|This café opened as a retail beverage operation to complement their roasting. And they've done a stellar job of it. It's a very open space, with tall ceilings, modern light fixtures, and an exposed concrete floor. There's a large, round central table for standing at, a few side tables, and stool seating at the Congress St. tall windows. Major points for offering three different choices of coffee for their espresso - at review time it was Barrington Gold blend, Brazil Conquista Reserve, or Hawaiian Maui Mokka in Anfim grinders. Using a three-group Synesso (with naked portafilters, we might add), they pull shots of Barrington Gold (rated here) with an even, medium brown crema that dissipates, but it remains an integral, time-sensitive cup. It has a heavy mouthfeel and a dense body underlying flavors of tobacco smoke and molasses. Smooth, heavy, and very tasty. Though acid fruit bomb fanatics may want to steer clear. Their milk-frothing is good, with detailed latte art, but it is a bit milky and lacks integration with the espresso. Just to prove it can get even better than the ratings here for the Gold, their Maui Mokka shot has an even, darker brown crema, a bit of firewood in the nose, and that lovely, characteristic deep chocolate bomb flavor that made us fall in love with the bean well over a decade ago. One of our favorite shots in Boston.
