
Key Takeaways
- Slicing tomatoes are large, juicy, and best eaten fresh or in salads because their high water content makes them poor for sauce.
- Cherry and grape tomatoes are small, sweet, and sturdy enough to roast whole or toss into dishes without falling apart.
- Paste tomatoes have thick flesh, few seeds, and low water content, making them the standard choice for canned sauce and tomato paste.
- Heirloom tomatoes come in many shapes and colors but are generally thinner-skinned and more delicate than modern hybrids, so they spoil faster.
- The variety name on a seed packet or plant label tells you the type; common slicing varieties include Brandywine and Beefsteak, while San Marzano is the classic paste tomato.
Slicing tomatoes: large, juicy, and best fresh
Slicing tomatoes are the biggest category and the ones most home gardeners grow. They range from 4 to 12 ounces and have thin skin, lots of juice, and a hollow center with many seeds. The flesh is soft and breaks apart easily, which is why they're perfect for sandwiches, salads, and fresh eating but poor for cooking down into sauce.
Common slicing varieties include Brandywine, Beefsteak, Early Girl, and Big Boy. Brandywine is prized for flavor but takes longer to ripen and cracks easily in rain. Beefsteak varieties are meaty and hold their shape better on a plate. Early Girl ripens faster in cool climates. These tomatoes store at room temperature for a few days but soften quickly once fully ripe, so eat them within a week of picking.
Slicing tomatoes are not good for canning or long-term storage because their high water content means you'd have to cook them for hours to get a thick sauce. If you want to preserve them, freeze them whole or make fresh salsa instead.
Cherry and grape tomatoes: small, sweet, and sturdy
Cherry tomatoes are roughly the size of a marble to a grape and weigh less than an ounce each. They have thin skin, are very sweet, and contain more seeds relative to flesh than larger varieties. Grape tomatoes are similar but slightly smaller and more oval. Both types are dense enough to hold their shape when roasted, grilled, or tossed into hot dishes, unlike slicing tomatoes which collapse.
Popular cherry varieties include Sungold (orange, very sweet), Sweet 100 (prolific, classic flavor), and Black Cherry (dark red, rich taste). Grape varieties like Campari and Cocktail are bred to be snacking tomatoes and store well at room temperature for up to two weeks. Because they're small and sturdy, they're ideal for skewering, halving for appetizers, or roasting whole at high heat.
Cherry and grape tomatoes are not suitable for sauce because you'd need to process a huge number of them to get a small amount of liquid. They're also not ideal for canning whole because they're harder to pack into jars efficiently.
Paste tomatoes: thick, dense, and made for sauce
Paste tomatoes, also called processing or sauce tomatoes, are medium-sized (2 to 4 ounces) with thick flesh, few seeds, and low water content. They're bred specifically for cooking down into sauce, paste, or juice because they reduce quickly and produce a thick, concentrated result. The flesh is meaty and holds together during long cooking.
San Marzano is the most famous paste variety and is considered the gold standard for Italian sauce. Roma is the most common American paste tomato and is reliable and prolific. Other varieties include Amish Paste, Opalka, and Plum. These tomatoes are not pleasant to eat fresh because they're bland and have a dense, dry texture. They're meant to be cooked.
If you plan to make tomato sauce, salsa, or paste at home, grow paste tomatoes. A single plant produces enough fruit to make several jars of sauce. They also freeze and can well, so they're the best choice if you want to preserve your harvest for winter.
Heirloom tomatoes: diverse colors and shapes, thinner skin
Heirloom tomatoes are open-pollinated varieties that have been grown for decades or centuries, passed down through families or preserved by seed companies. They come in nearly every color—red, pink, yellow, orange, green, purple, and striped—and in many shapes: round, oblong, ribbed, or irregular. Because they're not bred for commercial shipping, they have thinner skin and are more delicate than modern hybrids.
