Great White Tomatoes — A Low-Acid Ivory Beefsteak
Great White is a large ivory-white beefsteak heirloom with a mild, sweet, genuinely complex flavour and almost none of the acid bite of a red tomato. The fruit ripens to a creamy pale yellow-white, often with a faint peachy blush where the sun hits it, and the flesh inside is dense, meaty, and nearly seedless — closer to solid fruit than juice and gel. Individual tomatoes run large, typically 225–450g (8–16 oz), with some topping 500g in a warm season.
What sets this variety apart is that it delivers gentleness without going flat. Most low-acid tomatoes trade away depth for softness; Great White keeps the full-bodied character of a good beefsteak while dropping the sharpness, which makes it one of the first varieties worth trying for anyone who finds standard tomatoes harsh. The plants are vigorous indeterminate growers that fruit until frost, so a single plant well supported can carry a heavy load of big, pale tomatoes through late summer.
🇺🇸 US: An annual coast to coast, best where summers run long and warm — the Great Lakes, Mid-Atlantic, Southeast, Pacific Northwest, and California. In the Deep South, set plants out in early spring or early fall so fruit sets before peak heat.
Best for: fresh slicing, heirloom tasting plates, low-acid diets, caprese, and colour-contrast tomato salads.
🌱 How to Grow Great White Tomato Seeds
Start Great White seeds indoors 6–8 weeks before your last frost, sowing 6mm (¼ in) deep at 21–27°C (70–80°F); seedlings emerge in 6–10 days. Grow them under 14–16 hours of bright light to keep the stems stocky, and pot up into 10cm (4 in) containers once the first true leaves appear. Harden the seedlings off over 7–10 days before transplanting, and set them out only after frost has passed and nights stay above 10°C (50°F).
Space plants 75–90cm (30–36 in) apart in full sun — this is a big, sprawling indeterminate that needs room. Bury the stem deeply at transplant so roots form along it, and install a heavy cage or double stake at planting; the large fruit puts real weight on the branches. Work compost into the bed and start a balanced tomato feed once flowers appear. Calcium matters most for big beefsteaks: mix bone meal or crushed eggshells into the planting hole to head off blossom end rot, and water deeply and evenly, since uneven moisture cracks large fruit.
🍅 Harvesting & Preserving Great White Tomatoes
Great White tomatoes are ripe when the skin shifts from bright white to a creamy ivory-yellow and the fruit feels like a ripe peach — soft under gentle pressure, not firm. Colour alone won’t tell you; go by feel, by the easy release from the vine, and by the ripe tomato fragrance at the stem end. Pick promptly, because these big pale fruits crack or collapse quickly if left too long, especially after rain.
Great White is a fresh-eating tomato with a shorter shelf life than firmer types, so eat within 3–5 days of harvest, stored at room temperature out of direct sun — never refrigerated. When a glut hits, the dense low-seed flesh preserves beautifully: halve and slow-roast at 120°C (250°F) for 2–3 hours for a jammy, concentrated spread, or freeze roasted halves in bags for winter. The pale colour is a practical bonus in the kitchen — it doesn’t bleed into other ingredients.
🍽️ Cooking with Great White Tomatoes
Great White tomatoes shine as a slicer, where the mild sweetness carries a plate on its own. Thick ivory rounds with flaky salt, basil, and good olive oil make a striking presentation, and against red and orange heirlooms in a mixed platter the pale flesh adds both colour contrast and a gentler flavour note. The low acidity makes this the go-to tomato for anyone who wants full tomato character without the bite.
Cooked, this variety holds its own. The meaty, low-seed flesh makes a mild, slightly sweet fresh salsa, and it slow-roasts into a deeply concentrated spread that’s remarkable on toast or tossed through pasta. Because the colour stays pale, Great White won’t muddy a dish the way a dark tomato can — useful in creamy sauces and light summer preparations where you want the flavour without the red.
🫙 Saving Great White Tomato Seeds
Saving Great White seeds is easy because the variety is open-pollinated and grows true to type. Scoop the seeds and gel from a fully ripe, well-formed fruit into a jar with a splash of water and ferment at room temperature for 2–3 days, until a film of mould forms and breaks down the coating around each seed. Pour off the mould and any floating seeds, rinse the good seeds that sank, and dry them on a plate or coffee filter — not paper towel, which they stick to — for 1–2 weeks before storing.
As an open-pollinated heirloom, Great White is not a hybrid, so its seed comes true — but tomatoes can occasionally cross-pollinate when insects move between nearby varieties. For pure seed, separate different tomato varieties by about 3m (10 ft) and save from your best-flavoured, most typical fruit; keeping the line isolated is especially worth it to hold the pale colour and low-acid profile. Stored cool, dark, and dry, tomato seeds stay viable for 4–6 years, and a quick paper-towel test on a few seeds each spring confirms the batch.
