I'm a complete noob, and know next to nothing about the science of beer. Currently I'm drinking a sweetwater brewing company 420 extra pale ale. In my opinion, it has a horribly strong bitter aftertaste. Can anyone tell me some of the reasons it tastes like this so I can avoid brewing my own beer that is similar? I'm going to my local Homebrew supply store (very small section of a local hardware store)tomorrow to get the equipment and ingredients to pop my brewing cherry and I'd like to avoid this taste.
