Quote from Tony's site
"How much alcohol can you expect to make, knowing how much sugar you put in
? Easy. The theoretical yield is 51.1%, but you will get less than this,
around 48% because you lose some of the sugars to forming the small amounts
of other alcohols, esters, etc (eg 0.48 L of ethanol for every 1 kg sugar).
All going well, you should be able to capture approx 90% of this, ie 43%. So
... for say 5 kg of sugar, you should be able to get 0.43 x 5 = 2.15 L of
pure ethanol. "

4.5 litres.How do you do it? Even at the theoretical limit its close to 4.1
litres @100% . Please correct me if my mathematics is wrong as Im only a
newbie. Do you Step Up to 9kg?
Speaking of stuck ferments, thats a major problem down here as the temp
consistantly drops to below 18 C over night.
Hehehe 3 weeks ago we were trying to keep her cool!

My results from 8 kg of sugar and a turbo yeast in 25 litres of water
resulted always in approx 5 litres of 80% alcohol consistently.In the hotter
months i use the hi temp yeast with 6 kg of sugar and i get about 4.5 litres
of 78-80 % alcohol. May be i have a lucky streak. just keep trying. Regards
Jan.

• Thanks to Oz, Ken and Jan for your replies, I can see I am definitely way off in the quantity line. the target now is around 4 litres min. @95% per 22 litre

Thanks to Oz, Ken and Jan for your replies,

I can see I am definitely way off in the quantity line. the target now
is around 4 litres min. @95% per 22 litre wash.. So, if I may....

Oz,
"seal test" - do you mean from this a leakage from the fermentation
bucket that is allowing
oxygen in, or have you something else in mind ?
Temperature- This may be it - the yeast instructions say for max.
alcohol, keep temp between
19-23 deg. but I have had some problems keeping it
constant. I have just rigged
my latest batch with an internal heater thermostat
so we shall see
Ken,
Stuck fermentation
- I'm not sure quite what you mean.
my earlier batches were were down to around 990-1000
but I did not get a
starting point. the latest, and worse, started at
1120 but would not go below
1010. Also, As you seem to be using the same yeast,
what sugar quantity do you
use, what temp do you run to and how long does it
take to clear down ?
Jan, Should I be looking to vary the sugar volumes dependant
on temperatures. ?

Thanks again

Mike
• Oz, thanks again - I guess the wonderful heady aroma in the kitchen while I m cooking is taking a goodly amount, especially over 12 hours or so. Regards. Mike

No mate, not the carboy.
Remember. Any leak before your condenser allow alcohol to leave the system
as a gas and disappear.(gotta light!) Angels share instead of your share.
As far as temp is concerned the variation is the clincher. Keep it stable.
and yes keep oxygen out towards the end. When your wash is fermenting
violently then carboy leaks arent a problem as too much gas is coming out
anyway but as she slows down to a crawl/stop then it should be airtight.
Good luck
Happy hooching
Oz

Mike,i dont think you should change the amount of sugar you use as the yeast
uses up only the sugar it needs as far as i know. you better start looking
at better temperature control during fermentation. I have just finished
another batch. 6 kg of sugar,high temp yeast and 25 litres of water.
results:4 litres of 80%.2 litres of shit, high and low temp alcohol, which i
keep for a second distillation. Keep up the good work. Jan.
