1.5% salt for Napa Cabbage

About Napa Cabbage

The standard kimchi base. Napa cabbage has looser, more water-dense leaves than green cabbage. Traditional Korean preparation salts at higher % (3.5-5%) during a pre-ferment brining stage to draw water and soften leaves before the paste is added.

Technique

Quarter cabbage lengthwise. Dry-salt at 4% by quarter weight, rest 2-4 hours flipping halfway. Rinse 3x in cold water to remove excess salt. Toss with kimchi paste (gochugaru, ginger, garlic, fish sauce or alternative, carrot, scallion, radish). Pack into jar leaving 2cm headspace. Ferment 3-7 days at 65-70°F then transfer to fridge.

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.
