Krausen is the active live and happy feeding yeast on the top surface of the beer.This creates a layer of white to off white foam. Its a good way to tell whats going on in your primary. If your still not sure take a gravity sample 2 days apart and see if the gravity drops.
If it does, your fermenting.
