I just got an old keg from a barn. It is the old, barrel shaped type, not the cylinder shaped keg. The keg has one end cut off, but half way up it has a wooden bung (with Pabst written on it) on the side wall. My question is can I fill this thing up above the wooden bung or should I remove it and replace it with something else? I was planning on using it as a HLT or boil kettle, but this wooden bung has me worried and since it's half way up it would be at the 7.5 gal mark. Has anybody else here used one of these kegs before and what did you do with the wooden bung?
