Does a Lager yeast make heavy Krauzen?

[Byran]

Yeah, could be.

I know all the guys I have talked to have always said "1 cup of slurry for an ale" and these are experienced brewers. My expectations with that are generally 1 cup will have probably 1/2 cup of leftover beer and then the non yeast portion.

I also thought (going against my first argument a little...) that Mr Malty gives you a pitching rate which will leave no growth phase when you pitch.

Well I can defiantly say that there was pretty much all yeast in the slurry I drained all the beer off and added a cup of water to break it up. Drained of the first cup and chucked it. Then used 2 cups of fresh stuff for the next batch. I just assumed it was all cool. I shall not do this again. Oh I also drank about 10 tappys before I done this which could explain a lot.

i dont often pitch from slurry, but when i do i try to seperate the trub, then pour the yeast in a schott bottle which has measurements on it, gives a good idea of how much pure yeast is in there after it settles

my understanding of mr malty is that it allows for the growth of the colony in the fermenter, and that you should pitch what it comes up with

Yeah, when I collect a cup it's most likely only 1/3 cup of pure yeast so the numbers add up. I'm not sure but I remember Mr Malty giving me much higher values when I last used it (like make a 10L starter for a 22L batch).

Don't be defiant :lol:

Let us know how it turns out anyway, I'd like to know if/how it negatively impacts the beer.

Lol Auto correct has mashed my words as usual as I am a beginner level typer
I will post a flavour update when possible.

10 litres is probably right, depending on age of yeast

mrmalty doesnt allow for steps, so i prefer to use yeastcalc

by example, i'm preparing for this weekends brew, the lager ferment of 40 litres of 1.048 using a 3 month old pack of wy2124 goes like this

1 litre starter on stirplate with 30 sec shot of o2 into headspace
24 hours
pour entire contents into 2.5 litres fresh wort, 30 sec o2 and onto stirplate
48 hours
rest, decant wort, rouse slurry and pour into 4 litres fresh wort, 30 sec o2 and onto stirplate

when done, rest and pitch slurry only

I really need dimi to get me an o2 bottle Im gonna make a stirplate too. I like makin stuff

Ok I just looked on mr maltys calculator and Its seems I have overpitched the **** out of it. 4 times too much.
Well there you go. So much for guessing...........

haha, that post just cracked me up. shouldn't be bad though right? are there any disadvantages of over pitching?

 

[Byran]

It seems so fletcher. I have had a fermenter that was behaving like a giant starter for a week keeping my yeast in the growth phase and creating a nice yeast farming device. It seems to have tapered off now and I have noticed quite a lot of DMS and sulphur produced but with such a large amount of yeast I would assume that most of the nutrients would have been eaten up which explains that. I have been Dresting this batch for a few days and it is fixing itself up. But there does seem to be a bit of a coarse flavour to the batch which is not exactly ideal as when using a lager yeast this is the exact flavour you are trying to avoid. Coarseness is for ales.........

I think ill be measuring my yeast from now on it will prob help my beers out a lot.

 

[Byran]

This beer turned out fantastic. Although I would have preferred it to not have had so much DMS it took a while to clean up. The carbonation got rid of the left overs and it tastes nice.
Lucky me.
