Cold coffee sales are soaring, thanks to Millennials.

Cold coffee sales are soaring, thanks to Millennials. Young consumers are opting for ready-to-drink versions of coffee, one of their favorite drinks, from supermarkets, and they’re motivated by convenience and cost. Sales of refrigerated, pre-made joe went up 29% over the past 52 weeks through early September, according to IRI. Top brands are looking to tap into the $2.7 billion industry for ready-made coffee, and even though Starbucks has an early advantage, Dunkin, Peet’s Coffee, and others are making sure not to miss out.
