When the waiter pours a taste of wine for you and it's your job to inspect that wine for flaws, while the sommelier and your fellow dinner guests look on, this episode is your guide to how to taste that wine with confidence. Wine flavor scientist Dr. Rachel B. Allison and Rose Thomas go over the different smells and tastes that answer the question "How do you know if a wine has gone off?" once and for all. Even better, Dr. Allison tells us exactly how those rotten egg and wet cardboard smells (to name a few) got into the wine in the first place. (What is "barnyard" in a wine, anyway?) If you enjoyed the first part of RT's interview with Dr. Allison in S3E5, you'll surely enjoy another deep dive into the science of wine. Let the technical information empower you as a diner, wherever you are in your journey in wine. You'll never unlearn one funny fact about baby carrots.  Dr. Rachel B. Allison, a wine flavor scientist, educator, and competitive blind tasting champion who grew up bilingual in Canada. Dr. Allison has a Ph.D. in wine flavor chemistry from Cornell University, and an Undergraduate degree in Engineering Chemistry from Queen’s University.
