Quick answers
What does a Tasmanian Chocolate tomato taste like?
Rich and smoky with the depth of a dark heirloom and balanced, fairly low acidity. It is far more flavorful than most compact tomatoes.
How big do Tasmanian Chocolate tomatoes get?
About eight to twelve ounces, which is large for a dwarf plant, so one slice is enough for a sandwich.
How tall does the plant get?
Compact, usually two to three feet, which makes it well suited to large pots and small beds.
Determinate or indeterminate?
It is a dwarf, a compact plant that stays short but keeps setting fruit over the season. Give it a short cage for the heavy fruit.
Can I save the seeds?
Yes. Tasmanian Chocolate is open pollinated, bred by the Dwarf Tomato Project, so saved seed grows true to type.
What is the Dwarf Tomato Project?
A global effort by volunteer breeders to create compact dwarf plants with heirloom flavor, released as open pollinated varieties you can save.
The Full Guide

The Big Flavor Gap Nobody Warns You About

The Tasmanian Chocolate tomato has a great reputation on paper. Its breeders describe it as full, balanced, and delicious.

Then you read what actual home growers say. More than one reports the fruit tasting bland, almost flavorless off the vine.

Both things can be true, and the reason comes down to how you grow it. This dwarf variety hides a specific trap that quietly robs the fruit of flavor.

This guide covers that trap and how to avoid it. You also get the full story and a complete growing plan for the Tasmanian Chocolate tomato.

What the Tasmanian Chocolate Tomato Is

This variety came out of the Dwarf Tomato Project, a global volunteer breeding effort. It started as a 2006 cross between New Big Dwarf and Paul Robeson, made by Patrina Nuske Small in Australia.

A grower named Linda Reid in Tasmania later selected and named the final variety. Victory Seed Company introduced it around 2010 as one of the project’s first releases.

The Dwarf Tomato Project pledged this variety to the Open Source Seed Initiative. That keeps the seed free for anyone to grow, save, and share. It is part of why the variety spread so widely among home gardeners.

The plant is a true dwarf, not a determinate or a standard vine. It stays compact at 3 to 4 feet tall, with thick central stems and dark, crinkled foliage called rugose leaves.

Days to maturity land around 65 to 85 days depending on your conditions. The variety is open pollinated, so saved seed grows true, apart from the occasional off type plant.

Why a Dwarf Is Not the Same as a Determinate

People often lump dwarf tomatoes in with determinate bush types. They are genuinely different, and the difference matters for how you grow this one. Confuse the two and you will prune it wrong or expect the wrong harvest pattern.

A determinate tomato grows to a set size, sets most of its fruit at once, then winds down. A dwarf grows slowly on a stout central stem and keeps producing over a long season, more like an indeterminate.

So the Tasmanian Chocolate tomato gives you a compact, roughly waist high plant. Yet it keeps flowering and fruiting for months, which is unusual for something this small.

That combination is the whole appeal of the dwarf class. You get a long harvest window from a plant that fits a container or a tight bed.

Dwarfs are sometimes called tree type tomatoes because of that thick, upright central stem. It gives the plant a sturdier frame than a floppy indeterminate vine. Even so, it still needs support once fruit loads up.

What It Looks Like

Fruit is oblate, meaning slightly flattened, and ripens to a deep mahogany brown. The color sits close to Cherokee Chocolate, one of its flavor cousins.

Individual tomatoes are large for a dwarf, often 5 to 12 ounces. Getting fruit that size on a plant this small is a real achievement of the breeding project.

Fruit forms in clusters along the sturdy central stem rather than on long trailing branches. That tidy structure is exactly why the plant works so well in a pot.

The foliage is dense, dark green, and heavily textured. That thick canopy looks healthy, but it is also the source of the flavor problem covered below.

Flavor and Best Uses

At its best, this is a rich, savory, well balanced brown tomato. Brown and chocolate tomatoes tend to carry a deeper, almost smoky flavor that fans love.

But firsthand grower reports are genuinely mixed. Several describe the fruit as disappointingly mild, better in a cooked sauce than eaten fresh.

The good news is that this gap is mostly fixable through how you grow it. Nail the growing conditions and the Tasmanian Chocolate tomato rewards you with the flavor its breeders promised.

Use ripe fruit fresh in salads and on sandwiches where its color really stands out. It also cooks down into a rich, deeply colored sauce. That is where even the milder tasting fruit still earns its keep.

The Real Reason the Flavor Falls Flat

Here is the trap. The dense, rugose canopy that makes this dwarf look so lush also shades its own fruit.

Oregon State University Extension explains that the more sunlight a plant gets, the more sugar it makes through photosynthesis. Less light means less sugar, and less sugar means flatter flavor.

On a dense dwarf, fruit often ripens buried deep inside shaded foliage. One grower even reported fruit cramped in the crowded center of the plant, barely able to develop.

The fix is the same practice university sources already recommend for airflow and disease. University of Georgia Extension advises selectively removing foliage so more sun and air reach the plant.

For this variety specifically, thin the dense inner leaves so light actually reaches the fruit. That single habit does more for flavor here than any fertilizer trick.

Just do not overdo it. University of Georgia Extension warns that stripping too much foliage exposes fruit to sunscald. Aim for open and airy, not bare.

How to Grow the Tasmanian Chocolate Tomato

Our guide to growing tomatoes covers the fundamentals every variety shares. Here is what this variety needs specifically.

Seed Starting

Start seeds indoors about 6 to 8 weeks before your last expected frost. Use a sterile seed starting mix and keep it warm and evenly moist until germination.

Dwarf seedlings grow more slowly and stay stockier than standard tomatoes. Give them bright light so they stay compact rather than stretching toward a weak window.

