I'm struggling with technique for taking good gravity readings. Do all you guys actually draw off some wort or beer into the little cylinder that comes with the hydrometer each time you take a reading, or do you just float the thing in the bucket and read it there? How do you deal with getting a good read through the foam, etc. that is always present at the interface of the scale and the liquid?
I bet this is a dumb question, but then I'm told there are no dumb questions, just a lot of inquisitive idiots.
