This morning Edie Tanem hosted a guest from a company called International Fruit Genetics -- Andy Higgins is an expert in grapes, and works with IFG to produce and market several exotic patented types of table grapes -- among them the sought after "Champagne Grapes" which are sold at select grocery stores nationwide.  Edie discusses all things grapes with Andy, and then we take calls from the KSFO Sunday morning audience!  Segments have been lightly edited to remove musical content.
