I honestly never liked Yuengling. When all I had previously had was BMC, I thought it was good, but I then tried Sam Adams and realized i didn't really like Yuengling. Then I went to a local brewery and realized I didn't like Sam Adams as much as I thought I did.
After I have learned more about beer and trying more beers (even before I started homebrewing), Yuengling always had a funny taste to it. Most of my friends and their parents, even my father, always drink Yuengling. They all like other beers that I think are much better, but Yuengling is their go to. I'm sure it has something to do with the price, and I'm sure it has something to do with attending colleges in Pennsylvania.
But when I'm at a bar that serves the Guinness big three (Guinness, Harp, Smithwicks) a local brew, and sometimes even some good German Lagers, I'll pay the extra two bucks for something that doesn't remind me of BMC.
