When you pitch your wort onto an existing yeast cake, what do you do regarding aerating? Do you still stir rapidly and splash heavily or will that upset the yeast cake and screw things up?

Thanks in advance!

Stir or shake away. It doesn't bother the yeast at all but get ready for fast and furious fermentation.

I just pour the cooled wort from a height, give it a few shakes, and it's good to go.
 
I am thinking that if you pitch on a yeast cake, there isn't a need to do any aeration at all since the yeast won't need much "growth" period at all.
 
I agree with aerating in this case!

It is very difficult to over-aerate and the yeast cake will need oxygen to properly grow and ferment. Go ahead and shake it up or use some oxygen.

Cheers!
Brad
