So I mashed my Kentucky Common yesterday like normal for an hour and let it sit for 24 hours with the lid upside down to let it vent (don't know if that was a bad idea or not). Earlier today it seemed fine. Slightly soured and bad smell, and still looked yellow. I just got back home and I am about to sparge and it now has mold on it. I don't really know anything about sour beers. Is this ok or is it bad? Should I go ahead and sparge and boil or will it taste like crap regardless. Any help would be appreciated. Thanks.
Edit: Scraped off the top, smells much better. Sparging now and will taste the full wort after. The bottom of the wort tasted good. We'll see. Next time I will be keeping it sealed.
