1.5% salt for Kirby Cucumber

About Kirby Cucumber

Kirby (aka pickling) cucumbers are bred for fermentation: small (4-6 inches), thick-walled, low seed count, no wax coating. Grocery-store English or slicing cucumbers fail because their wax blocks brine penetration and their thin skin softens to mush.

Technique

Use brine-pickling method, not dry-salt. Cover cucumbers completely with 3.5% brine (35g salt per liter water). Weigh down to keep submerged. 3-5 days at 68-72°F for half-sour (still crunchy, mildly tangy), 10-14 days for full-sour. Add 1 dill head + 2 cloves garlic per quart for classic flavor. Grape or oak leaf adds tannin for crunch.

Salt level notes at 1.5%

Only for experienced fermenters who can control temperature and inspect daily. Not a beginner salt level — the safety margin is too thin. If testing, start at 2% and only reduce after 5+ successful 2% ferments.

Safety: Safe range for lacto-fermentation. 2% is the most common default for cabbage, kimchi and pepper mash.
