Quote: There are a bunch of good treads on how to do it. I think it's a bit different depending on whether it's digital or analogue
For analogue I mix 1/2 cup of kosher salt (can't use anything with iodine in it) with 1/4 cup of water. Put it in a short cup and then put it in a ziplock with the hydrometer. Wait 8- 12 hours and read it through the bag to find out where 75% is at. I'm pretty sure someone else can explain it better than I can.![]()
