Fermentation temperatures, a brief word of caution
Early december, I decided to put on a few extra buckets of wash to make sure that I didn\'t run out of drinkies over the festive period.
All SS triple distilled turbo\'s.
I normally just make a bucket up and leave it in the outhouse, where it usually stays warm enough to finish within the suggested times.
Anyway, mixed up 3 buckets which all started fine, but yes, I suspect you\'ve guessed it, the temperatures outside hit the deck big time.
In fairness, the temps etc earlier in the month have been exceptionally low. And while the 3 buckets managed to get close to finishing, they all got down to about 1.000
To try and rescue them, I\'ve had one indoors, one in the outhouse with a heater belt on it and the other one is left \"as is\".
The rescue attempts have involved aeration and warming up, though it appears that it hasn\'t worked.
So my word of caution is to make sure that you keep an eye on the likely temperature of the wash, because if we get another cold snap, it\'s likely to put paid to the yeasties and that it seems that while you often do get some temperature build up during the ferment, a normal sized batch of wash isn\'t enough to keep the ambient temp of the wash high enough so that the yeasties will still do their thing.
I\'m in the process of clearing and running them now to recover as much as possible, though I expect yields to be lower because of the failure of the wash to ferment completely dry. I\'m not gonna project how much down the yield is likely to be but whatever I get, will have to do on this occasion.
I\'m gonna have a hunt round as I\'d prefer a heater belt that will do 20C, and the one I\'ve got at the moment will only do a fixed 24C - I\'m happy to ferment lower as it does seem that the lower temp washes run cleaner when they\'re coming out the still.
Luckily, a dose of the seasonal flu has meant that the drinkies have been rather curtailed.....
Ah well, hopefully, back to normal eh.......
