Big starter question.

[Motorbikeman]

Need a big starter bud im limited to a 2 L flask.   

how would I go about getting 3L of a starter from it.

Maybe split it, refrigerate half and go again??

You could make a 2 litre starter and decant some of the yeast into a sterilised jar and then ramp the flask back up again.

Talking 3 days of mini beer making so.

Why such a big starter? You doing a lager?

Yeah.  Im planing a simple German Pilsner  with WLP800 Pilsner Lager Yeast..   

What to get her off to a good start.

Similar question. Also looking to get a large starter going for a lager using washed yeast.

Brewers Friend Yeast Calculator reckons I need 2 step-ups.

Is it enough to do the first 'starter', crash cool, rack off the spent wort and replace it with fresh wort?

The white labs packs are big enough to pitch into 4-5l which is what I'm doing tonight.
Yeast has to be fresh and stored well.
Otherwise pitch into 1-2l then crash cool in a fridge pour off the wort and introduce fresh sterilised dme up to 4-5, critically the temp has to be the same if you are adding one to the other. Stir plate always in a very cold room 10-12 or temp control fridge this time of year.
You can build at higher temps but if you think about it you are building at 18 say and then you try and ferment at 10-12, poor yeasties get confused and won't thank you.

Thanks CH - plenty to consider. Will give the starters a go and see how it's tasting before pitching anything.
