How the brine calculator works
Brine percentage describes salt as a percentage of a chosen weight. FermentWise supports the two methods most commonly encountered in vegetable fermentation recipes.
Total-weight brine
(water + vegetables) × salt % = saltUseful when a recipe defines salt relative to everything in the jar, excluding the salt itself.
COMMON QUESTIONS
Brine calculator FAQ
How much salt is in a 2% brine?
A 2% water-based brine uses 20 grams of salt for every 1,000 grams or milliliters of water.
Should I use water weight or total weight?
Follow the method specified by your recipe. Water weight is common for a separately mixed brine. Total weight is useful when salt is defined relative to the combined vegetables and water.
Can I measure salt with teaspoons?
A scale is more reliable. Different salts have different crystal sizes, so the same volume can contain noticeably different weights.
