Lacto-fermenting red beet: 3.00% salt, 10.0days at 68 °F
Earthy, sweet. Primary base for Eastern European beet kvass (lightly fermented beverage) and classic lacto-pickle. High natural sugars drive vigorous fermentation — watch for overflow in first 3 days.

Grain matters: one teaspoon of Diamond Crystal weighs half as much as one teaspoon of fine sea salt. Weigh in grams when you can.

Technique
For pickled slices: peel, slice 5mm, cover with 3% brine + caraway + bay leaf, 10-14 days. For kvass: chunk raw beets fill jar 50%, cover with 3% brine, ferment 7-10 days, strain, drink or use as cooking vinegar. Second ferment of kvass with a fresh beet slice intensifies flavor.
3.00% by weight is the default for red beet (workable range 2.50%–4.00%). For 1000g red beet, that's 30.0g salt. Use non-iodised salt and weigh in grams — teaspoon equivalences vary by salt grain. Source: Sandor Katz — Wild Fermentation (kvass).
How long to ferment red beet?
10.0 days at 68°F (20°C). Cooler kitchens (60-65°F) slow fermentation; warmer kitchens (75-80°F) roughly halve the time per 10°F increase. Start tasting from day 5; target pH 3.80 or below indicates complete primary fermentation.
