barismo: Cold shots in a chilled glass really hits the spot in this weather. Solid feedback so far. We are working to make them even colder, if we can. These puppies have the same strength (tds/brix) as a real espresso but the caffeine of a small filter coffee. Before we served it up, we sent it off for caffeine testing to make sure our draft products aren't unusually caffeinated. Testing came back good for us, but doesn't speak to other cold brew methods... so YMMV.🍵🤓
