Manual and semi-automatic espresso machines require more work than automatic machines but generally produce a better espresso. Semi-automatic machines are most popular among consumers. Espresso machines use either a pump or steam to create pressure, but experts say only pump machines drive enough pressure to create a true espresso with a thick crema. Pod machines use prepackaged coffee, allowing users to forego grinding the coffee themselves.

Reviewers say to look for the following when buying a home espresso machine:

  • The best espresso machines meet industry guidelines for espresso preparation: 1.5 ounces of water heated to 195 degrees Fahrenheit, forced through 7 grams of finely ground espresso at no less than 9 atmospheres of pressure (130 psi) within 20 to 25 seconds. This results in a shot topped with about 1/4 inch of crema, the golden foam that's a hallmark of good espresso.
  • Look for a pump-driven machine. Steam-driven models can't maintain the correct water temperature or generate adequate pressure.
  • Generally speaking, heavier, bulkier espresso machines can withstand more abuse. That's because they often use metal in their construction, instead of plastic.
  • Budget for a top-quality bean grinder. Mark Prince of CoffeeGeek.com says that if your budget is $500, you should spend half on an espresso machine and half on a top-quality burr grinder. He adds that the grinder is far more important [than the espresso machine]. Blade grinders can't grind coffee beans finely enough for espresso. See our companion report on coffee grinders.
  • Look for a cup warmer, detachable water reservoir and removable drip tray. Owners say many drip trays are too shallow, but you can position a bowl beneath them to catch any runoff.
  • Pod models are easy to use. However, purists say that learning to use an espresso machine is half the fun.
