Coffee infused with nitrogen gas is coming to a Starbucks near you!

By the end of summer 2016, over 500 Starbucks locations will serve nitro coffee, a cold brew that has been infused with nitrogen, chemical element number 7.

Nitro coffee first hit the market in 2011 or 2012 (claims vary). In June 2013, Portland-based Stumptown Coffee Roasters installed nitrogen taps at its cafes. In 2015, by popular demand, Stumptown began canning its nitro. Late last year, Caribou Coffee, which is based in Minnesota, introduced nitro coffee on tap; by this past February 25 of its more than 600 locations offered the drink. This July, Starbucks becomes the third — and by far largest — chain to serve nitro, a coffee beverage known for having a rich, creamy mouthfeel and sweet flavor.
