Illy unsweetened canned espresso

When I'm in a rush between flights at the airport, I sometimes buy a canned Illy espresso from one of the stores in the terminal. It's got 6.8 ounces of coffee and 10 grams of sugar. I don't love sugar in my coffee, but it's better than no espresso. I recently discovered that Illy sells unsweetened versions of the espresso. It's pretty good, and I like being able to grab one from the fridge when I'm headed out the door. I wish the TSA would let me bring it on the plane.
