My first corn whiskey

all about mashing and fermenting grains

My first corn whiskey

Postby Swagin along. » Thu Aug 04, 2022 9:21 pm

This is what i have done
8lbs corn grits
20 lts water
Cooked to 165 degrees f for 2 hours removed from heat
Added 1.5 lbs of malted wheat, and left over night.
Added 2.9 kg of sugar, 1/2 teaspoon citric acid and topped up to 22 litres with tank water. SG1072 PH 5.72. Aerated pouring from boiler to boiler several times.
Pitched 1 packet pure distilling premium spirit yeast @ 26 degrees. Put lid and airlock on, started working after 1 hour, ferment stopped after6 days. Let sit with airlock on for 7 days. Removed lid and tested SG 1008. I was expecting lower, and the wash looks like skim milk ? Stilling in the morning. Any thoughts on this.

i'm still learning, but i'd be interested to see what the more experienced guys reckon.
is the mixture of lbs & kgs correct?
i get 1.103 (13.5%ABV) from that combo of corn/wheat/sugar in my app.
and 1.065 (without the corn), from just the sugar and wheat alone for 9.8%ABV
what temp did you add the malted wheat?
i'm wondering if the corn was converted :think:

I suspect swaggin means finishing gravity, not starting gravity.
I have started doing all grain beer with us05 yeast and it often finishes at 1.05 or higher.
Bread yeast and sugar washes always finished .990. I suspect I am not getting full conversion, or that there will always be a little up fermentable sugar in all grain washes.
Like I said I have only just started all grain. Much like the great red Simonds I am often wrong but never I doubt :laughing-rolling:

Wellsy
Surely you mean your FG is 1005 NOT 1050?
Depending on the malted grain used it is usual for a beer mash to finish fermenting between 1008 and 1012

Tank you for you prompt replies.
The starting SG after adding sugar and adjusting Ph was 1072 put into fermenter and then pitched 7 grams of yeast.
After ferment was complete the final SG is 1008.
Looks like that may be in the ball park.

Thanks Bluc, i feel more confident now,
The recipies said the corn mash should look like porridge , but it was far from a gelatinus consistency.
Yes,i would also describe it as muddy clay water.

i'm either doing my sums or learning wrong :smile:
swagins OG of 1.072/ FG 1.008 = 8.4%abv
without the corn, 2.9kgs sugar & 0.7kgs wheat malt in 20litres would get me 9.5%abv according to my brewfather app.
differences for me
i cook my corn at 190f-194f (plus i add high temp enzymes)
wheat malt has a relatively low DP
with all that sugar, i would expect my OG to be about 1.099 (well my app would)



swagin - did you do any iodine tests at any time?

That comes down to effeciency. Finishing low is one challenge starting high is another..
The fact you also do (high temp enzymes?) Most likely boosts sg..

I have finnished the run and ended up with 1.8 litres, thats heads hearts and tails + 200 ml foreshots.41/2 jars @ 400 ml per jar.
1st jar finished at 74 percent, and gradually dropped to 54 percent on the last half jar. I chose jars number 2 and 3, i dont have any sense of smell so the good wife thought those two smelt pretty good.
Diluted to 45 percent with tank water and we both had a night cap.
Tasted pretty good sitting on french oak chips for a couple of hours.

Bluc,the minister for the interior was cleaning out the pantry and asked what are we going to do with all these pears we bottled last year, well that to me was a no brainer so they are being converted to brandy, will post the method next week as fermentation is allmost finished.
