Can a burnt mash be saved?

Post by nzl.james » Sun May 10, 2020 11:56 am

Hi all,

I was cooking my first large scale mash and it smells burnt and has some black kernels swimming in the mash.

Is it worth continuing?

It is a 100 litre mash with 22kg corn. I added the corn to a boiling pot with the gas still burning and continued cooking with gas for about 1 hour. I have let it sit overnight. Its time to add the malt (65deg C) but I'm not sure if I should waste the malt trying to continue?

In my experience, scorch carries over into the product, so it may be better to cut your losses. YMMV

That's been my experience as well. I hoped I could remove it by redistilling, but I was mistaken. It was terrible.

Haha thanks for the advice. Looks like a pretty clear consensus.

I have transferred the mash to a plastic drum, added 3kg of distillers malt and 2 packs of high temp alpha amylase (24grams total, that's the only enzyme I had) at a temp of 60deg C.

I want to continue the process for practise as I'm new to corn mashes. I was trying to add the minimum malt so not to waste it, but I still want it to convert and ferment.

No. A burnt mash is pretty much a lost cause.

The advice around here is usually pretty good James. If you search the forum you will get a bunch of threads contributed to by distillers who have made the same mistake before you. I've done it myself. I used it for lighting fires and for a sacrificial run on a new still head.

I can imagine Her Indoors not being too happy if you kick twenty gallons of porridge over on her lawn though. :D
