Starbucks found that much of its revenue comes from Gen Z and Millennials’ obsession with cold drinks. According to the coffee chain’s Q3 earnings, 75% of its beverage sales in the U.S. came from cold drink sales—and custom additions to chilled beverages like cold foam could “contribute to over $1B in revenue annually,” according to the company’s CEO. But it’s not just any old consumer that’s ordering cold drinks on the regular: Starbucks’ CFO says “it’s definitely skewed more towards a younger consumer.” Due to the spending power that Gen Z and Millennials have over the coffee chain, it’s even implementing changes like switching out ice cubes for ice nuggets to increase efficiency of the cold drink-making process. YPulse research shows that Starbucks is among the top mobile brand apps young consumers use.
