What is the worst beer you have ever tried?

Lots of blow back going on against Bud Light these days. I’ve never been a Bud Light fan so they didn’t lose my money, they just never had it. But this got me thinking: what is the worst beer I have ever had? I thought long and hard and had to settle on Old Dutch. It didn’t use barley or rice as a base…it used Corn. It had the consistency of motor oil and left an oily film in your mouth. I tried this when I was 18 and all the kids at the party realized quickly how bad it was and even underaged kids wouldn’t touch it. So what is the worst beer you have ever tried?
