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.
