I brewed a holiday ale two weeks ago, and there a tiny white spots on it. Is it mold?!

What are yeast rafts? Thank you for getting back to me. I hope you're right!
 
Nope, just yeast rafts- little bits of yeast floating on the top of the beer. They're often buoyed up to the surface of the beer from rising co2 currents. The surface of our beer is rarely free of everything.
 
Excellent. Thank you. I was worried. This brew is for our annual Christmas party, so I was going to be quite bummed if it was wrecked.
