Lowans yeast not working

by **Colin Smith** » Thu Apr 11, 2013 8:37 am

I made 5 + 15 litre Tomato paste washes last night , being the first time making a TPW the first out the 5 washes I made I pitched the yeast at 32 degrees.. The other 4 I pitched at 28 degrees .. The 32 degree wash was bubbling away after 1 hour but the other 4 at 28 degrees are not bubbling yet and it's been over 12 hours... I used lowans yeast and put it straight in.. Did not activate first.. What should I do now.. ? Can I scrap the yeast off the top put it with some warm water and repitch it.. Or will it come good .. Hope my washes aren't fucked..

Just stir the yeast into the wash mate,if everything was done the same it'll work :handgestures-thumbupleft:

is it possible to show us a picture of the problem wash ?

Yeah, I agree with the gummibear ( :)) ).

I've never activated Lowan's yeast before pitching and it always fires away.

Were the fermenters cleaned out the same way etc?

:laughing-rolling: I've never even cleaned a fermenter,part from a quick hose out :laughing-rolling: :laughing-rolling:

Yes they were all cleaned out the same made the same way just one was a higher temp.. I will get home and give it another stir in .. Hopefully it works.. Thanks guys

Interesting mate. If it doesn't fire off after a stir, a bit more yeast won't hurt it. :handgestures-thumbupleft:

I sometimes have my washes stall because of what I believe to be insufficient aeration.
When this happens I pouring it vigorously out into another bucket, then back into the fermenter and add some extra yeast. Always fires off after that.

I use a paint stirrer on a cordless drill to aerate all my wash's while stirring the yeast in, think I paid about $12 at Bunnings for it :handgestures-thumbupleft:

I'm betting its bubbling by the time you get home. Keep us posted

Geez Mac,that's cheap for a cordless drill :handgestures-thumbupleft:
What breed of drill was it? :D

Was your yeast kept in the fridge after opening cuz I had problems with a couple washes with an open tub of yeast so bought a new one kept it refrigerated worked everytime and on the tub it actually says to keep in fridge after open meh

I've never had one stall, I've used yeast that's been in the shed for a couple of months, very rarely clean the fermenter, don't have heating, I'm with Sam, it's prolly be going soon.

Glad im not the only one haha, never seen the need to unless back in the turbo days..seemed to grow a bit of mould..but TPW never grows any..go figure, every few washes I grab some detergent then sanitize lol. as for airating the wash..I just set it on top myself with no stiring.ALWAYS picks up an hour or so later. the batch's I put on today took about an hour..but threw some vitamin B in with this one..and its bubbling faster than ever..hmm

i always use lowans yeast- that is kept in the freezer
i am lead to believe that is is best to soak the yeast in water to begin with. this helps plump up the cell wall before it goes into the sugar water. and that is better cos of osmolarity and science and shit (Mac probably will describe it better)

before that i would just chuck it in and give it a shake. never had a problem with doing that (but the soaking seems to start it off quicker).
being in Australia most of us will have some sort of water saving tap head (if not get one), they restrict water flow and add air into the stream (so it seems like the same amount of water is coming out, but only 50% of the water is). that should aerate the wash enough

My garden hose aerates pretty well too! :))

Damn sight better than the shit coming out of the tap..

Man I just tip the yeast in and walk away never had a single wash that hasn't taken off. I don't even stir it anymore.

If you seen me put a wash down you wouldnt say that :laughing-rolling:

Tip it all in, add yeast, then drill the fuck out of it with paint stirrer for 3 or 4 minutes... lid on.... then beer :D

Now hang on Mac :snooty: beer comes before,during and after the wash :handgestures-thumbupleft: :laughing-rolling:
