Default cold crashing visible layers

Hi everyone,

I just kegged a low ABV (3.5%) version of Schlenkerla's Quaffable Irish Red (All Grain). This was a bit of an experiment in that I wanted to go from grain to glass pretty quickly due to a bit of a homebrew shortage. I brewed it last Sunday Jan 22, it only took a few days to ferment out. On Saturday Jan 28 I took a hydrometer reading and it was at 1.010. The sample was still a bit cloudy of course so I decided to start cold crashing hard. I set my ferm chamber to 1.5 degrees C (34.7 F) and after checking the clarity of a sample this evening (nice and clear) I decided to keg it.

While racking I could see a visible clear layer on top and got wondering... first of all I damn well hope that's not alcohol on top! Maybe it's just color compounds settling out.

I was going to put the pics inline but they're a little on the big side. Links:

Is this normal? I'm guessing it is, and not too worried. I did crash it pretty cold.

Thanks,
-Rob

Default

Its just clearing. Alcohol will not separate until you start to freeze the liquid and even then it does not layer out like that.
