Yeast harvesting

[Martybhoy]

Could someone give me a guide as to how to harvest yeast from the FV on bottling day?

I have tried it once but didn't end up with much yeast at the end of it all.

Cheers

You can bottle or keg your beer leaving a small amount of beer to cover the leftover yeast in the fermenter
Ready some sterilised Manson jars in boiling water, lift out of the water, empty the water from them popping the lids on as soon as they are empty, sterilise a spoon then scoop just the top section of the yeast leaving all the old yeast and gunk behind, put into the sterile Manson jars, cover the yeast with a lite beer like bud lite, seal and put in a fridge
As I understand it the yeast will stay healthy if left like that for at least 6 months
The bud lite method is supposed to better then washing yeast as it leaves it undisturbed in a better environment

Sterilise a sealable jar and scoop up the trub at the bottom of the FV. Job done.

+1 on above and you don't even need to scoop it as you can pour straight from the fermenter.

So you don't have to separate the trub from the yeast?

When wanting to use, do you use everything in your jar, or just the stuff settled at the bottom?

I'm currently collecting a few at the moment and have three in secondary from 1st gen yeast trub collected from fermenter, refrigerated and then brought to room temperature before pitching.All three are 1.010,1.009 and 1.008 and had all started within a few hours of pitching.

Oh sorry forgot to say that I just shake the lot and pitch.Experimenting at the minute so try what you think and don't be afraid to try something different as a lot of people have done so since beer was invented and look where that has got us....:whistle::thumb:

I pour off the top, and usually make a starter. This is more because sometime my yeast is in the fridge for months.

Sorry folks, just to be clear, you don't bother rinsing? Just use the trub?

I definitely like this idea, but just checking that's what you do.

Also, from the trub from one fermenter, would you pitch all of this to a new brew? Or half, or a third?

I've pitched about 250 ml of the trub yeast mix on quite a few occasions and had really good results. Fermentation starts very quickly.

It's down to yourself and how much trub you have left as some yeast strains are more flocculant than others.

I have never rinsed. I just take a jar full. Usually re-use food jars but also got some kilner jars that I use.

I find the best thing to do is buy an SS BrewTech Chronical...

You know you want to.

Problem is now you're over thinking.As Leon has said just pitch a jar be it a jam jar for example and take it from there.[emoji106]

Just posting this for posterity.

Decanted my Passion Fruit IPA to secondary FV for dry hopping, and poured the trub from the primary into these two jars.

I'm guessing it'll settle through time and a chill?

What I used to do was swirl up the trub with some left over beer in the fv, pour into a sanitised 1l jar, leave for half an hour to settle and the carefully pour off the top half in to a 500ml jar, that way you get rid of a lot of the heavier trub. It never looked like I got much white yeast in the jar but it was enough to ferment another batch.

I prefer overbuilding these days, find it easier and no trub to worry about.
