Cap - With Homegrown Sweet Corn

[fraser_john]

Here are a few pics of the CAP process starting with the cobs of dried sweet corn, then the corn kernels in a bucket, the pressure cooked crushed corn (gelatinized), mash and the CAP in the fridge

Note the odd floating trub ball, never seen that in 9 years of AG brewing!

[edit spelling]

that is wierd.. is this beer being made out of 100% corn? or are you going to distill it to a bourbon?

John, the floating trub ball could be from fats in the corn, maize treated for brewing (or making polenta or cornflour etc etc) is de-germed

The germ of maize contains a considerable proportion of an oil of somewhat unpleasant flavour, which has to be eliminated before the material is fit for use in the mash-tun. After degerming, the maize is unhusked, wetted, submitted to a temperature sufficient to rupture the starch cells, dried, and finally rolled out in a flaky condition. Rice is similarly treated. (my ever trusty Encyclopedia Britannica 1911)


However your sweetcorn may not have contained as much germ material as agri - maize but seeing as you have it in one ball there you might be able to syphon most off maybe??

Should still taste yummy for a CAP As it happens I'm doing one today with Galena hops but using a kilo of humble polenta

edit: SB, I'm sure John snuck a bit of malt in the mash tun some where along the line :icon_cheers:

Hmmm, might get to racking it off now before the ferment actively begins then!

75% pilsner
25% home grown sweet corn

John, off topic but is that a glass carboy or, as it looks, some sort of hard plastic bottle, from springwater maybe? Looks awesome.

 

[fraser_john]

Totally off topic

It is a glass carboy, I have four of the suckers, they are great.

Back on topic though, had a feel of the stuff once it was racked off, was not oily in any way so not sure what it was. Odd bit was that most of the bubbles from fermentation "looked" like they were coming off the blob.

Nice one John, those pics are great, and nice work trying something unique & home grown!

I hope the point raised by Bribie doesn't cause any issues and I look forward to the result.

I'll be watching this thread with interest, John!

I think i would be a bit scared of that in glass. If the yeast pushes some of the corn into the airlock it will make one hell of a bottle bomb.