Popular heirlooms include Brandywine (large, pink, excellent flavor), Cherokee Purple (dark red, complex taste), Green Zebra (green with yellow stripes, tangy), and Mortgage Lifter (very large, meaty). Heirlooms are prized by home gardeners for flavor and novelty but are slower to ripen, more prone to cracking in rain, and spoil faster than hybrids. They're best eaten fresh within a few days of picking.
Heirloom tomatoes are not a separate category by function—they can be slicing, paste, or cherry types—but rather a classification by breeding history. Many heirlooms are slicing tomatoes, so they share the same drawbacks for sauce-making. If you grow heirlooms, plan to eat them fresh or give them away quickly.
How to identify which type you're growing
The easiest way to know what type you have is to read the seed packet or plant label. It will say "slicing," "cherry," "paste," or "heirloom," or it will name the variety, which you can then look up. If you're buying a plant at a nursery and the label is missing, ask the staff or take a photo of the plant tag to search online.
If you're trying to identify a tomato you've already picked, look at the size and shape. Anything under 2 ounces is likely cherry or grape. Anything 4 ounces or larger with thin skin and lots of juice is likely a slicing tomato. A dense, meaty tomato with few visible seeds and an oblong or plum shape is likely a paste tomato. Color and skin texture vary too much to be reliable on their own.
When you're at a farmers market or grocery store, the label or the produce person can tell you the variety. Knowing the name helps you decide whether it's good for your intended use. If you want to make sauce, ask for San Marzano or Roma. If you want a salad, ask for Brandywine or Beefsteak.
Hybrid versus open-pollinated varieties
Most modern tomatoes sold in grocery stores and garden centers are hybrids, meaning they're bred by crossing two parent plants to get specific traits like disease resistance, uniform ripening, or longer shelf life. Hybrids are reliable and productive but don't breed true—seeds saved from a hybrid plant won't grow the same tomato next year.
Open-pollinated varieties, including heirlooms, can be pollinated by insects or wind and will produce seeds that grow into identical plants. This is why heirlooms and other open-pollinated types are popular with gardeners who want to save seeds year to year. Open-pollinated tomatoes are often more flavorful but less uniform and more prone to disease.
For a home gardener, the choice comes down to what matters most: reliability and disease resistance (choose hybrids) or flavor and the ability to save seeds (choose open-pollinated). Many gardeners grow both. The type—slicing, cherry, paste—is separate from the breeding method, so you can find hybrid or open-pollinated versions of most categories.
Frequently Asked Questions
Can I use a slicing tomato to make sauce?
You can, but it's inefficient. Slicing tomatoes have so much water that you'd have to cook them for hours to get a thick sauce, and you'd need many more tomatoes than if you used paste varieties. If you only have slicing tomatoes, strain them through a fine sieve or cheesecloth to remove excess liquid before cooking.
What's the difference between a cherry tomato and a grape tomato?
Grape tomatoes are smaller and more oval, while cherry tomatoes are rounder and slightly larger. Grape tomatoes are often a bit firmer and store slightly longer. Both are sweet and work the same way in cooking, so the choice is mostly about preference and what's available.
Do heirloom tomatoes taste better than hybrids?
Many heirlooms have excellent flavor, but not all. Some hybrids are also delicious. Flavor depends on the specific variety, growing conditions, and ripeness more than on whether it's an heirloom. The best approach is to try a few varieties and see which ones you prefer.
Can I save seeds from my tomato plants?
Yes, but only from open-pollinated or heirloom varieties. Seeds from hybrid plants won't grow the same tomato. To save seeds, let a ripe tomato ferment in water for a few days to remove the gel coating, rinse the seeds, dry them completely, and store them in a cool, dry place.
Which tomato type is best for growing in containers?
Cherry and grape tomatoes are ideal for containers because they're smaller plants and produce abundantly in limited space. Determinate (bush) varieties of slicing tomatoes also work well. Paste tomatoes and large heirlooms need more root space and are better in the ground or very large pots.