Transplanting and Spacing

Harden seedlings off gradually over about a week before planting outside. Wait until nighttime temperatures stay reliably above 50 degrees.

Space plants about 2 feet apart, since the compact habit does not need wide rows. Bury the stem a bit deeper than it sat in its pot for stronger roots.

Growing in Containers

This is where dwarf varieties shine. The Tasmanian Chocolate tomato grows happily in a container, which suits a patio, balcony, or small yard.

Use at least a 5 gallon container, and a larger one is better given the heavy fruit load. Good drainage and consistent watering matter more in a pot than in the ground.

A container also lets you chase the sun, which matters a lot for this variety. Move the pot to your brightest spot to help the fruit develop full flavor.

Our guide to growing tomatoes in pots covers container growing in full.

Staking and Support

Do not let the small size fool you into skipping support. The stout stem still needs a stake or short cage, because the plant gets top heavy with large fruit.

Grower reports repeatedly mention plants leaning over under the weight of the crop. Stake early rather than trying to prop up a loaded plant later. A single stout stake or a short tomato cage is usually all it takes.

Light and Soil

Full sun is essential, at least 6 to 8 hours a day. Given the flavor issue, this variety arguably needs strong light even more than most tomatoes.

Grow it in loose, well drained soil rich in organic matter. A soil test before planting tells you exactly what your garden needs. Aim for a pH near 6.2 to 6.8 for the best results.

Watering and Fertilizing

Water deeply and consistently, keeping soil moisture even rather than swinging between dry and soaked. Steady moisture prevents cracking and blossom end rot.

Apply a balanced fertilizer at planting, then side dress lightly once fruit sets. Avoid heavy nitrogen, which pushes even more of that dense foliage at the expense of fruit.

Our guide to watering tomatoes covers the rhythm in more depth. And our guide to fertilizing tomatoes handles the feeding schedule.

Pruning and Thinning

This is the most important step for good flavor. Thin the dense inner foliage regularly so sun and air reach the developing fruit.

Remove the lowest leaves once the plant is established to keep foliage off the soil. Ellen Wells, a grower who reviewed this variety, specifically noted the packed leaves needed removing on a regular basis.

Companion Planting

Basil and marigolds make classic tomato companions, sharing similar sun and water needs. Both may help deter some common garden pests as a bonus.

In a container, keep companions modest so they do not crowd the dwarf’s roots or shade it further. This variety already struggles with too much shade, so give it the light rather than a neighbor.

Problems to Watch For

Poor flavor is the standout complaint, and it traces almost entirely back to shaded fruit and weak light. Thinning the canopy and giving full sun both fix it. Our tomato problem guide walks through the most common ones.

The dense foliage also traps humidity, which invites fungal problems like mildew. NC State Extension recommends improving airflow and removing lower leaves to lower that risk.

Fruit can end up cramped in the crowded center of the plant, limiting size. Light thinning opens up space for the fruit to develop properly.

Blossom end rot may appear as a dark, sunken spot on the fruit bottom during uneven watering. Consistent soil moisture is the most reliable prevention.

Watch for common pests like aphids and hornworms, which are easy to handpick on a plant this size. The compact frame actually makes scouting quicker than on a sprawling vine.

Because the plant is still stabilizing genetically, you may occasionally see an off type seedling. Simply cull any plant that does not match the true dwarf form.

For identification and treatment, our tomato disease guide covers the full list.

Harvest and Storage

Brown tomatoes are tricky to read for ripeness, since they never turn bright red. Watch for the green shoulders fading to a muddy brown and the fruit softening slightly.

Pick when the fruit gives a little to gentle pressure and comes away easily from the vine. Color alone will mislead you with this variety, so trust feel.

Store ripe fruit at room temperature rather than the refrigerator. Cold storage dulls the deep, savory flavor that makes brown tomatoes worth growing.

If a hard frost threatens, pick any fruit showing color and finish ripening it indoors. Brown tomatoes ripen off the vine just fine at room temperature.

How the Tasmanian Chocolate Tomato Compares

Against Cherokee Chocolate, a full sized brown heirloom, this variety offers similar color and flavor on a far smaller plant. Cherokee Chocolate wins on peak flavor, while this one wins on space.

Against other dwarfs like Rosella Purple or Sweet Adelaide, this one stands out for its larger fruit size. Growers consistently note being surprised by how big the fruit gets on such a small plant.

Against a determinate patio tomato, the Tasmanian Chocolate tomato gives a longer harvest window. It keeps producing for months instead of ripening everything at once.

Against Paul Robeson, one of its own parent varieties, this dwarf trades a little peak flavor for a far more compact, container friendly plant. Paul Robeson is a full sized vine, while this one fits a pot on a balcony.

Saving Your Own Seed

Because this is an open pollinated variety, saved seed grows true to type. Choose fruit from your healthiest, most typical looking plant to save from.

Scoop out the seeds and ferment them in a small jar of water for a couple of days. Rinse them well, then dry them completely before storing.

The variety is still stabilizing, so watch for the occasional off type plant. Save seed only from plants that clearly match the true dwarf form and brown fruit. Doing this every year slowly locks the strain in for your own garden.

The Verdict

The Tasmanian Chocolate tomato is a genuinely clever plant, a big brown beefsteak on a container sized dwarf. That alone makes it worth a spot in a small garden.

Just go in knowing the flavor is not automatic. Thin that dense canopy, give it strong sun, and you get the rich taste its breeders designed it for.

For gardeners short on space who still want a real, full flavored slicing tomato, this variety delivers. It is also a living piece of one of the most successful open source breeding projects in tomato history.

Grow it in your sunniest spot and stay on top of thinning that thick canopy. Do those two things and the flavor complaints simply stop being your problem.
