Whether you like it regular, or ristretto, or long, or Americano, the espresso needs to be smooth. There is some slight bitterness, but it should be very faint. The taste should remind of caramel. If you don’t have any idea of the taste, just go to a good coffee shop and order one. Go for a few days, and try to explore different baristas, and different times of the day. This will give you a great idea. If you don’t like it, and you know the coffee shop is a good one, give up, this is not for you. Some people just don’t like espresso. My wife, for instance, will only accept one if there is no other coffee around. At the end of the day, you have to like it, and you should make it your own.
The Saeco PicoBaristo HD8927/47 Super-automatic espresso machine is a Best Seller on Amazon and one of the most popular espresso makers available in the market for good reason. This well-designed and made compact expresso machine produces a wide variety of great beverages automatically. It is also designed to minimize maintenance. The PicoBaristo provides the widest variety of push-button drinks of any compact super-automatic espresso machine.
It’s affordable (£70 at Argos at the time of writing; Dolce Gusto pods are priced at around £4 for a box of 16) and incredibly simple to set up and use. Simply fill the removable water tank with cold H2O, pop your chosen coffee pod into a slide-out drawer at the front, stick a cup under the spout and hit the power button. When it turns from red to green (a mere few seconds) the machine is ready. You then push the water lever either left (for cold drinks) or right (for hot drinks) until the desired amount of your drink is in the cup. Then slide out the drawer, expel the pod and throw it away.

The Achilles heel of any super automatic, brewing times are, in my opinion, far too short for proper extraction of the good stuff from ground coffee. Part of the problem is the puck diameter - 46ml in the Jura Capresso S9. The other problem (and I blame the Swiss for this and their gosh darn love for caffe suise), is that the grinder can't be dialed fine enough.

...I just bought this machine for my girlfriend's new kitchen. The water sensor in the water tank does not stay in place. Therefore, the machine cannot make coffee because it cannot determine whether or not there is any water in the tank. There is a tiny plastic cap that should hold the sensor in place. The cap doesn't clip in, and floats away as soon as the tank is filled. Therefore the entire machine doesn't work.

The Jura XS90 features easy-to-use controls for setting temperature, volume, and strength of the coffee or espresso dispensed. There’s a large bean hopper with an integrated bean sensor that will remind users to refill the bean container. There’s also a water level sensor that makes sure there’s water in the removable water tank. Priced at around $2,000, this unit is probably the cheapest Jura with a one-touch capability.
You also get programmable push-button controls for milk, hot water and espresso outputs and given the fact that the 1003380 Accademia dispenses great beverages on demand, it’s great for those who don’t like to wait for long before their drink is ready. In total, there are 7 buttons that you can use in order to prepare one of the following drinks hot water, latte macchiato, latte, cappuccino, cafe lungo, cafe and of course, espresso.
