I’m sure most of you can recall taking a Psychology 101 class. If you went to a state school like me, you most likely remember it as 400 people crammed into a 350-person capacity lecture hall. All of us trying to not fall asleep, picking out key topics so you don’t have to read the textbook and seeing if that cute girl in the front is sitting next to her friend…or her boyfriend. However, I’m also sure you remember everyone’s favorite coca plant advocate and dream analyzer: Dr. Sigmund Freud. While he originally developed his theoretical construct model of the psyche — id, ego, and super-ego — to explain the fundamental driving behaviors of the human mind, his model also gives us a little insight in to how the ingredients in beer interact with each other.
