If you’re driving on Interstate 70 this afternoon and need a caffeine boost, the Starbucks in Rifle is giving away free peppermint mochas, vanilla lattes and more between 1 and 2 p.m. It’s part of a new holiday promotion from the coffee chain. For the next 10 days — Christmas excluded — 100 Starbucks stores across the U.S. will host Pop-Up Cheer Parties every day where customers can grab free tall handcrafted espresso beverages from 1 to 2 p.m.
