It looks like Guiness.

The new rage in the artisan coffee world now turned commercially available at your local Starbucks. Coffee that looks like a nice cold Guiness served right at the bar at every other Starbucks on the block. I have two things to say about this:
- Love the rich creamy viscosity. The nitro brew is pretty sweet. With a rich crema head and a silky smooth texture and body of coffee flavor, you just can’t go wrong on a warm day.
- Miss the Reserve coffee. While this is a Starbucks specific comment, I noticed that they replaced the Clover system that served single origin coffees from around the world and from the most unique and rare of little estates in exotic coffee climates, and now sitting and built into the coffee bar is a nitro brew machine. Might as well serve real beer. Lol.
Ok, rant over. Summary of my thoughts is that Nitro brew is blissful.
