Aussiedistiller, Home Distilling, Moonshine, Home Brew

Now I use Lowans bakers yeast for everything regarding spirit fermentation. I'm wondering if as I have been told the yeast mutate to their environment can I take a good scoop of grain which contains a good portion of yeast from my ujsm fermenter, wash it to remove grains and start another ujsm or cfw with a yeast the has mutated to be more alcohol tolerant therefore creating my own " house strain ".

It will certainly work to start a new gen weather or not its better i dont know. I always find gen 3 to produce more low wine than any other.(i do 5 gens per grain bed) This time round i am gunna try and be efficient grab as much data as i can see if i can work out why...

I know it sounds bad but the first 3 gens of ujssm I run as neutral as i find I get the best flavour after gen 3. After gen 3 I collect everything in my spare keg for the eventual spit run.

Worth a shot Plumby :handgestures-thumbupleft:

I used to use a starter for sourdough. A mother yeast.

Do you sour mash from bacteria or backset? Apparently lacto drives aciddy through the roof. I used to always think lacto was a vinegar infection that ate all the alcohol but apparently not. And is a welcome addidition by most when sour mashing, and the main reason for open top or wood fermenters..

You really ditch first 3 gens? How many gens you do on a grain bed?

I sourmash by backset, I turn the first gen to neutral every time, it makes a nice neutral has a sweet aftertaste. Then the 2nd and 3rd it kind of depends on how strong the taste is. If I think its not as strong as I like I neutralize it. I know it is a different technique compared to common practice but it works for me.
On a grain bed I normally go 12 or more gens, replacing about a third of the bed every 2nd gen.
Never had a lacto Infection, in the brewery or otherwise.

Seems like you turn over a lot of grain and could be a never ending mash. What % backset you use? I do 5 gens no grain replacement and 10% backest..

I did try 25% backset at first but I found after gen 4 or 5 it slowed down significantly, like 2 weeks for a turnround during summer. I now do 8 litres of backset per 45 litre ferment.
I do go through a bit of grain but at $15 for 25 kg I don't mind.

:handgestures-thumbupleft: sounds good. I was doing 25% and found same thing with slow ferments..

With most of these questions I always wonder "What have you got to loose?". I've had a crack at it and was only halfway successful. I think it was probably Moore 'me' than anything else, mainly because I wanted to do everything NOW and not wait to perfect one thing... early days.

There's plenty of YouTube vids that helped me a lot. I did it with Lowans bread yeast and when I reused it, it was slower to get going than the dry, unused yeast. I think, I will have another go at it, but more with speciality yeasts, not lowans.

I did try not adding any backset on every 4th gen when I was doing 25% backset but I found it easier to do a bit less for longer and to be honest most of the time my ferments are 50 litres or a bit better as most of the time my kids distract me while I fill them :laughing-rolling:

I will be doing a strip run this week so I will give it a go. I use to do yeast washing during my beer brewing days, so probably be a couple of extra rinses to remove the grain and any extra unwanted schmutz.

Love it! One of my favourite words!!

if you can do it, record a vid, be interesting to see and learn!

It works on so many levels.
In the kitchen, in the workshop even in the bedroom, " excuse me darling but you have some schmutz here " :laughing-rolling:

I'll try recording it Ezi but to be honest when it comes to that sort of thing, I'm about as handy as a glass hammer in a carpenter's tool belt.

Yes, 2 but I can just imagine the video I would get if I handed my phone to my 6 year old. " Here mate, record this please " I would get 25 minutes of him chasing the dogs followed by 3 minutes of him terrorising his younger brother. With me in the background cursing at him. Lol.
