Starbucks typically stops serving holiday-themed drinks on January 2nd. The reason for this is that Starbucks aims to keep the holiday spirit alive through the entire holiday season, and the last day of the year is considered the end of the holiday season. After January 2nd, Starbucks typically begins serving its winter-themed drinks such as the Iced Sugar Cookie Almondmilk Macchiato or the Chestnut Praline Latte.
