Default Pitching on yeast cake

I am finishing a diacetyl rest on a Marzen. In one carboy I made a starter with 2 WLP 830 German Lager yeast that I used a stir plate with. The other I did the same with WLP 833. I gave both two thirty second shots of O2 and shook them for a minute between and after each shot. The results where great. If I pitch my next batch right on top of the yeast cake, what kind of result should I expect? I will of course give the wort another shot of O2.

Or should I pour some starter wort on top of the yeast swirl for a while, then pour it into my next batch?

I use my cake without using starter wort and I get great results. I've been using a California Ale yeast for almost 10 generations this way to good results.

Yeah, I was just thinking that I would be putting 78 degree wort off my plate chiller on top of the yeast cake. I guess the most important part of the process is getting the right amount to harvest and repitch.

I've done it. Left an empty fermentation corney in the keezer for 2 weeks then pitched right on the cake. I made beer, probably one of my best so far. Right, wrong? My palate isn't that refined, all I know is that either the beer tastes good or it tastes nasty and it tasted damn good and saved me $4.75 on another pack of Notty. I will continue to do it at least until I start farming yeast.

You have no in between? Something is either good or it's nasty?

I harvest about a third of the yeast cake and repitch into the next beer. If not brewing for a week or two, I just store the yeast in a zip loc bag...very easy and seems to work well.

Okay so I just sampled my Standard American Lager that I brewed two weeks ago. 1.020 from 1.052. Airlock activity started almost immediately. I avoided rep itching because of the unfavorable results I had in the past. I have had great success this time with washing, measuring volume of yeast, making a starter, re pitching, and using a lot of O2.
