Ok, time for round 3 or 5 or 7 - I forget. Doesnt matter because Im committed now. Im gonna make some more booze or bust!
So, I have been reading up some more on the particular yeast I have. It seems to be especially popular with the ethanol fuel guys.
It has a hi alcohol tolerance of around 20%, so the fermentation didnt stop from too much alcohol - as my results show.
The fuel guys typically run at a specific gravity of 1.095 or so - which is twice what I had after diluting it last time and exactly what I had to start with. So it wasnt too much sugar.
They also, most dont add any nutrients - just sugar and yeast - but some do. Anything from boiled yeast to store bought stuff.
They do keep it warm - mid 70’s at least and up to hi 80’s.
I think the main problem I had in the beginning was too cold.
That plus leaky buckets - maybe.
Its interesting that for every two people who say to use an airlock, there is at least one person that just puts the lid on loosely or covers the top with a rag! The pro’s all seem to prefer airlocks.
Aeration at the beginning isnt always done, but it is fairly often. It is often done when re-hydrating the yeast, so Im doing that for sure.
So, Im going with an o-ring sealed lid and airlock. That got the most votes on Googling it and everyone here says to do that.
Im going back up to the higher level of sugar. That should get me a lot more alcohol in the end - up to 14.4% ABV in the final mash.
Plus, at the last second I decided to add some boiled yeast as a nutrient. I didnt so much - roughly the same amount as the pitched yeast.
So here is the formula.
8 lbs sugar
4 gallons of water (boiled)
8 grams of live yeast - re-hydrated.
8 grams of boiled yeast - actually just barely simmered for a few minutes.
I stirred the crap out of the sugar water after it cooled to about 86F. Then added the boiled yeast and stirred again. Then added the re-hydrated yeast and did an easy stir to just mix.
We will see…
