I put two bags of corn in a plastic 30 gallon garbage can, add a gallon of agricultural molasses, then add two gallons of hot water wiith 3-4 packages of yeast added, and let it set for a week or so. It begins to smeel quite loud after a week. I then dig a couple of 3-4 foot deep holes with the post hole digger and fill them with the mixture. It does attract the hogs. You can usually buy agricultral molasses at a feed store, it is used to make cattle feed, or to feed as a supplement to cattle, it is fairly cheap.
The hogs will continue to root in the and around the holes until they have ate all of the corn.
I think one of the best hog hunting trips I ever went on was back in 1964, North of Macon, Ga ,in the Oconee National Forest. Bootleggers has dunped a large amount of mash along a creek, the hogs stayed on it until it was gone. You could shoot one and it didn't seem to concern the others. Aolder man thaat hunted with us said that was not uncommon for them to be attracted to a pile of mash, get drunk of it, and hang around untill it was gone. I wounder if they had a head ache the next day?
