To make sour mash, I use a 55 gallon drum with a screw on lid, if you can find one.
fill about 1/2. To 3/4 with whole corn. Dont fill it plumb full cause the corn swells.
fill with water til it just covers corn by couple inches. Add 5-10 lb of sugar and 3-4 packs of yeast.
Stir it best you can and put lid back on and leave it loose enough to burp, or let excess gasses out. Let set for couple weeks to whenever, it will last a very long time.
I just hold my breath and dip it out with a bucket. Be sure not to get it on you or your wife will make you sleep outside.
Its like hog crap, it wont wash off.
