Default Spent Grain: Slight Sour Smell?

Brewed up a batch yesterday. Took some of the spent grains, put them in a thin layer on some baking sheets and slid them into the oven on low to dry them out over night. I woke up and they were still slightly damp and had slight sour smell to them. Has anyone experienced this before?

I'm wondering if possibly i created an incubator for mold.

It's lacto. I learned that it takes a mere 2-3 hours for lacto to take hold and sour the mash post vorlauf. Your drying conditions must not have dryed fast enough ahead of the bacteria.

HA! Slightly sour? Try leaving them in your mash tun overnight. They take on a wonderful bouquet of vomit and rotting meat.

I have a buddy that I trade spent grains for fresh eggs. He let a batch sit around for a week or so then picked em up and put em in his car. They spilled. He came by about a week later, knocked on my door and said "come out here-take a whiff!" I had no idea what had happened but that might have been the foulest thing I have ever smelled...and I used to be a plumber!

Said the chickens loved them!

Chickens and barnyard animals can eat it regardless.
I give probably 1500# a month to a lady who feeds her chickens, pigs and goats with it and it smells like hell when I load the 33 gallon trash cans in her truck.

How did you set that up, Nightshade? Did you already know the woman? Put a notice on Craigslist? I'd really like to do something productive w/ my spent grain rather than bag & toss it!

Wait. You're not talking about beer, right?
You're talking about beer. That could have been a whole lot more fun.

It's really good compost if you don't want to throw it out. If you have a dog...http://www.homebrewtalk.com/f39/spen...cookies-87097/
