Retail wine sales for 2010 appeared to be heading for a very positive year-end performance, based on Thanksgiving spending. Off-premise sales of domestic table wine through Nov. 28 rose 6% above the same four-week period last year, and continued on a trajectory to finish 2010 higher than any year since 2006. With the help of Thanksgiving entertaining, sales totaled $395 million at the chain food and drug stores where the Symphony IRI Group (SIRI) analyzes check-stand scan data.
