(Wines&Vines) - Off-premise sales of domestic table wine shot up 11% in April over last year, largely due to a very positive Easter holiday. This high growth rate in the four-week period ending April 15 also lifted the 52-week growth rate to 8%, according to Wines & Vines’ analysis of Symphony IRI data. Easter is the only major holiday that falls in different months from year to year, and it has become a wine-drinking occasion for Americans, so its effect on monthly sales data is very dramatic. In 2011, Easter was celebrated April 24, about as late as it gets, while this year it came April 8.
