What was Keith’s motivation to explore wine faults in such depth and ultimately to write his book? What’s the difference between a fault and a taint? Why does Keith describe it as a “soft boundary” between good and faulty wines? How can technically faulty wines still be considered excellent? Which weird wine fault might surprise you to learn about? How can you differentiate between the three main types of wine faults? Why are inexpensive wines less prone to faults? How have changes in the cork industry significantly reduced the incidence of cork taint? What causes cork taint? How do wine faults cost the industry up to 10 billion euros? What might surprise you about the minuscule amount of cork taint that can ruin a wine? How can you tell when a wine is mildly corked?   Key Takeaways Keith was very helpful in his discussion of one of the main flaws of wine - when it’s corked - especially when it’s only mildly so. As he mentioned, if it affects a wine at a very low level, you don't get the mustiness and mushrooms or dry rot. Keith had a terrific way of not only describing the main faults of wine but also how you identify them. He summarized them as falling under three categories: microbiological, chemical and physical faults. I was surprised to learn that inexpensive wines are actually less prone to faults, but Keith’s explanation makes sense as to why that’s so. They’re produced in a more factory-type manner as opposed to artisan wines and natural wines.   Join me on Instagram, Facebook and YouTube Live Join the live-stream video of this conversation on Wed at 7 pm ET on Instagram Live Video, Facebook Live Video or YouTube Live Video.
