Update 2007-11-06: Sorry wine enthusiasts, it appears that CyraKnow is now offering only language instruction.
CyraKnow offers an instructional series on wine with Mark Phillips. Currently, they have 3 programs to choose from on their site: Enjoying Wine, Selecting Wine and Wine Regions. According to the system requirements, this only works with iPods (except shuffle or first generation).
a sample track and see if it might make your wine drinking experience more enjoyable.
