Salt grain

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

Based on Fine sea salt at 5.69 g/tsp.

Flavour-forward. Ferment will be slower; brine will taste salty. Good for pickles and hot-sauce mashes that need long shelf life.

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.

Fermentation data

Default salt: 3.5%(you are viewing 4%)
Salt range: 3–5%
Time at 68°F: 7.0 days
pH target: 3.60
Water content: 96%
Preferred styles: brine pickle half sour, brine pickle full sour

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 4%

Never use 4% for final dry-salted sauerkraut — way too salty. Only for pre-ferment rinse stages or for dilute brines (kvass) where the resulting beverage is drunk diluted or cooking vinegar.

Safety: Flavour-forward. Ferment will be slower; brine will taste salty. Good for pickles and hot-sauce mashes that need long shelf life.
