TN-109 – Beer Hop Extraction

The practice of beer brewing is seven thousand years old and has out survived most of the cultures that drank it. While the ancient Babylonians, Romans, Assyrians, and Incan cultures can no longer partake in the nectar of the gods, striving to brew the best beer is still a prevalent goal.  One of the methods to improve the flavor of a beer is to enhance the intensity of the hops.  Supercritical carbon dioxide hop extraction is a method to obtain hop oil extracts with high concentrations (both yield and purity) and quality (less artifacts).
