I am not any type expert on this. If the grain is fresh there is not alot of storage time with it, how much I am not sure. I know friend down the road used it with cattle from the brewery. He gets it by semi load he has mentioned the short time for storage. How short ?Has anyone tried spent fermented grains from a local brewer? If yes - what are the best to ask for and is it something that you can get and store, or does it need to be consumed rather quickly to not go bad?
Years ago I worked at a dock and we loaded 3 barges of brewers grain. After 3 days of loading for each barge pretty stinky, flies, maggots.
From what I was told, the top of the brewers grain would form a crust which would seal the remaining brewers grain in the barge which keeps it fresh as it takes about a month to get to destination in southern USA. There is about 1200 to 1500 tons of product in each barge.Then the grain was going to feed lots and also to be dried for feed.
A small brew shop might be worth looking into depending on how fast you could use it. Yes if you dry the grain it could be stored. There is alot of moisture in it. There is also many vitamins and protein. Maby there is a good way to store it fresh, I don't have any idea.
I have thought about trying to get brewers grains from one of the small brewers in town for raising pigs. Then again thought prolly to much hassle for 2 or 3 pigs.
