OK not exactly specific to this topic but don't think it's worth starting a new thread for.
I made my second starter with a tube of WLP028 to freeze the yeast as outlined.
It was a 2L starter, ~1.030, on a stirplate for 48 hours, cooled in the kegerator to approx 7degC for 18 hours and it fell pretty clear. I tasted a little and it tasted like fermented beer. Poured off all but about 30mL of beer, and swirled the remaining up to suspend the pretty thick sediment. I managed to fill about 10 tubes with 10mL of medium-thin slurry so about 100mL of slurry was gained from the 2L starter. But judging from...

Does what I got (100mL/3.4oz slurry including hot break) sound about right? Seems like a small amount of yeast from such a large starter. Was 48 hours too short? Did I bugger up somewhere?
Cheers. |

After decanting the beer and adding back distilled water, I harvest about 180ml of slurry from a 1L starter and that settles out into about 60-65ml of compacted yeast.
1.030 is a little low (I use .040) and I would have stepped up the starter from 500ml to 2L in 500ml increments. Also, be sure to use a foam plug or foil instead of an airlock to encourage air exchange.

I use a stirplate, should I not be using an airlock?

There are lot of people that do, but presently CW says no. Airlock don't allow air into the vessel. |

Wow, cool...So tinfoil is permeable enough?

The foil is not permeable, but it's just draped loosely over the top as a dust cover and crimped a bit so it doesn't fall/blow off. Look at this pic from the beginning of the thread.

Thanks, I was using foil over the top of the flask.
I started with a 'pitchable' vial from White Labs, is stepping up still neccessary?
Cheers. |

No, but it seems to me that you end up with more yeast by stepping up than starting with a full wort.
