Temperature / 76–80°F / Turnip
Turnip at 76–80°F: 5.5 days
1.82× the speed of the 10.0-day baseline at 68°F. Target pH 3.80 · default salt 2.50%.
Temperature & timing
Most published recipes assume a 68 °F kitchen. Enter the base days for your recipe and the temperature you actually have — we return the adjusted fermentation time.
Safety at 76–80°F
Hot ferment zone. Approaching the upper edge of safety window for standard lacto-fermentation. Enzyme-softening of vegetable texture accelerates (cucumbers mush fastest here). Keep ferments under 7 days at this temperature. Mold risk on exposed surfaces rises — airlock or tight brine-seal mandatory.
At this range: Acceptable for kombucha (ideal range) and short lacto-hot-sauce batches (5-7 days). AVOID for sauerkraut — texture softens, flavor runs past optimal. Monitor twice daily at this range.
About turnip
Mild, peppery, slightly sweet. Featured in Middle Eastern torshi (pickled root mix) and regional kimchi variants. Absorbs flavor well from surrounding ferment. Shreds work better than chunks for sauerkraut-style.
Technique
Shred for sauerkraut blend (cabbage + turnip at 70/30). Brine-pickle as cubes: 2.5% brine, 10 days. For Lebanese torshi pink variety: add sliced beet (10% by weight) — turns turnips hot pink from beet pigment.

Frequently asked questions
How long does turnip take to ferment at 76–80°F?
About 5.5 days at 76–80°F (24.44–26.67°C) — 1.82× the speed of the 10.0-day baseline at 68°F. Start tasting from day 5 regardless of temperature; target pH is 3.80 or below.
Is 76–80°F safe for fermenting turnip?
Hot ferment zone. Approaching the upper edge of safety window for standard lacto-fermentation. Enzyme-softening of vegetable texture accelerates (cucumbers mush fastest here). Keep ferments under 7 days at this temperature. Mold risk on exposed surfaces rises — airlock or tight brine-seal mandatory.
What salt percentage for turnip at this temperature?
Salt percentage doesn't change with temperature — 2.50% by weight is still the default for turnip (workable range 2.00%–3.00%). Temperature changes speed, not the salt ratio.
