Corn Cob Mash

[Symon1963]

Hello All. I watched a video by YouTuber Stillworks and Brewing where he did a mash with corn cobs. He was disappointed with the fermentable sugars from the corn cobs and added sugar to bring the SG up to an acceptable level.

I’m wondering if anyone else has tried this and has found a way to extract more starches out of the cobs. I have about 8-10 dozen cobs coming my way and would like to try it myself. I would also be adding some oats to the mash and may consider flaked corn as an adjunct and maybe molasses. Would like to try and avoid adding white sugar.

Tips appreciated. Thanks.

Is money "no object" ? If so, you can buy a cellolase enzyme to break down the cellulose in the cob into fermentable sugars. Other than for its novelty, I can't see spending the time to do so.

Seems a bit silly. The cobs might have some flavor, but not much starch available for extraction/conversion.
Randy seems like a nice guy, but his videos are hard to watch, and the content is questionable at best. I'd say unless you're watching it for pure entertainment, move on to something else.

I like that Stillworks and Brewing channel. The main thing I don't like is that he does 'one and done' runs. I've messaged him before about trying a stripping run first and see if he prefers it one way over the other, but I don't recall him replying.

Yeah I don't see using corn cobs being of any benefit other than adding flavor, if it does add a beneficial flavor.

Probably right. Seemed like a good idea to use otherwise wasted materials. To use as a flavoring component along with other sugar sources might be a better idea.. thank you

I like his stuff. Will think about using just as a flavoring agent along with other fermentable grains.. thanks.

Best use for corn cobs is to smoke malted corn with em.

You may have luck if you can grind them up reasonably fine. Throw some YLAY at it and see what you get. No harm, no foul.

Corn cobs make a good soil adjunct.
