Have you ever wondered why you can have a good cup of coffee one day but not the next? Join the Student Members of the American Chemical Society as we host the webinar “Coffee: A Chemical and Physical Perspective” on Wednesday, Oct. 20 at 6 p.m. in LSC 1211. Christopher Hendon of the University or Oregon will discuss how he uses chemistry and physics to isolate the most impactful variables in the reproduction of cup quality, while optimizing the usage of coffee to maximize profitability and flavor. We will serve coffee, hot cocoa, and warm apple cider and snacks. You’re encouraged to bring your own cup to reduce waste, but we will have cups available if you need one. This event is free and open to all. Questions can be sent to smacsttu@gmail.com.
