For Cellar Craft - the letter corresponds to the month, the next two numbers are the day of the month, and the next digit is the year. I think the rest are just manufacturer codes or something. So your first kit should be February 17, 2009 and the second kit January 7, 2009. Looks pretty good!
I justreceiveda Cellar Craft White Shiraz that was 2 years 3 months old (BTW, did not get it from George) and it was oxidized- very brown in appearance. I did receive a refund. The retailer just lost track of how old the kit was and promptly refunded my money.
