Science on Tap is a science lecture series where you can sit back, enjoy a pint, and laugh while you learn. Listen to experts talk about the science in your neighborhood and around the world. You don’t have to be a science geek to have fun—all you need is a thirst for knowledge!

The flames roaring, the ever-changing smells, the rhythmic sounds of the movement of the beans within the metal dragon. Inside, coffee beans are loosing water content, amino acids are catalyzing reactions with monosaccharides, oligosaccharides are undergoing caramelization, organic acids are breaking down while others are forming from the breakdown of these carbohydrates while developing pressures that can exceed 300 psi. At the end of the day, 300 volatile aromatics are transformed into over 1000. This craft, so often pictured in the artisanal idyllic is blending of science, art, and craft: bending fire to transform raw coffee into roasted beans.
In this session, Rob Hoos, author and Director of Coffee at Nossa Familia, will introduce us to the world of coffee roasting, as well as dive into some of the science that underpins and guides the profession of a coffee roaster. Looking at the process from start to finish, we will come to understand the basic design, chemistry, and thermodynamics of the process as well as dive into current research on the manipulation of flavor development during coffee roasting.

**A note on the suggested cover: Science on Tap is largely supported by money collected at the door from advance and box office ticket sales. However, we are committed to offering educational opportunities to adults who want to learn. If the event still has seats available and if $10 is a hardship for you, please come anyway and donate what you can. Buying a ticket in advance confirms that you will have a seat at the event.
