That's the part that shows my inexperience with this hobby. I know more by brand, than I do by style. The brown ales are a prime example. If you asked me if I've ever had a Northern English Brown Ale, I wouldn't know. At the same time, I love Newcastle and it is one of my favorite brands.
Many years ago, when I thought Bud Light was the ****, I remember seeing a poster a college friend of mine had. It listed all the different styles of beers and showed how some styles were very close (stout & porter) to each other, while others weren't.
