A Guide to Heirloom Tomatoes

A Guide to Heirloom Tomatoes I’ll let you in on a little secret: I never liked fresh tomatoes. Until, that is, I had my first heirloom tomato. You’ve probably had an heirloom tomato at least once or twice—you might even grow them in your garden or pick them up at the farmers market. They’re everywhere in August; they make a great addition to nearly any dish, or a marvelous snack (or dinner) on their own. Here’s everything you need to know about the best (edible) part of summer:

what does ‘heirloom’ even mean?

Heirloom, also called Heritage, refers to varieties of tomatoes whose seeds have been passed down for generations because of desired qualities and characteristics. Basically, they are older varieties (but not always!) of tomatoes that are prized due to their unique colors, flavors, textures and characteristics. Heirloom varieties are open-pollinated. You can save seeds from the heirloom tomatoes, plant them, and they will grown into new tomato plants. If two or more varieties are planted near each other, you never know—you might end up with a new mystery variety!

Heirlooms are classified into four specific categories:

Family Heirlooms: Seeds are gathered and passed down within a family through the generations.

Commercial Heirlooms: Varieties that were introduced before the 1940s, are open-pollinated and have been in circulation for more than 50 years.

Created Heirlooms: These tomatoes were created by hybridizing two known parents (either two heirlooms or an heirloom and a hybrid variety). The resulting seeds are dehybridized for several generations so that undesirable characteristics are eliminated, a process which can take eight to 10 years, or more.

Mystery Heirlooms: These varieties are created due to natural cross-pollination of heirloom varieties.

why are heirlooms so desirable?

Heirlooms usually haven’t been hybridized for qualities that include shelf life, color and uniform appearance. They are often “ugly” with deep cracks and bumps. The colors are variegated and range from deep browns and purples to light yellows, pinks and everything in between. The only color I haven’t seen is blue!

where can I buy heirloom tomatoes?

You will be able to find heirlooms at local farmers markets, and even some grocery stores. Because heirlooms are becoming more popular and in demand, they are more readily available than they once were. Whole Foods and Trader Joe’s usually have heirlooms year-round, but they are obviously better in the summer during normal tomato season. Buy local if you can. Often CSAs will also include heirlooms during the summer.

how do you select a good heirloom tomato?

Selecting heirloom tomatoes is different than your regular, run-of-the-mill red tomato. The colors are only the beginning of it. Each variety is valued for its unique flavors and textures. (See below for more on that subject.)

The first rule of thumb when shopping for heirlooms is to handle them with extreme care. Touching the heirlooms is often discouraged; a squeeze will earn you the evil eye from your grocer. The skins of heirlooms are thinner, the flesh is more prone to bruising, and therefore they spoil more quickly. Just give them a once-over and make sure the skin is intact (cracks are okay, but avoid splits that are oozing tomato juice). Avoid overly ripe tomatoes, too—if you won’t be using them the same day, buy some that are a little underripe.

When it comes to heirlooms, the uglier the better, I say. Cracks and bumps give them character.

how do you store heirloom tomatoes?

As I mentioned, heirlooms spoil very quickly. It’s best to enjoy them within 1-2 days of buying them. If you need to keep them for longer, choose some that are a little firmer and underripe. They will continue to ripen at room temperature. Do not under any circumstances refrigerate the tomatoes. It will ruin their glorious texture and flavor. Keep them on the counter in an area where they won’t be squished by other foods. To keep fruit flies away, cover them with a fine mesh sieve. Only once they’ve been cut should you store in the refrigerator.

why should you eat heirloom tomatoes?

Due to their lack of commercial hybridization, heirlooms are actually a little lower in lycopene than strictly red tomatoes. But they are full of vitamins A and C, minerals and fiber, and support cardiovascular and bone health. Not to mention they are life-changing in their sweet flavor and juicy, almost buttery texture.

what are the heirloom tomato varieties?

Too many to count! Here are some popular ones:

how do you prepare heirloom tomatoes?

Just as you would any tomato. They are at their best when eaten raw, but make glorious salsas, fresh or cooked pasta sauces, and fresh juice. Heirlooms can even be bottled or dehydrated to preserve a bountiful garden harvest. Get 15 gorgeous heirloom tomato recipes here!

    I’m with you – if you want to learn to love tomatoes, then eat an heirloom tomato. We are growing 3 different types of heirlooms this year – homestead, Golden Jubilees, and Black Prince (a large version of the Black Zebras. They are ALL awesome! I’m going to have look for some of the varieties that you mentioned above. I’ve never heard of Black Brandywine.
