What brine % should I use to cover a mash? I use the sauerkraut method of 3tbls of salt for every 5 lbs of peppers when making the mash. Sometimes there is not enough nature liquid to cover the mash so I add some brine to make sure it is completely submerged. I know not everyone does this but f I am going to use a bribe to cover the mash what percentage should it be? I have read everything from 2% to 10%.
