Overnight mash

[simco999]

OK - here's what happened. Doing my usual wheat 50/50 with pale.

Mashed in at 69 - slightly high. So I didn't wrap it in a quilt as I normally do. Thats when it all went Pete Tong. The phone rang and I needed to go out to attend to a family problem.

Came back 2 hours later - and I thought bugger - I've heard of overnight mashes so its should be ok.

Well I came down stairs this morning to a bit of a pong. Popcorn and mushy peas came to mind.

Obviously the grain has swelled up and taken a lot of the water with it. I'm trying to rescue it now - 45 min mash at 67 ish - followed by a mash out at 80.

I will be doing the boil today as well.

Any thoughts guys and gals. Its just the pong that had me worried.

Sounds like a healthy dose of DMS, make sure to boil well with the lid off, you might drive most of it off.

Rapid cooling decreases DMS production, it appears that the long cooling period was the issue, as opposed to a long mash.

Similar thing happened to me over the weekend too with a wheat beer.

I did a late mash and sparge to boiler. Raised temp to 90C to denature any sac. enzymes and insulated then left to morning.

When I took insulation off in the morning there was a noticeable cabbage-water smell
(Wort was down to 75C)

Pleased to report that a 90 min boil removed all the smell
