Separation

I didn't notice this earlier; however, when I brought my beer into the kitchen from the closet, it appears to have some separation at the top. At first I thought it was an illusion created by the curvature of the carboy; but, on closer inspection it is really there. There is a dark band at the top ~3/4" wide, then another just over 1/2" wide below it (slightly lighter), then the rest is similar in color throughout (the lightest). It is a Weizenbier (from TJOHB), with the addition of some biscuit malt. I have had it in the primary for 3 weeks, the last week to 10 days it has been in an outside closet (less than 60 degrees F) and I brought it in to warm it up for bottling. So, does anyone know what causes this? I'm not a concerned n00b, just curious to know what causes this, as I have not seen it (more accurately--noticed it) in other beers.

That's the yeast settling out. As it sinks, the beer appears to darken because light no longer reflects off of their tiny, pale bodies.

DUH! Thanks, I should have been smart enough to figure that one out! So what do you guys think, rack to secondary and give it another week or two; or, just bottle it up in the next day? It is a wheat beer, so I don't expect it to be super clear.

I think I'm going to just bottle it up tonight or tomorrow. It hasn't changed much, although it was only overnight, and I don't mind my wheat beer being a bit cloudy. Plus, it should just about be ready in time for Thanksgiving!

Took a gravity reading a gave it a taste test last night. SG=1.014, and it has a hint of orange to it. Not too bad, although it has a real thin, light mouthfeel to it; I was hoping for something a little fuller. I'll be bottling tonight, and will give a report around Thanksgiving.
