Are you doing the acid rest on the corn prior to cooking? You have to look for it but it is mentioned in Pintoshine's thread over on AD.
http://www.artisan-distiller.net/phpBB3/viewtopic.php?f=11&t=1044

"And yes I do get 1.060 from that ratio. The acid steep is commonly used in the wet milled cornstarch extraction industry. It increases starch yield by 35% because the zein protein(not water soluble) and the starch it holds together are aided in separation by the weak acid. The other binding protein glutelin is converted using lye. Since there isn't too much of that and is mostly in the germ, the weak acid treatment is sufficient."

I am intending to use the acid steep and the pre malt process when I start doing this.

Great vid there A...love muttley at the end..

That "burnt" problem...I was reading only yesterday about this guy with this prob..he puts it down to the sugar left in the wash that burns on the element.

What he does now he starts the boiler of slow at (I think) 700 w...then up to 12oo w...then up to a working temp...he says that has stopped this problem.

Yup, sadly a pretty shitty result.
Cute dog though!

I've just stripped this tonight, quite disappointed with only half a demijon of strip from 26 litres of wash, it started at only 60% and I collected down to 20%

I think my mash efficiency wash pretty shit on this one, next time I'm going to use less corn and add a couple of KG's of sugar to each wash, it also smells quite burnt

It also seriously foamed in the boiler, I've got a video of it surging and foaming, I'll post it shortly, 26lt in a 50lt keg and you can see it foaming up through a 4" column!

Update

I filled my boiler tonight with 23lt from the corn mash I did in my Grainfather and about 3lt i got from my first attempt at mashing corn that I did in my AirStill, I'll strip it tomorrow and maybe so a couple of spirit runs in the airstill with it being a small batch.

I wash quite plesently supprised when I was washing out my 23lt carboy, the yeast sediment I was washing out had a bourbon'ish smell to it

I've had the same idea for rye...I don't know if what I've ordered is ever to turn up. I think an order off malt miller is due..

I'm half tempted to get some more rye and make a 100% rye whiskey after I've used up my corn, apparently Rye ferments like hell, there's a lot of sediment in the fermenter from the corn, maybe 2" if it, not sure if I should just syphon off above it or try and stain some juice out of it.

I was wondering how you were getting on with it....this has been an interesting post, now we have more first hand insight from you, to what it takes when doing a corn mash....instead off just reading about it somewhere on the net.

I'm still waiting for my Rye to turn up...I'll not order off this guy again.

Checked my wash last night, it's at 1.000SG now, I was worried it wouldn't get to 1.000 or below because of all the grain I used, I think I'll take it out of the fermenting fridge tomorrow so it can cool and clear.

I'm half tempted to do a spirit run or two it in the Airstill after I've stripped it on the big still, just so I can get something to test on some oak.

I must admit the thought of all the work involved in getting through all that corn is a little daunting!

Some suggestions ive had from HD is to keep it at 90°c for two hours to release the starch, I'm also going to reduce the amount of corn to 3kg next time, it means more washes to get through all the corn but won't be as tightly packed during mashing so I might get a better conversion.

This stuff has set off like a rocket! I pitched the Allinsons when it was still quite hot 40°c.

So I put it in my fermenting fridge with no power hoping it will cool down but it was still 30°c ambiant temp, the heat hit me in the face when I opened the door!

Well done bud, i thought you might have got a better s/g
with your set-up, 35ltrs to 26ltrs. @ 1.040 that makes me
feel good with my primative gear. i know i used more grain
but at least i know i'm in the zone.
Don't know how your going to procede with your recipe, but
when and if...take a cut from the middle of your heart-cut
and dilute...you got corn/whiskey-whitedog, it's sweet nice
but it's not whisky to me, that's what my cousin gave me at
a funeral in Chicago, not my cuppa.

cheers B_D

Ok so that could have gone better, before I started I was filling my HLT that's high up, I have a water pipe plumbed into it so I just turn the tap on.

Unfortunately I some how got distracted and returned to the guarage to find water spraying out the top through the hole my pipe goes in!! Half the guarage was soaked!!

Also about half way through my mash the thermostat tripped on the GF so it slowly dropped in temp towards the end, I started with 25litres of water in it and sparged with another 10 litres, all together I collected 26 litres at SG 1.040

The spent grain and corn

Pumping it into the FV

1.040

I also properly blocked my counterflow cooler with corn jelly!!, I managed to connect the output end to a tap and flushed it all out

Well I'll make all the mistakes first then lol

This grain bill just about fits on the GF
