I don't much care for drinking, but I have tried various things through the years. It's funny that Old Milwaukee should be mentioned. Out of the different kinds of beers I've had, it's the worst. I probably do 90% of my drinking when I'm in Europe. That's every few years. I'm around friends who drink. Hardly any of my friends in the U.S. drink. I don't like drinking alone. So, for the most part I don't drink. Plus, in general, American beer usually just doesn't taste very good to me anyway. All joking aside, though, I can't even imagine a worse beer than Old Milwaukee. I can easily see how it could totally turn someone against beer forever. Even the cheapest German beer I've had is light years ahead of it. Of course, Dutch and Belgian beer are also very good.
Edit:
Now that I think about it, I am getting Old Milwaukee and Milwaukee's Best mixed up. It's Milwaukee's Best that I found so horrible. I can't remember anything about Old Milwaukee, but I've probably had some at one time or the other. But I can name other beers I don't like--Bud, for instance, is almost as bad as Milwaukee's Best. We've had this discussion before at the LBO. Even though it's supposed to be a cheap beer, the only American beer I can name which I kind of like would be Pabst. I haven't had any in a long time. But it used to be very inexpensive and it was well worth the money.
