Hydrometers You need one, here is how to use one

So dumb question here.
I’m on my 4th Brew and haven’t used a hydrometer before.

I know. I know. Save it. I have one coming tomorrow from Amazon :slight_smile:

So here’s my Q. I’m about to bottle bit will save some to test tomorrow.

Do I take a reading before or after priming sugar solution is added? I could see it going either way, but would assume id get a different reading each way.

What would be proper?

Thanks!
