December apple volumes in U.S. retail stores were up 3.2% from the year before, according to new market research.

The December total was also 9.5% higher than at the same time two years before, according to Nielsen Perishables Data analyzed by Wenatchee, Wash.-based grower-shipper Columbia Marketing International.

“It’s very encouraging to see near double digit volume growth in December compared to the same period just two years ago,” Steve Lutz, CMI’s vice president of marketing, said in a company news release. “The numbers validate that consumers are buying more apples overall while embracing new varieties.”

Volumes of fuji, Pink Lady, Ambrosia and granny smith varieties all were up by more than 20% in December compared to two years ago, Lutz said. Honeycrisp volumes were up by 18% and romes by 17%.

Volumes of golden delicious, braeburns, jonagolds and cameos all declined significantly from December 2011 to December 2013, Lutz said.
