Fermentation temperature

Postby Handyandy180 » Wed May 01, 2019 10:02 am

Hi All
I have just bought my second 30l fermenter and now have a Weetbix/Allbran wash on the go and also a Turbo wash on the go.

The Turbo wash was started mid day yesterday 30th April
When I ordered the goods for my local HBS I inadvertently ordered the Turbo 8 yeast, carbon and clear, on realising my mistake I rang them up and enquired how it would affect my wash. They advised to use 8kg of sugar which would increase ABV unto 20% and carry on as normal, which is what I did.

This morning there is an eggy smell in the spare bedroom where I ferment and the Turbo wash temperature which started at 30 degrees has now reached 34 degrees.
Having previously read that yeast dies off at high temperatures, I have sat a fan in front of the fermenter (though it may not do much good) to hopefully lower the temperature and remove the odour
Has anyone else ever had this issue and how can it be avoided
I"m assuming that this isn't normal

Many thanks

Oh by the way my previous WB/AB wash turned out fine and as mentioned earlier I have another WB/AB wash going along side the turbo. This is an experiment on which I think is the best quality wise. I am expecting the WB/AB will come out on top!

I remember from my turbo days that 25°-30°C is a good range.

I wish you better luck than I had with turbo. For me, I always got odd smells from it and never made a good liquor.
20% ABV is rather high and can push an already stressed yeast (from the turbo nutrients) into off-taste territory.
I'm not out to bash your method, but just a regular bakers yeast performs well --not to mention at a lower cost.

Best of success to you, my friend!

Thanks for that fizzix I've brought the temperature down to 30 degrees now and will leave the fan on to lower the temperature further and we will see how it goes. As I have said its more of an experiment at the moment but will probably stick to the WB/AB in future, Cheers

I am new to this but thought I would share my two cents worth.
Have done one turbo wash that tasted like shit compared to TPW and FFV
I have now completed one TPW and two FFV washes.
As for temperature I use two fermenters in a fridge and am not to worried about the temperature of the fermenters. I keep the fridge at 26 degrees, plus or minus 2 degrees using a temp controller and all works fine for both TWP and FFV.
