Lacto-fermenting garlic: 2.50% salt, 21.0days at 68 °F
Lower water content (59%) means garlic ferments slowly and benefits from honey or brine as carrier. Fermented honey-garlic is traditional medicine across cultures. Note: honey-ferments are NOT lacto-ferments — they rely on natural yeasts + lactic bacteria from the garlic itself once diluted; honey alone is antimicrobial.

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 honey-garlic: peel whole cloves, submerge in raw honey (important — not pasteurized), loose lid (CO2 escape), flip daily for first 2 weeks, ferment 4-6 weeks. Mixture becomes thinner + darker + milder over time. Safe at room temp indefinitely due to combined honey + garlic antimicrobial action + resulting pH <4.5.
2.50% by weight is the default for garlic (workable range 0.00%–3.00%). For 1000g garlic, that's 25.0g salt. Use non-iodised salt and weigh in grams — teaspoon equivalences vary by salt grain. Source: Fermentation Culture — honey fermentation safety.
How long to ferment garlic?
21.0 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 3.50 or below indicates complete primary fermentation.
