What do we taste in a glass of wine? Here to help answer that question on Taste Matters is Sebastiano Cossia Castiglioni, an entrepreneur, accomplished industrial designer and fine art consultant – not to mention the owner of Querciabella, one of Tuscany's most prestigious wine-producing estates. Sebastiano and Mitchell discuss the importance of biodynamic wines, terroir and taste. Learn more about how the soil ends up dictating the taste of wine and why cover crops are so essential in biodynamic wine production. Hear about lunar and solar gravity as it relates to plants and sustainable agriculture models that can help preserve the earth. This program was sponsored by Whole Foods Market.

"A good glass of wine is a wine that has a sense of place, history and breed. What I find interesting in a wine is when it tells me a different story."

"If you use chemical products, you're poisoning the planet, the plants and the final product."

"Cover crops are really the key to biodynamic wines."
