Starbucks Is Going to Serve Cold Brew on Tap. What Could Go Wrong?

You’ve already gulped craft beer and sipped artisanal pour-over. So naturally you’ve moved on to nitro cold brew. At least, Starbucks hopes you have—or that you will. Later this summer, the coffee giant will start dispensing this slightly sour, vaguely effervescent, nitrogen-infused version of cold coffee at 500 US stores. Selling coffee that’s dispensed like beer might seem like no big deal. But for the world’s biggest coffee chain, it’ll be a logistical feat.
