Right now at the Starbucks Reserve Roastery and Tasting Room, you'll find a new kind of cold brew on the menu - it's Nitro Cold Brew. That's literally cold brew that has been infused with nitrogen: At the Roastery, they're using an East Timor Peaberry coffee for the cold brew, and then infusing it with nitrogen. The addition of nitrogen gives the cold brew a unique malty, creaminess to it. The cold brew ends up both looking and tasting a little bit like beer! It naturally develops a foamy head to it, like a beer.
However there's more! Starbucks is working on testing their Nitro Cold Brew in select Arizona locations. It's my understanding that Nitro Cold Brew is currently a single-store test at the Ellsworth and Baseline store, in Mesa, Arizona. The Nitro Cold Brew in Arizona, uses the standard Starbucks Cold Brew Blend, which is a blend of Latin American and African coffee components. Unofficially, I've been told that in the coming weeks there are plans to expand the test to about 8 Starbucks locations in the Phoenix area.
Here's what the Nitro Cold Brew looks like in the store:
