I'm thinking to get some spent grains at a local brewery and make some treats for our community fair as I think it's a great idea.
How many treats do you usually get out of the recipe?
Also, since I don't brew myself, I'm thinking of drying the grains first so I can use them later. Has anyone been drying them? What would you suggest is a quick and easy way to dry them?
Thanks for your help!
Every brew day, while waiting on the boil I make a batch of cookies for the pups ..
Full size cookie sheet I get 117 cookies (these are not food, but treats, so I make um small about 3/4 x 1")
That takes 4 cups of spent grain.
Then I bag up 8 more cups in two bags (4 cups each) and freeze.. Do not dry, just drop um in the deep freeze.
Pull a bag out day prior to next batch... dump the bag in the mixer using the dough hook, add the other ingredients and 5 min later it is ready to roll out on parchment paper covered cookie sheet, score and in the convection oven it goes.
45 min at 350
remove cool a few min to help solidify , brake apart, and in the oven they go again at 275 (lowest my convection will go)
3 hours later, they are very dry... I have tested with a moisture meter and I just dump them in a zip loc for treat time.. never had any moisture condensate in the bag or any mold grow.
I used my dehydrators once.. left them over night, they dried fine,, but the racks are always a pain to clean... so I went back to the oven.
Bottom line, a typical 5 gal partial mash / extract brew batch for me, leaves me enough grain to make at least 6 batches at 4 cups of grain per batch.
