Eighty-four percent of iced coffee drinkers say they are drinking more iced coffee this winter compared to last winter, according to an independent survey commissioned by Dunkin’ Donuts, Canton, Mass.

“As the company that serves the most iced coffee in America, we’ve seen iced coffee consumption continue to rise steadily in winter months, with iced coffee now nearly as popular as the classic cup of Dunkin’ Donuts’ hot coffee even during the coldest time of year,” said John Costello, chief global marketing and innovation officer at Dunkin’ Brands, in a statement.

The survey also found that 86 percent of respondents said they are drinking more iced coffee this winter compared to three winters ago. The majority of iced coffee drinkers — 90 percent — opt for flavor in their iced coffee with 30 percent choosing French Vanilla, 27 percent ordering Mocha and 21 percent of consumers preferring Caramel.

Fifty-five percent of those polled said they feel cooler and trendier when holding a cup of iced coffee. The percentage increases to 60 percent among ages 18 to 24, Dunkin’ Donuts reported.

Seventy-seven percent of survey-takers claim that iced coffee makes them feel more productive at work, according to Dunkin’ Donuts. In addition, 64 percent of respondents feel that iced coffee gives them a mental edge compared to colleagues at work.

Survey respondents also indicated that the most popular time of day for iced coffee is between 10 a.m. and 2 p.m., which was chosen by 41 percent of those polled. The early afternoon was second with 37 percent of survey-takers responding they go for iced coffee between 2 p.m. and 6 p.m.

Dunkin’ Donuts polled 500 iced coffee drinkers throughout the country during the last week of December 2011.
