I was experimenting on brewing low-cost but good tasting and potent beer. I bought a
packet of yellow corn meal. I boiled a big pot of water and added the corn meal(for yeast nutrient) and 2 cups sugar. I removed the corn meal after a while and put the mix into my brewing tub. I added active dry bakers yeast. The total volume in the tub was 1.5 gallons. The tube on top of the tub full of water rarely bubbled, but always I saw that the holes on that little piece of plastic inside the tube remained above water level, so gas was escaping. After 2 days I decided to test it. I got some from the spicket, and it looked almost solid yellow and smelled nasty and sour. When I opened the tub to dump it out, I saw that on top of the disgusting yellow stuff was a clearer liquid that didn't smell or taste putrid. I decided to dump it out anyway. The clearer liquid on top had a taste almost resembling bad wine, but no noticeable kick.
What was that liquid on top?
