(Wines&Vines) - Off-premise sales of domestic table wine grew in August by 8% over the same month in 2011, while 52-week sales rose 7%. The continued success of one of the biggest selling varietals, Cabernet Sauvignon, buoyed the numbers significantly—especially in the three highest priced segments, according to the Symphony IRI Group (SIG). Cabernet took the second-biggest market share of all varietals with 14%, lagging only behind Chardonnay (23%), in the 52 weeks ending Aug. 5. Sales of Cabernet 750ml bottles from all regions increased by 9% during that period and earned the highest bottle price hike of 32 cents at the same time.
