(Wines&Vines) - Domestic off-premise wine sales had a good month in January, growing by 7% in value and 1% in volume. That growth rate was the strongest since September 2012, and it kept the 12-month growth average at 6%. January is usually a slow month for sales. The total at the major food and drug stores analyzed by the Symphony IRI Group (SIG) reached $376 million. Higher priced wines and those packaged in 750ml bottles enjoyed even better growth.
