Created with ease-of-use and convenience in mind, the Gaggia Unica is equipped with everything you need to go from bean to cup. It has automated grinding, tamping and brewing capabilities as well as has a straight-forward interface perfect for home use. Reasonably priced, the Unica makes the most of its small footprint, integrating solid features such as a ceramic burr grinder, 15 bar pump, swivel base, removable brew group and Pannarello steam wand. This well-rounded espresso machine actually shares the same internal components as the high-end Gaggia Platinum line; at a fraction of the price, the Unica is recommended for value-conscious coffee lovers. We recommend using only light to medium roasted coffee beans for best Unica grinder performance. Dark roasts with more surface oil on the bean, or oily beans in general tend to inhibit the grinder performance. Do not use Starbuck's Dark Roast, or the rebranded Starbuck's Dark Roast like Pete's and Kirkland Dark Roast Coffees in the Unica. The surface oils on Dark Roast beans will certainly cause the grinder to jam and fail.
