OK, I did my first starter the other day. After 24 hours I put it in the 'fridge and the yeast settled to the bottom of the jug. Today I'm brewing and took it out to warm up to room temp while I brewed. In the process of warming up it the wort that was on top became cloudy again, almost like the yeast started working again. Is this normal? I'm just going to pour the whole starter in the brew wort once it's cooled down enough. This shouldn't be a problem, should it? Thanks.
