I have recently discovered that I have something settleing at the bottom of my brews. When i hold them up to the light I can see a thin layer of something.

I also help up a commercial brew and saw the same thing.


What can this be?
 
Yeast. You should have yeast settling at the bottom of your brews! That's how the beer gets carbonated in the bottles - you (hopefully) added your priming sugar before bottling, which reactivates the yeast to produce more CO2 and a bit more alcohol. Since the bottle cap is a tight seal, the CO2 stays in the beer and gives it all those nice little bubbles.

When you pour your beer into a glass, leave a little bit at the bottom, so the yeast doesn't get in your glass. Tell your friends, too, otherwise they'll think your beer tastes weird.

Some commercial breweries bottle condition, too, which is how people harvest yeast that's often unavailable to purchase (Pacman, e.g., or Bell's house strain).
 
You are mostly looking at yeast settling to the bottom. You will also get some random trub and stuff that doesn't settle out in bottling.
