I am going to make a DME starter with a gravity of about 1.030 and jut slurp up some yeast from inside the cornie and get my starter going. I have not harvested yeast before... can I assume this will work just as good as if i had washed the cake and kept some yeast? I see no reasons why it wouldn't.
I've heard that you don't necessarily want to re-use the yeast from either the secondary or the keg. That yeast would be the cells that didn't drop out, like they should have, when the fermentation was complete. I believe I heard it on one of the White Labs Sunday Session shows on The Brewing Network. They said that re-using from the primary is the best way to go. Anything else could present issues.
