On the second day I draw out 8 ounces and dump it. On the 4th or 6th day If its ALL yeast, I open it up for more. I have got two cups yeast in one dump. Like springer, its every 2 days. I have a fridge full (a years worth) of washed yeast so now I toss it
Its the balls!
I think that is all yeast. I dumped the trub already. After it sits, the foam dissolves into the same stuff on the bottom and beer. I don't think it needs much washing.
I have used washed yeast twice. So far its great.
