Yeast recycling interest

[Manxnorton]

Hi all,
Well last nite was sitting looking on the craptop and saw yeast harvesting and yeast starter etc on YouTube...as you do when our lass has her soaps on.
Thinking of this...and I would like an honest opinion for all you lot know my 'limitations, brain retention is it worth it!!
9 beaver pelts for a couple of lager yeasts was niggling at me...
So I'm going to do the same lager (23l) and I think only use the yeast twice..not sure.
But the yeast is dry not liquid..
Any thoughts will be apreciate as always..
(Chippy-T your prob thinking "oh Bri's going to do online shopping again this week, for the eqt!")
Been good this week only ordered my recipe ingredients!!! I think!! Have to look at my notes...ohh! Twice bought some StarSan lol
Reet! I'm off to sort my water treatment for a brewday!!!
Thx

I pitched a second lager batch straight onto the w34/70 yeast cake after bottling the first lager on saturday and its going well. :thumb:

If you spend money on an expensive liquid yeast strain then yes sure harvest. grow starters .. Overbuild and split ect.

No reason why you cannot harvest from a dry yeast cake either of course , I think given the cost of dry yeast some just feel it isn't always worth the effort.. I guess it depends on whether and how quickly you're going to use that strain again ect..

mind you myQul says you can practically do necromancy on yeast so there is always hope..

It also depends on how tolerant your partner is on filling fridges up with Jars of "what the hell is that?"

I bottled whilst the mash was on and left the yeast cake in the bottom of the FV then when the brew was finished I dumped the wort ontop of the yeast, it got going in a few hours.

I just took some pics, there is less yeast than earlier as I top cropped some first thing this morning.

Even if you can't manage brewing and bottling in a single day just scoop out a couple of big spoonfuls of yeast/trub from the bottom of your fermentation vessel after bottling and store it in a sanitised jar. This will be perfectly fine for a week or two just to dump back into your next brew and it will go off like a rocket.

After that, it is probably a good idea to perk it up with a starter before using it for brewing.

Hi!
Somewhere (can't find it at the moment) there is a webpage about splitting a liquid yeast so that you get two brews from one vial.

Hi all,
Well at the mo I'm happy with every stage of the HB'ing journey...I.e. Getting every stage right...cleaning & sterilising, water treatment all the way to bottling/kegging...but I miss learning about yeast starters and keeping my own yeast for the next brew.
Reckon if I get the stages right my efficienty would improve, let alone my 'brain power' lol
Looked at the web a bit and I'm ready to invest on the kit to do it!
First I could use your help locating the eqt I need, due to my learning difficulty internet shopping...I get confused, stress lol
I think a Erlenmeyer flask is one of the first things? How big and how many?
What about a Hotplate stirrer?
And any other kit needs...
I'll would apreciate link so I can follow...like I said doing it is hard for me...simple shopping tends to get messy! Unless I write it down I forget what I've ordered and times I order twice...at times 3 times...dooo!
Really interested at learning, another task during the whole HB'ing journey.

Hello Bri,

Basicaly add 100g sparaymalt or dme to 1L of water, boil, for 15mins, cool, then add yeast and put on stir plate :thumb:

 

[MyQul]

Just so you know bri, you dont HAVE to have an erlenmyer flask or a stir plate. I just make my starters in a 5L demijon and shake it regularly

 

[cheapbrew]

Yeah I agree Michael, I started off with a PET 2L bottle and just shaking it every hour or so, BUT I know how Bri likes to get all the kit ! :thumb:

 

[MyQul]

Your right, and think an erlenmyer flask will be helpful for bri as their wont be any transfering needed. He can boil, cool and ferment the starter all in one vessel

 

[Manxnorton]

Guys I'm pmsl...you know too well lol
I'm chuffed bits for your quick reply and help, as you know how I struggle..your deffo on my Xmas card list :-)
