Sharon Kazan Harris tells it like it is. She is unabashed in her opinion of what is happening in the wine trade and Napa particularly. With a home in Bordeaux France, she carries with her an appreciation of the old and new world wines and brings to the table this unique perspective.    When you visit downtown Napa, the tasting room Mia Carta represents her RareCat brand of wines. You will be intrigued if you are fortunate enough to catch her working. In the meantime, have a listen.   PK
