Henry McKenna is a "Distillation Disaster" that should be pulled from the store shelves. The bottle I had was near lethal, and less than one ounce served me up a headache for an entire day. Never in my life have I had such an obnoxious experience. It's not only isopropyl, it's rubbish! Fortunately the store where I purchased it returned my money. Now I'm trying to get a refund at yet another store for a similar bottle of Evan Williams 1996 SB... (is there a noticeable pattern here?) although the 1998 was very good. In my estimation, something was very wrong with the wood.
