beer fermenting sludge

my worms love the grain malts,after brewing beer..I was wondering if anyone has feed them the sludge left in the bottom of the fermentation vessel ??

Wbgv; My worms are only two years old, to young to drink! Also I never made beer before so I don't know what is in the bottom of the fermentation vessel. If I had a small 1/8 cup to try in one spot, to see if they eat it. I would keep an eye on them to see what happens? Wild parties? Passed out in the front room, in front of the TV, all over the floor? maybe a lot of burping and passing gas? Sounds like my dad when I was young and at home. sorry I got carried away! If you don't think it's working out don't give them any more. maybe you might start out with a small amount and build up more over a week. Any way have fun. The party's at your house. Did you call for pizza?

We feed our worms the initial grains from our beer making - they do seem to like them a lot! we also get spent grains from a local brewery and add it to our regular feedings.
