Kegerator Owners - Can we talk about various processes?

[Ol' Grog]

Have you ever bottled? That's what is going to happen inside the keg if you natural carb it. Just look at the keg as one big ass beer bottle. When using priming sugar, your actually giving the yeast in suspension some "food" to eat. The eat and convert that sugar to alcohol and CO2. That CO2 is what gives the brew carbonation.

Sugar makes yeast reproduce which forms more yeast which causes more sediment when it dies and/or drops out of suspension.

Read a little more and you will eventually grasp the whole concept.
