It sounds like a fantasy for a wine lover -- spending every day tasting and learning about wine. Bianca Bosker went from rank amateur to cellar rat to the top of the wine-professional chain as a certified sommelier. She tells us all about it in her book, " Cork Dork: A Wine-Fueled Adventure Among The Obsessive Sommeliers, Big Bottle Hunters, And Rogue Scientists Who Taught Me To Live For Taste." It’s our July selection for Bookmarked: The Under the Radar Book Club. Guests: Bianca Bosker, author; and Jonathon Alsop, Under the Radar's wine expert and executive director of the Boston Wine School.
