    Once yeast has finished fermenting. So I use activity in flask. It will throw a krausen and when that has settled and no bubbles are making their way up the glass it's time to chill decant then step her up again ;)

    Usually in the starters I've spun up 24 hrs it's fermented out at warm temp but give it two or three if in controlled temperature..

    I made a two liter starter for lager awhile back a week before brew day spun it at 12 c for 2 days then cold crashed for two days then mixed up another 2 liter starter and spun that up. For brew day I dumped her all into fermentor :D

    I have had much more success buy having a 5 liter flask and make larger starters. In order to get a good amount of yeast propagation a half liter starter would need to be stepped up to a 5 liter starter. To do a 1 liter starter followed by another 1 liter starter doesn't get you the yeast count you think you'd be getting. It's talked about in the Yeast book.

    Yes your right.I started with 2 liquid packs first then added 20 ounces of dry malt.It doesn't look like much in the 800 flask but in a 6 inch Tupperware container it measured about 2 inches thick.I loaded tonight that into 24 oz of malt.It went to in work a few minutes ,I'll be a little short on count but its a 11 gal batch of brown at a little over 10 .Sort of a little hopped up (Janet brown)called broke ankle brown.Sorry I drifted a bit I use the yeast calculator brewers friend to go by .I,ll wash this batch and have all the yeast I need for another dark brew.

    No five litre flask here newmanwell I'm sure that yeast proporgation would work much better than my 2&2 starter;). What I did find is my fermentation on the 2&2 was probably 12 hour lag at 12c she was bubbling steadily next day after pitching. Today I'm only doing a 2.3lt proporgation and going to pitch the lot into lager I'm brewing today hope that fairs well. I won't know the lag time as I'm pitching and going on a little holiday :oops: hopefully she gets rocking whilst I'm away:).

    I have mine on a stir plate. Once i see krausen I'll let it go until it falls then let it go another 24 hours for oxygen uptake.
