As close as it gets to authentic espresso. The coffee is potent and has a thin layer of coffee foam as real espresso should. The start up time of the machine is a minute max  in order to heat up, then simply I sent the capsule and enjoy your coffee. This machine is able to produce espresso in either single or double shot portions which is great  for a pick me up. The main downside of this machine is that it’s a bit noisey and that the water tank constantly needs refilling. Those points aside, this produces a great cup of espresso with the quick convenience of an at home brewing system.
