While this is not my first post, it is my first batch. I have another question. (the hell you say? lol) I'm a few days away from the first month mark and the batch is clearing nicely. Being as how I have never brewed before, I am concerned with the film, gunk, muck, crappola, or whatever the more technical term is for the stuff that is on the walls of my glass jug. It is the same color as the lees. I have told my wife that it is probably normal. I figured I would ask the masters.;D On my next one gallon batches I was going to try a hydrometer but how do I use it on a gallon jug? I have read of people taking a test sample in another container. Will I be able to pour the tested liquid back into the fermenter or am I out the test liquid? I only ask this because a gallon isn't much to work with. Thanks in advance!
